About this deal

The Rj9 has a different shape than the Rj11. It is rectangular, while the Rj11 is a square-shaped connector. This wiring pattern is for multi-line analog telephone use only; RJ61 is unsuitable for use with high-speed data because the pins for pairs 3 and 4 are too widely spaced for high signaling frequencies. T1 lines use another wiring for the same connector, designated RJ48. Ethernet over twisted pair ( 10BASE-T, 100BASE-TX and 1000BASE-T) also uses different wiring for the same connector, either T568A or T568B. RJ48, T568A, and T568B are all designed to keep both wires of each pair close together.

Cables made to the BT specification typically feature paired 0.5mm insulated copper conductors, but the number can vary hugely, from as little as 2 to as many as 200. The insulating sheath is normally PVC, but you may also see: Trulove, James (December 19, 2005), LAN wiring (3rded.), McGraw-Hill Professional, ISBN 0-07-145975-8 . A modular connector is a type of electrical connector for cords and cables of electronic devices and appliances, such as in computer networking, telecommunication equipment, and audio headsets. This color scheme originates in the (withdrawn) national standard DIN 47100. The scheme shown here is the correct color code for interfacing with the RJ connector standards. Motorola uses the 10-pin connector as a microphone connector in several of their mobile radio product lines. [ citation needed]

Please note:

RJ48 is used for T1 and ISDN termination, local-area data channels, and subrate digital services. It uses the eight-position modular connector (8P8C). Mac Plus Keyboard Cable", Syrinx, UK: Megadon, ...the cable is the same as the telephone cable that connects handsets to the phone, unfortunately [...] this type of cable and pretty much any type of pre manufactured cable [...] is wired wrong for the Mac Plus. Under no circumstances should you use this cable as you will damage your keyboard and/or your Mac! RJ11 utilizes a standard 6P2C connector for a standard phone association. It possibly utilizes a 6P4C connector when low-voltage power is needed to ship off the marker light of the phone.

Retrieved 3 August 2021.The important fact to consider about Rj9 is that the RJ 9 isn’t a connector you will run over occasionally. It is often signified as the RJ10 or RJ22, and it likewise has a unique setup type. Both types of 8P8C plugs are available in shielded and unshielded varieties for different attenuation tolerances as needed. Shielded plugs are more expensive and require shielded cable, but have a lower attenuation, and may reduce electromagnetic interference. The micro ribbon connector, first made by Amphenol, that is used in the RJ21 interface, has also been used to connect Ethernet ports in bulk from a switch with 50-pin ports to a Cat-5 rated patch panel, or between two patch panels. A cable with a 50-pin connector on one end can support six fully wired 8P8C connectors or Ethernet ports on a patch panel with one spare pair. Alternatively, only the necessary pairs for 10/100 Ethernet can be wired allowing twelve Ethernet ports with a single spare pair.
