Like RJ45, RJ61 has 8 contacts RJ61 The RJ61 connector, also known as the "Registered Jack 61", is a type of modular connector used mainly in telephone applications. It is designed to support multiple phone lines on a single twisted-pair cable. Physical Characteristics : The RJ61 connector is very similar to the RJ45 RJ45 RJ45 - Registered Jack 45 - is also called an Ethernet cable. This cable can be straight or crossed depending on its use, its connections follow precise color codes. It is the most common cable for network connections for example to the Internet. This type of cable has 8 pins of electrical connections. Its connector is called 8P8C connector (8 positions and 8 electrical contacts). connector, it usually has 8 contacts, which is similar to the standard RJ45 RJ45 RJ45 - Registered Jack 45 - is also called an Ethernet cable. This cable can be straight or crossed depending on its use, its connections follow precise color codes. It is the most common cable for network connections for example to the Internet. This type of cable has 8 pins of electrical connections. Its connector is called 8P8C connector (8 positions and 8 electrical contacts). connector. The RJ61 connector is equipped with 8 metal contacts arranged in two rows of 4 contacts each. These contacts are usually gold-plated to ensure reliable electrical conductivity and a long service life. Each metal contact is designed to fit into a corresponding slot on the RJ61 socket, ensuring a secure and stable connection. Wiring Diagram : The internal wiring of the RJ61 connector is designed to support multiple phone lines. Each pair of contacts is dedicated to a separate phone line. Unlike the RJ45 RJ45 RJ45 - Registered Jack 45 - is also called an Ethernet cable. This cable can be straight or crossed depending on its use, its connections follow precise color codes. It is the most common cable for network connections for example to the Internet. This type of cable has 8 pins of electrical connections. Its connector is called 8P8C connector (8 positions and 8 electrical contacts). connector used in Ethernet networks, the RJ61 connector's wiring diagram is not compatible with Ethernet standards. With the advent of structured cabling systems and TIA/EIA-568 (now ANSI/TIA-568) conventions, the RJ61 cabling model fell into disuse. The T568A and T568B standards are used in place of the RJ61 so that a single cabling standard in a facility can be used for both voice and data. Cabling RJ61 is a physical interface often used to terminate twisted pair type cables. This is one of the recorded sockets and uses an eight-position, eight-conductor modular connector (8P8C). This pinout is intended for multi-line telephone use only; The RJ61 is not suitable for use with high-speed data, as the pins of pairs 3 and 4 are too far apart for high signaling frequencies. The T1 lines use another wiring for the same connector, designated RJ48 RJ48 An RJ48 cable is used to connect telecommunications equipment, such as modems, routers, and switches, to local area networks (LANs) or wide area networks (WANs). It is also used to connect telephony equipment, such as telephones and faxes, to telephone lines. . Twisted-pair Ethernet (10BASE-T, 100BASE-TX, and 1000BASE-T) also uses different cabling for the same connector, either T568A or T568B. The RJ48 RJ48 An RJ48 cable is used to connect telecommunications equipment, such as modems, routers, and switches, to local area networks (LANs) or wide area networks (WANs). It is also used to connect telephony equipment, such as telephones and faxes, to telephone lines. , T568A, and T568B are all designed to keep the pins close to each other for pairs 3 and 4. The 8-core "satin silver" flat cable traditionally used with 4-line analogue telephones and RJ61 sockets is also not suitable for use with high-speed data. Twisted-pair cabling should be used with RJ48 RJ48 An RJ48 cable is used to connect telecommunications equipment, such as modems, routers, and switches, to local area networks (LANs) or wide area networks (WANs). It is also used to connect telephony equipment, such as telephones and faxes, to telephone lines. , T568A, and T568B. Note that the data twisted-pair patch cable used with the above three data standards does not directly replace the RJ61 cable, as RJ61 pairs 3 and 4 would be split between different twisted pairs of patch cable, causing crosstalk between voice lines 3 and 4 that may be noticeable for long patch cables.
