SELCO IT Structured Cabling/Horizontal Wiring Standards

SELCO has adopted the ANSI/TIA 568 standards for Ethernet structured cabling for all enterprise systems and networks.  Although not an enforceable building or wiring code, the ANSI (American National Standards Institute) TIA (Telecommunications Industry Association) 568 standard is the defining document for all commercial Ethernet cabling and has been so since its inception in 1991.  Tested and proven, these standards provide the highest degree of reliable and dependable wiring.

The TIA 568 standards were developed in parallel with ISO 11801.  They define the terms we use to describe system components, cable segment length, establish connection sequences, etc.  For example, we use CAT6 cable for Ethernet wiring; the term CAT6 refers to the ISO definition Category-6 which defines the type of cable, the wire gauge, the color sequence, the number of connectors, and how the connectors are twisted together within the wire jacket. By consistently following these rules we significantly raise the reliability of our network and aid in any future diagnostics or troubleshooting.

These standards have increased in significance given the fact that it’s more than just computers that use our wiring plant.  Telephones, wireless AP’s and cameras also use our structured cabling topology.  Furthermore, we are in some cases deploying POE (Power Over Ethernet) devices, which carry power as well as data.  While there may be other possible ways to run, terminate and connect cables that may still “work”, we do not recommend diverting from the TIA 568 or ISO 11801 standards for structured cabling.  It is the standard that provides the highest level of reliability.

Our standards are not part of the wiring code, but this is what we require for all structured cabling installs.  They are best practices, industry standard, and what we need to ensure good service.
