Small round diameter Cat 6a-compliant 10G UTP cable

September 7, 2007 -- Berk-Tek has introduced its LANmark-10G2 UTP cable, which features a small round outside diameter of .300" nominal.

September 7, 2007 -- Berk-Tek, a Nexans company, has introduced its LANmark-10G2 UTP cable, which features a small round outside diameter of .300" nominal.

According to the company, the cable is designed and guaranteed to meet the electrical component requirements of proposed TIA-568-B.2-10 standard for Augmented Category 6 supporting IEEE 10GBASE-T out to 100 meters.

The cable was engineered using a patent-pending design that incorporates four twisted pairs cabled with three monofilament elements to ensure a completely round cross-section. The company says the cable's unique geometry and pair configuration creates a significantly reduced cable diameter, while preserving the alien crosstalk performance of the original LANmark-10G.

"The biggest challenge in producing a copper UTP cable for 10 Gigabit applications is eliminating the alien crosstalk between neighboring cables. The key is to keep the pair with the longest lay length furthest from adjacent cables," explains Frederic Jean, senior product development engineer at Berk-Tek. "Our patent-pending design is an industry breakthrough that allows us to accomplish this and reduce the overall cable size."

"The new LANmark-10G2 UTP cable provides significant space savings in horizontal and vertical pathways and simplifies installation over other 10G cables on the market," adds Jim Frey, copper product manager at Berk-Tek. "With a small round design and reduced bend radius, high-density installations are easier and the smaller size allows for better airflow in the pathway, which is a major concern in data centers, where 10G is most often deployed."

The LANmark-10G2 cable is part of the NetClear GTX 10 Gigabit UTP channel solution from Berk-Tek and Ortronics/Legrand. Together with the Ortronics Clarity10G UTP TracJack modular outlets, patch panels and patch cords, NetClear GTX is guaranteed to meet or exceed all TIA 568-B.2-10 component and channel requirements, according to the companies.

"When tested to Category 6A internal permanent link or channel requirements, using a NetClear approved handheld tester, the NetClear GTX system is guaranteed to support 10GBASE-T 10 Gigabit transmission for a full 25 years," notes Todd Harpel, Director of Marketing. "No further alien crosstalk testing is required if the system is properly installed according to the latest standards and current NetClear data sheet requirements."
