Monoline Single Pair Balun - RJ11 3 cord pins 3 4 to RJ45 jack 10BaseT

Cat 5 e cable is an enhanced version of Cat 5 that adds specifications for far end crosstalk. It was formally defined in 2001 as the TIA/EIA-568-B standard, which no longer recognizes the original Cat 5 specification. Although 1000BASE-T was designed for use with Cat 5 cable, the tighter specifications associated with Cat 5e cable and connectors make it an excellent choice for use with 1000BASE-T.

The 8 Position 8 Contact (8P8C) (often called RJ45) plugs and sockets are most regularly used as an ethernet connector. 8P8C connectors are typically used to terminate twisted pair cable.

A patch cable or patch cord (sometimes patchcable or patchcord) is an electrical or optical cable, used to connect ("patch-in") one electronic or optical device to another for signal routing. Devices of different types (ie: a switch connected to a computer, or switch to router) are connected with patch cords. Patch cords are usually produced in many different colours so as to be easily distinguishable, and are relatively short, perhaps no longer than two metres. Types of patch cords include microphone cables, headphone extension cables, XLR connector, RCA connector and 1/4" TRS connector cables (as well as modular ethernet cables), and thicker, hose-like cords (snake cable) used to carry video or amplified signals. However, patch cords typically only refer to those short ones used with patch panels.

RJ11 is a physical interface often used for terminating telephone wires. It is probably the most familiar of the registered jacks, being used for single line POTS telephone jacks in most homes across the world.Cables sold as RJ11 are nearly always 6P4C (six position, four conductor), with four wires running to a central junction box. Two of its six possible contact positions connect tip and ring and the other two conductors are then unused. 6P2C and 6P6C can also be found in stores.
