Belden introduces new EMEA distributor program

Belden has introduced a new program for distribution partners in the EMEA region. The new Channel Program, called Belden DNA, was launched in Brussels during a two-day meeting attended by key Belden personnel and representatives of more than 40 distribution partners.

The new Belden DNA program sets out to build the ultimate connection between Belden and its distributors, through selection and allocation of resources. Building on a shared commitment, the name DNA epitomises the concept of a DNA connection.

Belden DNA will be an exclusive community of the best distribution partners, dedicated to promoting Belden’s range of cable and associated products to their respective markets and territories. The program will allow the relationship to be a successful and mutually beneficial experience, growing together, creating Organic Growth to make both entities stronger.

Launching the program, Channel Program Manager, Phil Watts said: “Belden DNA is a new way of managing our distribution relationships and is designed to be flexible and fit with their business. As with any business relationship there are elements required, upon which growth can be developed and future business objectives achieved.

“Each of our DNA distributors’ very different characteristics determines the levels of reciprocal commitment, i.e. the commitment required for Belden and therefore the level of commitment they in turn receive from Belden. Essentially this means the greater the level of commitment they give to Belden, the greater the level of support their organisation will receive from Belden.”

Recognising the difference of each of the current DNA distributors and their business, Belden DNA has been developed to cater for multiple types of distribution relationship. Individual distribution partners determine where their organisation fits in.

Belden will provide different levels of service. DNA distributors whose business is structured such that they have a relationship based on increasing commitments, will be able to command increasing levels of support and service from Belden. The highest level will include timely, professional service to meet the demands of the distributor and additionally include greater access to Regional Account Managers, Marketing Communications team, Marketing managers and Portfolio reviews as well as increased training resources.

A dedicated team assembled to support our DNA distribution partners, consisting of a Channel Manager, Regional Account Mangers and a Coordinator. In addition a range of resources has been introduced, including an Opportunity Tracking program, a shared web portal and improved technical support facilities.

Phil Watts: “We believe this will be the best programme in the market place today and we fully intend, with our partners help, to keep Belden DNA as the partner programme to benchmark against.

“Belden appreciates that to have a motivated and proactive distribution channel able to support the overall business strategy and deliver superior performance, requires a consistent and cohesive strategy. We believe that a motivated distribution channel will organically grow, whilst supporting the Belden sales strategy and deliver superior performance.”

Mr. Watts added “The Belden DNA programme is only one aspect of an innovative approach to working with our distributors. We will incorporate a full suite of traditional and multi media collateral to communicate, update and inform customers about Belden, our products and the markets in which we operate.”

Belden provides broadband solutions

Belden provides broadband solutions

Belden manufactures wire and cable broadband solutions that provide the bandwidth needed to build the infrastructure for today’s CableTV and satellite dish technology. At a recent Press Briefing, Theo van Rijn, Product Marketing Operations Manager for Belden EMEA, gave an overview of the company’s capabilities in the CATV or Provider market.

“CATV is a system of providing television to consumers via radio frequency signals transmitted to televisions through fixed optical fibers or coaxial cables. As CATV is becoming more established, FM radio programming, high-speed Internet, telephony and similar non television services are also be provided using the same bandwith.

“With wireless communication becoming a part of everyone’s life, people communicate more and more through wireless networks such as cellular phones, TV Broadcasting and WLAN. Increasingly, the networks serving them become Hybrid Fiber Coax.

“Belden has a complete range of products for this market. It includes one of the most comprehensive, economical and up-to-date selections of reliable 75 Ohm and 50 Ohm coaxial cable products on the market today. The distribution and drop coaxes feature Belden’s innovative, high performance Duobond Plus® shielding or Belden’s Duobond® II shield. Belden Duobond Plus® (Tri-shield) Cables have consistently outperformed the more elaborate quad-shielded cables.”

Developments
“Current projects in Fiber to the Home are driven by CATV operators. This is not a rapid change over as CATV operators want to extend the broadband coax life as long as possible. Telco operators are also slowly moving towards the fiber to the home, as they want to extend the Twisted Pair life as long as possible. The true drivers are new providers as they are looking to build completely new networks with extremely high bandwidth.

“Key considerations are the growing demand for higher bandwidth. The triple play use of that bandwidth: for telephone, internet and TV or HDTV, and the ongoing split between the roles of the network provider and content provider. Many countries – for instance in Eastern Europe – are now beginning to create their infrastructure.

“Belden has an impressive list of reference cases and a strong tradition of moving with the market to meet new needs for increased bandwidth and easy installation.”

Belden introduces Seamless Mobility for Wireless Access

As part of its strategy to provide a range of signal transmission solutions, Belden has introduced the 4th generation solution for Wireless Access which greatly simplifies installation and offers improved performance over current technology by providing seamless mobility, high security, no co-channel interference and unmatched system capacity.

Belden’s new Wireless Access System is based on the Channel Blanket approach which has many benefits. It means that users have true mobility by combining the freedom of wireless with the ease and simplicity of a hard-wired network. It combines voice, video and data networking and increases throughput. Access points can be anywhere and require only the simplest of installations without any set-up or configuration required. The system is easy to plan, install, test and maintain. MACs (Moves, Adds and Changes) are also easily achieved by simply altering an access point.

Chris Chandler, Technical Manager for Belden UK and Ireland says: “In today’s fast-paced communication environment, people need mobility without any limitations to their physical location. They need fast and easy access to information without any security concerns and without giving up the quality. Belden wireless solutions gives people what they need – being able to communicate and access information fast with full, seamless mobility, ubiquitous coverage, and robust client connections that simply do not drop.

“With its wireless solution, Belden overcomes the problems of cell-based WLANs. Users are provided with mobility benefits of the wireless with a wire-like performance which is simple and easy to deploy and maintain. As a result, both the users and the installers benefit from the simplicity of the system. Seamless mobility for wireless access is a brilliant example of what Belden can achieve for its customers in EMEA and globally.”

Conventional hard-wired networks are designed for people working at desks in fixed locations using a wall or floor jack to gain access. These provide some limited mobility but do not fulfill today’s need for total freedom with access from anywhere and multi-service flexibility tailored to the user’s business or personal needs.

Hard-wired networks were designed only to carry data and not intended for the simultaneous transmission of data, multimedia streams and voice traffic. Cell-based systems are plagued by co-channel interference which is the primary cause of diminished system capacity. Another difficulty is they require deep radio-frequency (RF) engineering enterprise coupled with the need to balance channelization, acceptable interference, transmit power and unique antenna selection for each access point. With the Belden Wireless Solution all RF-related complexity disappears and only a basic understanding of wireless technology is required.

The Channel Blanket topology means that each radio channel is used everywhere at every access point to create blankets of coverage. The result is seamless mobility with no security concerns, no roaming latency, no co-channel interference, robust customer connections that do not drop and the ability to design for a guaranteed and predictable level of service. It means no access problems from the wireless equipment itself, from the type of information required or from the physical location. The end result is network performance that is dramatically improved and transformed, giving universal coverage and unmatched system capacity.

Belden’s innovative system is easy to plan, install, test and maintain. It is a solution which eliminates the classic trade-off between coverage and capacity, providing the industry’s highest capacity and bandwidth and achieving this on several levels.

There are many benefits for the user as they no longer need to consider their proximity to an access point in order to achieve connectivity. They can be secure in the knowledge that their grade of service will stay consistent, calls will not be dropped and there is no need to consider the network at all.

The new system eliminates edge users and client bunching which are common problems with traditional systems. It offers the highest capacity through layered blanket which means it is possible to multiply the capacity at any given point in the enterprise network. In addition it boosts the total system bandwidth. The result is a seamless coexistence of all applications and all user types.

Belden’s Switch is the central component of the Channel Blanket architecture. Powerful and intelligent 6-port and 24-port switches manage all WLAN traffic and network management activities. They work with and control the operation of Belden’s BWAP-200 Access Points. This enables the same channel to be transmitted from every access point in the system, without the interference which plagues other WLAN solutions.

The system’s Access Points are elegantly simple. They require no set-up and no configuration. They are designed to delegate all network traffic decisions to the Switch. Because of their simplicity and the fact that they are powered by standard power over Ethernet, they provide a true plug-and-play architecture for implementing large scale, enterprise grade WLANs. Importantly, the switch software also provides high security and centralized software control which means that the access points can never be the point of a possible security breach.

Belden offers advanced products for building markets

Belden offers an extensive range of high quality, high performance products for use in industrial, institutional, commercial, educational and residential buildings. At a recent Press Briefing, Chris Chandler, Technical Sales Manager for Belden EMEA, provided an overview of new and soon-to-be-introduced products.

“Today, we create networks in every type of building. The complexity of these networks will depend on the number of attached appliances or computers and their connectivity requirements, but the basic objective is always the same: allowing individual computers to share data, perform business-related transactions or access the information superhighway. None of this can be done without structured cabling systems, i.e. a network in which all components are engineered and manufactured to provide optimal and adaptable performance levels according to industry accepted
standards.

“A properly designed and installed structured cabling system provides a cabling infrastructure that delivers predictable performance as well as the flexibility to accommodate growth and change over an extended period of time.”

10GX® IDC System
“Communication hardware is getting smaller and Belden’s new 10GX® IDC cross-connect system mirrors that trend. Considering the high costs of construction, Belden has developed an alternative system which not only saves on building space but also delivers unequalled performance.

“Belden’s 10GX® IDC System complements the 10GX Gigabit Ethernet infrastructure and meets TIA/EIA 568B.2 standard. This new high performance, space-efficient system is uniquely engineered to handle 10GBase-T data networking and multimedia applications with headroom to spare.

The new Belden 10GX® IDC System makes it possible to create large cross-connect systems which are space-efficient, easy to install and easy to maintain. The system is designed for 10GBase-T applications as a cost-effective alternative to modular patch panels.

Wireless Solution
“The new Belden Wireless Solution uses a unique Channel Blanket topology to allow each radio channel to be used everywhere, at every access point, thereby creating blankets of continuous wireless coverage with no roaming latency or co-channel interference problems. Its architecture is fundamentally different from standard WLANs, which use cell-based technologies that require complex RF Cell Planning in an attempt to avoid co-channel interference.

“Equally important, high throughput is achieved even when cell traffic is high. Full compliance with IEEE 802.11a/b/g protocol and security standards is maintained, ensuring seamless, zero AP-to-AP hand off mobility for latency sensitive applications such as voice and video. The system is exceptionally easy to deploy, configure, validate and maintain, providing plug-and-play flexibility to add or remove APs with no effect on the existing set-up.”

Optical Fiber Components
“Belden has been involved in the development of optical fiber components since 1972 — evolving to its present status as an international supplier of high quality, cost-effective optical fiber cabling systems. “Today, we offer users a complete, high-performance, end-to-end cabling system that supports both centralized and fiber-to-the desk (FTTD) topologies, as well as in-building or campus backbone cabling configurations.

“The Belden IBDN Solution is, however, much more than an assemblage of top-performing products. It represents a whole new approach to the methodology of fiber optic cabling. Belden systems are unique in their ability to offer both superior performance and a more cost effective, speedier and less complex installation process compared to more traditional fiber optic cabling systems.

“This assures the smooth operation of networks and provides for efficient network management — while continually reducing total cost of ownership whilst preparing systems for the future.

“The Belden Secure Keyed LC System is designed to bring a whole new level of security into network infrastructure design by enabling the physical segregation of any designated network segments. Based on the superior performance of the LC connector format, the Secure Keyed LC System offers outstanding features and benefits including six color-coded keying options for design flexibility and facility in network administration, tamper-resistant key design — front and back — preventing intruder access and high-quality ceramic ferrule to provide low insertion loss and excellent durability.”

New products for 2008
“Belden is set to introduce a new range of products for 2008. These include Low Smoke, Halogen-free (LSOH) Cat5e & Cat6 Patch Cords – both Cat5e Stranded and Cat6 Stranded & Solid Core – and a 50 ports telepanel with a functional and easy-to-use design. These telepanels have fixed cable guides prepared for use of Velcro tape or strips, 2-pair connectivity per port, “jacks” mounted as RJ45, enabling the use of general patch cables and they are available in white & black with numbering from 1 to 50.”

Belden introduces new 10GX® IDC System

Belden, a leader in the design, manufacture and marketing of signal transmission products has introduced the company’s 10GX® IDC System, allowing the building of large cross-connect systems which are space-efficient, easy to install and easy to maintain. The system is designed for 10GBase-T applications as a cost-effective alternative to modular patch panels.

Belden’s 10GX® IDC System complements the 10GX Gigabit Ethernet infrastructure and meets TIA/EIA 568B.2 standard. This new high performance, space-efficient system is uniquely engineered to handle 10GBase-T data networking and multimedia applications with headroom to spare.

“Communication hardware is getting smaller and the cross-connect system mirrors that trend brilliantly. Considering the high costs of construction, especially in the Middle East region, Belden has developed this alternative system which not only saves on building space but packs a communication punch which is unequalled.” stated Chris Chandler, Belden EMEA Technical Manager for UK and Ireland.

“Belden’s 10GX® IDC System complements Belden’s IBDN System 10GX Gigabit Ethernet infrastructure as cutting edge, cost-effective technology at its best,” he added.

The system is extremely flexible because it accommodates the configuration of large, wall-mounted cross-connect systems (up to 2300 x 2300 ports in a 6m wall) and the configuration of interconnect systems within racks. Traditionally, interconnects use modular patch panels but the 10GX® IDC System offers a lower cost alternative that is also easier to manage, change, adapt and relocate. The system’s termination kit includes all the components required to terminate 72 cables.

10GX® IDC can be used to build space-efficient, cross-connect fields for horizontal distribution or equipment termination. Typical applications are: Enterprise Network Telecommunications Rooms, Main Distribution Rooms, Consolidation Points, Data Center Main Distribution Areas, Horizontal Distribution Area and Zone Distribution Areas.
The 10GX® IDC System relies on various innovative enabling technologies which are designed to ensure outstanding 10G performance and to facilitate installation.
These technologies include:

  • MatriX IDC Technology or Module ANEXT Cancellation Technology which cancels out alien cross-talk between modules and provides a 15dB reduction in ANEXT compared with traditional technologies.
  • X-Pair Technology makes the connector virtually transparent to the signal carried over the cable twisted pairs. NEXT performance is 32 times (15dB) better than the specified standard.
  • X-Bar Technology or Module NEXT Control Bar Technology uses a plastic device to align the cable and optimize the termination process. This provides performance in the field similar to that measured in the laboratory.
  • 10GXn X-Connect improves Alien NEXT, NEXT and impedance performance. Cables are both round and flexible and therefore easier to install.

    Key benefits and features of the 10GX® IDC system include, unmatched 10G performance with guaranteed headroom for 10GBase-T application; truly backwards performance compatibility with Category 5e and Category 6 to help protect cabling investment; connection density of 72 ports per mount to save on cross-connect ‘real estate’, matching GigaBIX density and allowing an easy migration path for 10GBase-T applications; simple, reliable IDC Blocks which improve network uptime; polarization and color-coding for easy, error-free installation; innovative double X-Bar design; cut-to-length punch down X-Connect cables for reduced operating costs and improved network security; termination of connecting blocks using the GigaFlex® connecting tool or any other 110 tool.

    Belden has provided a single reference number to make ordering of the termination kit and components very simple. These include the mount, IDC connecting blocks, holders, front and rear termination bars, cable ties and screws needed to complete installation to the mount. An installation guide is also included.

    In addition, various system accessories are available including the Vertical Cable Manager and Labelling Kit to control bend radius and allow easy access, the Horizontal Cable Manager (with capacity up to 432 cables) to ease wall layout and a Permanent Link Universal Test Adapter for easy testing.

Belden expands line of DataBus cables for FieldBus applications

Belden has introduced new FieldBus Type A multi-pair cables and foil/braid cables. These provide installation flexibility in many different environments and where multiple or extended cable runs are required.

The number of devices possible on a fieldbus link will vary depending on factors such as the power consumption of each device, the use of repeaters, signal attenuation, type of cable used and distance. Because of the superior features of Belden DataBus cables, standard distance limitations can be exceeded without any system enhancements or any sacrifice in system performance.

Belden FieldBus cables are suitable for use in Class 1, Div. 2 applications and compliant with FieldBus Specification IEC 61158-2 (ISA/SP-50). They are also RoHS compliant and CE approved. Features include excellent electrical characteristics and low capacitance for long runs.

Cables are available with 22, 18, 16 and 14 AWG stranded tinned copper conductors, and as multi-pair cables available in 2 to 24 pairs. Versions are available with Beldfoil® shields and Beldfoil Plus Braid shields.
As always with Belden industrial cables, for specific applications, custom cable constructions are available with 600V, TC rated; aluminum or steel interlocked armor; CPE jacket or LSOH jacket; various jacket colors; alternate black and white color-coded pairs; multi-pair type B 22 AWG, PLTC-rated, individually and/or overall shielded; and multi-pair 18 AWG, TC-rated, individually and/or overall shielded.

About Fieldbus
Fieldbus is an all-digital, serial, two-way communications protocol that standardizes the interconnection of field devices at a communications rate of 31.25 kB/s. The field devices are made accessible to communication networks (running at 1 or 2.5 Mb/s), through use of linking devices. Because a simple twisted pair of wires can carry the signals between the field devices and the networks, Fieldbus users can reduce the amount of I/O and control equipment (due to distribution of control into the field devices), plus they can use fewer Intrinsically Safe (IS) barriers, cabinets, cables and connectors. And, since the wire pair can support multiple functions within a single device (such as diagnostics, control and auto error correction), the twisted pair cable becomes the integral part of a more efficient, more reliable, and more cost-effective industrial control system.

With FOUNDATION Fieldbus, end users have the freedom to implement tightly integrated digital control based on a unified system architecture and a high-speed backbone (HSE) for plant operations. This, in turn, removes the constraints on device and sub-system interoperability. Fieldbus has chosen Ethernet for HSE control backbone 100Mb/s transmissions.

Belden helps to drive industrial automation

Belden cables are being widely adopted by industrial users for the Process Industry and Factory Floor Automation. The company offers a range of Process Automation (PA) cables for use in instrumentation, regulation and control technologies. PROFIBUS PA technology allows safe transmission of data and power on the line. This enables the user to expand the possibilities of a state-of-the-art control system.

At a recent Press Briefing, Charles Ingham, Sales Director for Belden EMEA, provided an overview of the latest Belden products for industrial automation: “Belden cables have been widely installed in many key sectors, such as the oil & gas industry, chemical processing, paper & pulp manufacturing and processing; and the metals industry.

“Process Automation is used extensively by heavy industries who manufacture in continuous process. Over the years, pneumatic systems have migrated to 4- 20 mAmp systems and proprietary solutions; today they use open digital systems. The Belden range of Process Automation cable solutions offers cost, quality and performance benefits to everyone in the value chain – manufacturers, global companies with assets in multiple countries, main instrument builders (MIVs) and EPC contractors.

“Our customers are finding that they are benefiting from reduced maintenance costs, improved maintenance efficiency and a reduction in equipment life cycle costs.
The most significant potential to save money on is preventive instrument maintenance which is also the largest post on the costs side. Studies show that 63% of instrument maintenance labor results in no action taken; a large waste of resources.”

Process control
For industrial process control instruments, analog 4-20 mA and 10-50 mA current loops are commonly used for analog signaling, with 4 mA representing the lowest end of the range and 20 mA the highest. The key advantages of the current loop are that the accuracy of the signal is not affected by voltage drop in the interconnecting wiring, and that the loop can supply operating power to the device. Even if there is significant electrical resistance in the line, the current loop transmitter will maintain the proper current, up to its maximum voltage capability. The live-zero represented by 4 mA allows the receiving instrument to detect some failures of the loop, and also allows transmitter devices to be powered by the same current loop (called two-wire transmitters). Such instruments are used to measure pressure, temperature, flow, pH or other process variables. A current loop can also be used to control a valve positioner or other output actuator. An analog current loop can be converted to a voltage input with a precision resistor. Since input terminals of instruments may have one side of the current loop input tied to the chassis ground (earth), analog isolators may be required when connecting several devices in series.

Discrete automation
“In addition to process control, industrial automation also encompasses discrete automation or factory floor automation, in facilities where the production process is not continuous but in batches, typical examples are: automotive production and assembly plants and pharmaceutical and laboratory facilities.

“In these circumstances modern open bus-systems allow real-time processing, through having distributed intelligence in the field. Key Discrete Automation Protocols include Profibus, DeviceNet, ControlNet, Modbus, Interbus-S, Melsecnet and CC-Link. Each Protocol has its own characteristics and defines a specific cable type for communication.” Belden has the right cables to provide signal transmission solutions throughout industry. And we are continuing to invest. Some of our recently introduced products include:

7000x series of PROFIBUS PA cables for process automation
The Belden 7000x Series is aimed at process automation systems designed by Siemens for the processing industry. The range includes 2 PVC versions, an LSNH version and an LSNH/SWA (Steel Wire Armoured) version.

For enhanced mechanical protection and/or rodent protection, Steel Wire Armoured versions are available as are other jacket options such as PUR or Teflon or different armouring options such as steel wire braid.

Circuit integrity PLTC cables complying to UL and IEC standards
New Belden 300 V instrumentation cables meet the UL 2196 and IEC 60331 Standards for circuit integrity. This is very important in the processing industry to prevent loss of assets in the event of fire. These cables can be used in the emergency shutdown system as well as in the gas / fire detection systems.

The Standards prescribe the minimum time which the cables will have to withstand, UL 2196 2 hour rapid temperature rise fire starting at 538˚C (1000˚F) to 1010˚C (1850˚F) and IEC 60331 calls for a 3 hour burn test at 750˚C during which time the insulation is not allowed to fail.
These cables are standard halogen free and are suitable for in and outdoor applications. In addition, they can be used in hazardous areas zone 1 and 2, group II, as defined in IEC 60079-14 or class I or class II division 2 as per NEC 501.4 (b) or NEC 502.4 (b).
