Berk-Tek Introduces Highest Performing, Smallest Diameter Category 6A Cable

New Holland, PA – February 10, 2020 – Berk-Tek, a Nexans Company and leading manufacturer of  network infrastructure solutions, introduces LANmarkTM-SST, a new high-performing, small-diameter Category 6A cable. 

LANmark-SST is the smallest diameter Category 6A CMP UTP construction available, at 0.25 inches. This reduced diameter offers better flexibility, optimized cable management, and improved tray-fill ratio than the average Category 6A cable, making it ideal for high-density installations. 

LANmark-SST has a specially designed insulated metallic isolation wrap that provides superior heat management and noise-cancelling performance. The insulated design prevents electrical energy from running along the shield, eliminating the need for grounding. 

“This newest cable from Berk-Tek offers the outstanding signal isolation and excellent high-PoE performance that our customers need, making it a great choice for high-power, high-bandwidth applications like 802.11ac wireless, HD video, and IP security,” says Brian Simmons, Copper Product Manager for Berk-Tek. He adds, “At the same time, the smaller diameter is a great option for high-density installations. And we’re able to offer all these benefits at a cost-effective price point.”  

LANmark-SST is available for immediate order.
