Belden CDT Networking launched the Belden IBDN System 10GX UTP cabling system for 10 Gigabit Ethernet service this week at the BICSI Winter Conference in Orlando.
The 10GX system’s cable is based around Belden’s SpiralFleX, which consists of two element — a filler twisted around four cable pairs and internal cross-web design.
These features increase and randomize the distance between a cable and its neighboring cables, resulting in improved Alien crosstalk coupling and Return Loss channel characteristics, Belden said.
According to the company, the major technological challenges in designing a 10G system are to reduce Alien crosstalk to a level that is about 15dB, or 30 times lower than the ANEXT performance for 1000BASE-T at 100 meters.
Secondarily, a top-performing 10G system should provide controlled performance during high frequency operation up to a minimum of 500 MHz.
"Today, 10 Gigabit Ethernet Structured Cabling Systems have proven viable for data centers, campus backbones and other current applications," it said.
"They also provide the extended bandwidth and reliable power distribution required to handle new and emerging applications for which there is growing demand.
"Clearly, greater bandwidth in 10G service will be increasingly required as voice, data and video networks converge onto a single infrastructure."
