It is also used to connect telephony equipment, such as telephones and faxes, to telephone lines.

RJ48 cables are available in different lengths, from a few centimeters to several meters. They are usually made from copper or fiber optics.
These cables use a pair of twisted strands and an eight-pin modular plug.

The RJ48 uses the same plug and socket type as 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, but the RJ48 uses different wiring

There are two main types of RJ48 connectors : the RJ48 8P8C connector and the RJ48 6P6C connector.

• The RJ48 8P8C connector is the most common RJ48 connector. It has 8 contacts, or 4 twisted pairs.


• The RJ48 6P6C connector is a smaller version of the RJ48 8P8C connector. It has 6 contacts, or 3 twisted pairs.

The RJ48 8P8C connector is used for applications that require data transmission in all 4 twisted pairs, such as gigabit Ethernet networks.
The RJ48 6P6C connector is used for applications that require data transmission over 3 twisted pairs, such as 10/100 megabit Ethernet networks.

In addition to these two types of connectors, there are also shielded RJ48 connectors. These connectors are used for applications that require electromagnetic interference (EMI) protection.

There are 3 kinds of RJ48 cable :

An RJ48-C connector is a type of RJ48 connector that has an additional signaling pin. This extra pin is used for data transmission over an additional twisted pair.

The RJ48-C connector is used for applications that require data transmission over 5 twisted pairs, such as 10 gigabit Ethernet networks.

The RJ48-C connector is similar to the standard RJ48 connector, but it has an additional pin located next to pins 7 and 8. This pin is usually referred to as pin R1.

Pin R1 is used for data transmission on twisted pair 5. This twisted pair is typically used for transmitting synchronization data, such as the frame signal.

The RJ48-C connector is a relatively new type of connector. It is still little used, but it is becoming increasingly popular as 10 gigabit Ethernet networks become more common.

RJ48-S is a type of RJ48 connector that is shielded. The shield is a metal sheath that surrounds the connector contacts. Shielding helps protect the signal from electromagnetic interference (EMI).

RJ48-S connectors are used in applications that require EMI protection, such as gigabit Ethernet networks in industrial environments or medical facilities.

The shielding of the RJ48-S connector is usually grounded. This helps dissipate electromagnetic interference to the earth.

An RJ48-X connector is a type of RJ48 connector that has internal diodes that short-circuit pairs of strands when there is no cord connected. This avoids ground loops and improves overall network performance.

RJ48-X connectors are typically used in T1 or E1 networks, which use analog telephone lines to transmit digital data. Ground loops can form when devices that are not compatible with T1 or E1 networks are connected to the line, which can lead to performance issues. RJ48-X connectors help prevent these problems by shorting pairs of strands when there is no cord connected.

RJ48-X connectors are also used in Ethernet networks, but they are less common than in T1 or E1 networks. They can be used to improve overall network performance by preventing ground loops from forming.

Here are some advantages of RJ48-X connectors :

• They help prevent ground loops, which can improve overall network performance.


• They can be used in T1, E1 and Ethernet networks.


• They are relatively affordable.

Here are some disadvantages of RJ48-X connectors :

• They can be harder to find than standard RJ48 connectors.
  
• They may require specialized installation.
