TIA568 Wiring Standards

How to decide which wiring pattern to use:

1. Does the job specification call out a wiring pattern?
2. Does the customer/end user have a preference for T568A or T568B?
3. Have patch panels already been purchased for the job? If so, they will probably be either T568A or T568B. The jacks should be wired to the same pattern as the panels.
4. Are you adding on to an existing wiring plant? If so, your new wiring should match the existing wiring.

If none of the factors above apply, either T568A or T568B may be used. It is important to ensure that the workstation connectors and the patch panels are wired to the same pattern. T568B is commonly used in commercial installations, while T568A is prevalent in residential installations.

CATV Tone and Probe Kit

Designed specifically for the CATV industry, the 402K will send tone through any passive device along the cable path. Now you can tone through splitters, directional couplers and traps. No more long delays trying to figure out non-tagged or mistagged cable drops. The 402K is simple to use and provides fast, accurate results. The transmitter and receiver are equipped with female F-connectors and the kit provides both audible and LED test and tone indications.

The addition of optional adapter test leads allows the 402K to be used on distribution cables as well as wire pairs or signal conductors. With its user defined tone output, up to four 402T Toner units can be used simultaneously for tracing multiple cables runs. As a continuity tester, the 402K provides both audible tone and LED display to indicate resistance levels. The unit will even identify the presence of AC or DC voltage on the cable under test.

The newly designed 402R receiver provides three methods of signal reception. Electrostatic pickup for non-terminated cables, electromagnetic pickup for terminated or shorted cables and direct connection when identifying in the presence of passive devices.

The 402K consists of one transmitter, one receiver, one male F-to-F connector adapter, one male F-to-alligator clip adapter cable and a 700C carrying case.
