Types of Network Connectors

Spread the love

We will discuss about types of Network Connectors in Data Communication. Network Connector is a device that terminates a segment of cabling or provides a point of entry for networking devices such as computers.

There are many types of network connectors.

1. USB (Universal Serial Bus)

A single USB port is a type of network connector and can be used to connect up to 127 peripheral devices. USB 1.1 standard supports data transfer rates of 12 Mbps, while USB 2.0 (Also referred to as Hi-Speed USB) specification defines a new High-speed transfer rate of 480 Mb/sec.

2. RJ-11 (Registered Jack)

RJ-11 is the common connector for plugging a telephone into the wall and the handset into the telephone. It is also called modular connector wired for one plain old telephone service line (using two wires out of six available positions) and is found in most homes and offices in most countries of the world for single-line telephones.

3. RJ-45 Network Connector (Registered Jack)

The RJ-45 is also a type of network connector is an eight-wire connector. It used to connect computers to a local area network (LAN). RJ-45s can be used to connect some types of telephone equipment.

This cable connector that is found on almost all UTP and STP cables. The “45” simply refers to the number of the interface standard..

There are two types of RJ-45.

This type of cable is typically used for direct computer-to-computer connections.

4. FC-Type Network Connector

F connector is a type of RF connector commonly used for cable and universally for satellite television. It has good performance up to 2 GHz. it uses the center wire of the coaxial cable as the pin of the male connector.

F-type connector is a form of coax cable connector that is widely used with domestic television equipment. F connector is cheap and can perform to frequencies in excess of 2 GHz.

5. ST (Straight Tip)

Fiber network segments always require two fiber cables: one for transmitting data, and one for receiving. The straight-tip(ST)connector is used for connecting cable to networking devices. It uses a bayonet locking system and is more re liable than SC

MT-RJ is a new connector which has the same size as RJ45

The ST connect was developed by AT&T.  Europeans use a round ST connector (Straight Tip) instead.

ST uses a bayonet fitment rather than a screw thread.

6. SC (square connector)

 SC was developed by the laboratories at Nippon Telegraph and Telephone (NTT). In North America, most cables use a square SC connector (Subscriber Connector or Standard Connector). The SC connector is also available in a Duplex configuration.

The SC is ideally suited for data communication and telecoms applications. SC connectors provide for accurate alignment via their ceramic ferrules.

7. Fiber LC (Local Connector)

These connectors are also types of network connectors that are used for single-mode and multimode fiber-optic cables. LC was designed as a push-pull connector. FC connectors offer extremely precise positioning of the fiber-optic cable.  LC is its small size.

The LC has good performance and is highly favored for single mode.

8.MT-RJ (Mechanical Transfer Registered Jack)

MT-RJ connectors are used with single-mode and multimode fiber-optic cables. The MT-RJ is commonly used for networking applications.Its size is slightly smaller than a standard phone jack and just as easy to connect and disconnect.

MT-RJ connectors are constructed with a plastic housing and provide for accurate alignment via their metal guide pins and plastic ferrules.
