Device gets high data rates out of
copper wire
By compensating for signal distortion and removing noise, the QLx411G can achieve unprecedented speed over thinner gauge cable.
Quellan has released the QLx411G, an analogue device that can be embedded in copper cabling to yield 1.28 terabits per second in a single 1.75in high rack These "active cables" are terminated with the high-density QSFP connector, which achieves a density of 32 ports in a single 1RU rack, each running at 40Gbit/s

The NX2400 is billed as the system interconnect industry's first quad wideband noise canceller.
Comms chips use collaborative signal processing
Quellan's Lane Managers deliver interconnect at datarates of up to 6.25Gbit/s over copper cabling or system chassis.
In a live demonstration, Quellan ran the InfiniBand signalling protocol over these links at the new 40Gbit/s quad data rate (QDR) speed.
In order to retain backwards compatibility with this interface, the company also demonstrated QDR running in the standard microGiGaCN connector.
This throughput was enabled by embedding the company's Q:Active analogue technology into WL Gore and Associates' 28AWG cable assemblies.

Analogue devices make cables more intelligent
Quellan can now transform data centre cable interconnects from passive, nonactive devices to intelligent "roadways" for use in today's mega data centres.
By compensating for signal distortion and removing noise, this low-power analogue IC can achieve unprecedented speed over thinner gauge cable.
The QLx411G is Quellan's latest addition to the Quad Lane Extender product line, which also includes the QLx4300 for applications up to 3Gbit/s and the QLx4600 for applications up to 6Gbit/s.
This family of products share the same small 4 x 7mm signal integrity optimised package, making upgrading to higher data rates seamless for customers.
The product line also boasts low power and low latency.
The QLx411G supports InfiniBand, Ethernet, PCI Express, SAS and Fibre channel protocols in active cables, blade servers, line cards and switch cards.
Cabling today is a significant barrier to data centre efficiency - as measured by power, speed, density and latency.
The QLx411G delivers the lowest power, highest density and no additional latency, improving link efficiency.
"Quellan's technology promises to extend the reach of QDR InfiniBand links over copper cables, expanding the cost-effective 40Gbit/s interconnect ecosystem", said Thad Omura, Vice President of Product Marketing for Mellanox Technologies.
"With the production release of systems using multicore processors and PCIe Gen2, the data bottleneck has moved to the system I/O port".
"Low-cost, low-power cables combined with ConnectX IB 40 Gb/s HCAs will help bring balance to these high-performance compute and storage systems".
"Data centre cable management and power consumption are becoming increasingly critical", said Daryl Inniss, Vice President and Practice Leader, Components Division for Ovum-RHK.
"By removing cable impairments and attenuation with analogue silicon, thinner, lighter and longer cabling may be used".
"This reduces weight and increases room for airflow".
"Copper interconnects serve the vast majority of data centre links today", said Tony Stelliga, CEO of Quellan.
"By activating these passive cables with our analogue Q:Active technology, next-generation data centres can be built on dramatically thinner, faster and lower power interconnects".
