Accelerator. demonstrates robust transmission on various industry standard cables at SuperComm 2002 Accelerant Networks Inc., the leading developer of intelligent high-speed communication transceivers, today demonstrates the industry's first transceiver (TRANSmitter reCEIVER) An electronic device or circuit that transmits and receives analog or digital signals. It comes in many forms; for example, a transponder on a satellite, a network adapter in the computer or the circuits in a cellphone. solution operating at up to 6.25 Gb/s per port over 20 meters of various types of industry standard cables. The demonstration showcases an unprecedented level of copper cable performance achieved through optimal integration of continuously adaptive equalization A transmission technique that dynamically adjusts its modulation method based on the quality of the line. , multi-level signaling, scrambling, and auto-negotiation provided by Accelerant's unique WILDPHYR(TM) transceiver technology. These capabilities will enable system architects to more efficiently and quickly develop and deploy high-performance stacking and chassis-to-chassis interconnects. At SuperComm 2002, the company is demonstrating robust and cost effective copper interconnect solutions achieving 10 Gb/s and 40 Gb/s of payloads over 4 pairs and 16 pairs of copper wires respectively. Until now, interconnect solutions have relied on expensive optical links or copper links limited in speed and reach. The Accelerant solution delivers double the bandwidth on a given channel and extends the reach over 4 times on various standard copper cables. "Accelerant's copper interconnect solutions have significantly boosted copper cable bandwidth, while alleviating the signal integrity problems known at higher speed transmissions," said Paul Nahi, president and CEO (1) (Chief Executive Officer) The highest individual in command of an organization.

"We have optimized the WILDPHYR(TM) technology to enable the industry's highest performance copper cabling interconnects." DEMONSTRATION AT SUPERCOMM 2002 At SuperComm 2002, Accelerant is showcasing its WILDPHYR(TM) transceiver technology applied to solve the performance bottlenecks of cable interconnects, as well as highlighting the groundbreaking performance of its AN5000 and AN5500 backplane An interconnecting device that has sockets for printed circuit boards to plug into. Passive and Active Although resistors may be used, a "passive" backplane adds no processing in the circuit. transceivers. The cable demonstration is based on Accelerant's cable evaluation and test platform that integrates several industry standard connectors and cable assemblies of various lengths, to showcase low-cost, short-reach payloads from 10 to 40 Gb/s. The backplane transceiver, demonstrated over a number of production backplanes, shows qualitative and quantitative measurements at up to 6.25 Gb/s per serial link. ADAPTING TO CABLE LENGTH VARIATIONS The key to optimal performance on various cable lengths is the ability to continuously equalize e·qual·ize v. e·qual·ized, e·qual·iz·ing, e·qual·iz·es v.tr. 1.

Accelerant's solution uses adaptive equalization to pick one solution out of millions of possible equalizer settings for each cable assembly. That means that systems in which up to 20M of cable have been characterized will automatically adapt when a user plugs in a much shorter cable, alleviating any need for the system to know what cables are attached. Accelerant's on-chip adaptive equalizer An adaptive equalizer is a filter that adaptively updates its coefficients in order to track a time-varying communication channel. It is frequently used with coherent modulations such as phase shift keying in wireless communications, mitigating the effects of multipath propagation and adjusts the amplitude amplitude (ăm`plĭt  d'), in physics, maximum displacement from a zero value or rest position. and the equalizer coefficients continuously, based on the unique and varying environmental and electrical conditions, during the operation without user intervention. The adaptive equalizer is field proven at up to 6.25 Gb/s of error-free operation. ALLEVIATING INTERFERENCE AND NOISE The Accelerant solution achieves the highest noise immunity of any product targeted at copper cabling installations.

Accelerant's technology offers high data throughput at controlled and regulated emission and susceptibility levels in order to comply with existing guidelines. ANALYSIS OF ATTACHED CABLE PLANT Accelerant's technology couples onboard Refers to a chip or other hardware component that is directly attached to the printed circuit board (motherboard). Contrast with offboard. See inboard. adaptive equalization and transparent communication between the transmitter and receiver with proprietary software tools. This creates the foundation for the most essential analysis of quality and characteristics of the attached cable plant, without the need for external hardware and software tools. Interconnect margin analysis produces a quantitative metric on the robustness of each channel. In addition, Accelerant's software includes full margin analysis of a channel, including BER (1) (Basic Encoding Rules) A set of encoding rules for ASN.1 notation, which is a method for defining data structures.

The software tool automatically detects compromised links and faults that are due to poor connections or misconnections. WILDPHYR(TM) TECHNOLOGY The continuously adaptive equalization, multi-level signaling, and auto-negotiation of WILDPHYR(TM) transceiver technology provides the communication intelligence that optimizes performance, improves ease-of-design, and increases reliability in new and existing networking equipment. Because Accelerant Networks' WILDPHYR(TM) technology solves the bottleneck A lessening of throughput. It often refers to networks that are overloaded, which is caused by the inability of the hardware and transmission lines to support the traffic. It can also refer to a mismatch inside the computer where slower-speed peripheral buses and devices prevent the CPU problem in backplanes and cable interconnects, it opens up more options for developers of networking equipment than ever before.
