Grounding issues were also mitigated. another for decades, they have only been used in data Most importantly, UTP solutions are used as a baseline communications networks for just over 10 years. While interoperability media for the most prevalent protocols. data cables existed in different forms for several decades before UTP cables were predominantly used, they were In most cases a cabling solution is developed to support quickly replaced by UTP cables for several reasons. a faster transmission protocol. Today’s fastest protocol over UTP cable is 1000BaseT transmission. This is Coax and shielded cabling solutions, such as ThickNet, supported by both Category 5e and Category 6. ThinNet and IBM type 1, were very good cables for transmitting data within Local Area Networks (LANs). UTP AND THE END OF THE PROTOCOL WAR With the advent and proliferation of computer To better understand why UTP cable has evolved from networking technologies, more and more cables Category 1 to Category 6, we must first understand the occupied spaces “behind the scenes” where cables had primary driver ., data rate progression. In the early only existed for telecommunications purposes in the ‘90s a war was raging as to which protocol would past. Telecommunications closets were expanded to become the industry standard for LAN applications. allow for connectivity between networking devices ATM, Token Ring and Ethernet were all in contention. By (hubs), servers and workstation terminals. Data rates the mid ‘90s Ethernet had come out on top. It provided were on the order of 1 to 16Mbps and ran on a highly accessible technology with an outstanding cost proprietary cabling solutions. Several protocols existed basis that ultimately proved to provide the QoS needed for proprietary to somewhat standardised, networks, at the right price. In addition, the progression to such as Token Ring, ISDN and ATM. .
