Telecom Connectors

Telecom connectors can be found at the end of telecom cables, used to transmit data and provide telephony services.

There are, however, a few variations within RJ telecom connectors. The RJ11 connectors are the most common type used for home phones, RJ12 connectors are typically used in system phones, and RJ14 connections are used in systems with two telephone lines.


Fibre-optic telecom connectors

Fibre optic telecom cables are a new entry in the world of telecoms, used by many telephone carriers because of their increased bandwidth. Standard RJ connectors will not work with these cables, and you can use specialist fibre-optic connectors instead.
