Second Decade: 1986-1995 Tightly Twisted LAN cables Year of Innovation: 1987-1988 Nearly 30 years ago, an innovative group of cable designers within the copper cabling division of AT&T (now part of CommScope) discovered that twisting conductors together very tightly would maintain the mechanical helical structure and minimize conductor nesting in cables. This dramatically improved the level of isolation between the pairs without necessitating shielding. The unshielded twisted pair cables became known as “data grade UTP” and were standardized as Category 5e in global standards for use in local area networks (LAN) and other applications. Our cable designers and manufacturing teams have continually advanced twisted pair technology to support ever higher data rates.

This Allen Telecom development established repeaters as standard elements in wireless networks. It generated more than $500 million in revenue and made Allen Telecom, which bought Decibel, Mikom, Tekmar, Forem and eventually was bought by Andrew.
