A modular 8-wire jack and/or connector for use with copper cable having four twisted pairs, typically unshielded twisted pair Category 3 or Category 5. Used for telephony, ISDN, 10Base-T and 100Base-T4 Ethernets, 100VG-AnyLAN, and Token Ring LANs.
A USOC code identifying an 8-pin modular plug or jack used with unshielded twisted pair cable. Officially, an RJ-45 connector is a telephone connector designed for voice grade circuits only. RJ-45 type connectors with better signal handling characteristics are called 8-pin connectors in most standards documents, though most people continue to use the RJ-45 name for all 8-pin connectors.
(Registered Jack 45) is a standard connector for the ends of a Category 5 network cable. Though it is similar in apperance to a phone plug (RJ-11), it has 8 wires rather than 6, and is slightly wider. ROFL Rolling On Floor, Laughing rootkit
A serial connector which looks very much like a standard telephone connector, except it houses eight wires instead of four. RJ-45s are not typically found on computers or normal serial equipment, but because they are so small they are often used on devices such as terminal servers that have many ports.
Registered Jack-45. The connector that is used to terminate Ethernet cable (i.e. Cat 5, Cat 5e, or Cat 6). RJ-45 is a modular connector that has eight pins. However, only 4 pins (pin 1, 2, 3, 6) are used for transmit and receive. They are as follows: Pin 1 : Tx + (Transmit +) Pin 2 : Tx - (Transmit -) Pin 3 : Rx + (Receive +) Pin 6 : Rx - (Receive -) To identify pin number, look at an RJ-45 connector at the end of a Cat 5 cable with the tab on the bottom and the pins on the top, pin 8 is the rightmost and pin 1 is the leftmost. See picture of RJ-45 and RJ-11 jacks. Also see Cat 5.
RJ-45 connectors look a bit like a standard phone connector but are twice as wide (with eight wires). RJ-45s are used for hooking up computers to local area networks (LANs) or for phones with lots of lines.
A standard modular connector that supports up to four pair of copper wires. RJ45 connectors are used with 10BaseT cabling for connecting computers, DSL modems and routers, and other networked equipment to a hub on an Ethernet network.
Standard connectors used in Ethernet networks. They appear similar to standard RJ-11 telephone connectors. However, RJ-45 connectors can have up to eight wires, whereas telephone connectors have only four. close
A slightly larger (8 pin) version of the RJ-11. Used to connect computers to local area networks (Ethernet, 10 base T or 100 base T) and also used for the connection (demarc) point of an ISDN or T1 line. Note: The pin-out is DIFFERENT for BRI, PRI, and T1; beware.
The RJ-45 is a single-line jack for digital transmission over ordinary phone wire, either untwisted or twisted. The interface has eight pins or positions. Usually used for network connections, such as 10BaseT or Ethernet.
RJ-45 is the 8-conductor version of an RJ-11. It looks like a regular modular phone connector, only it's wider. You need to use RJ-45 for Ethernet, because the connection standard puts the Ethernet on some of the outer connectors not in RJ-11. RJ-11 plugs will fit into an RJ-45 socket, but because the plastic plug is smaller, some of the contacts will get bend back a little.
Registered Jacks, sometimes described as RJ-XX. Series of telephone connection interfaces that are registered with the FCC. The most common telephone jack is the RJ-11 jack, which can have six conductors but usually is implemented with four. The RJ-11 jack is likely to be the jack that your household or office phones are plugged into from the ordinary "untwisted" wire that people are most familiar with. The RJ-45 is a single-line jack for digital transmission over ordinary phone wire, either untwisted or twisted. The interface has eight pins or positions.
