Four-Pair Horizontal
Four-pair horizontal cables primarily utilize the 8P8C modular jack or plug.
8P8C Modular Jack 8P8C Plug
In most scenarios, cabling is terminated on jacks and the plugs come pre-installed on patch cords to
complete the connection. However, field-installable plugs are available and, if used, should be installed
based on the manufacturer’s instructions. Shielded connectors should be used with U/FTP or F/UTP cable.
TIA/EIA-568-B recognizes two pin/pair assignments for four-pair cable: T568A and T568B, with
T568A as the primary and T568B if required to accommodate certain cabling systems. In practice
T568A is used primarily in residential and government applications (the US government only
recognizes T568A), while T568B is used primarily in commercial applications. The important point
is that only one method be used within the network.

Acceptable methods of identifying the “white” conductor of a pair include band marking,
longitudinal striping and ColorTip®.
Band marking consists of banding each insulated conductor with the color of the mating conductor
(in the blue/white pair, the blue conductor would have white bands and the white conductor would
have blue bands).
