光纤连接器通常用于在路由光信号时终端需要灵活的地方。

1. Bionic Connector

The now obsolete Bionic connector was one of the first connectors employed in fiber optic communications links. This connector can be easily identified by the tapering sleeve that fixes on to the fiber optic connector. The narrowing end enables the sleeve to be located on the connector properly. The connection is secured by the guided rings that are provided complete with caps. These fit over the ferrule and screw onto the sleeve that is threaded.

2. Standard Connector(SC)

Simple, rugged and low cost, SC connectors use a ceramic ferrule to deliver accurate alignment of the SMF. The SC connector comes with a locking tab that enables push on / pull off operation. At the time of writing the most popular choice for such equipment like Fiber Multiplexers, GPON and EPON ONU’s, Fiber Media Converters and more.

3. Ferrule Core Connector(FC)


Although the FC connector was widely used in fiber optic networks until of late, its use is dwindling fast. This connector uses a threaded container and a position locatable notch to achieve exact locating of the SMF in relation to the receiver and the optical source. Once the connector is installed, its position is maintained with total precision. FC connector is pretty common choice for example in Video over Fiber Transmission Equipment.

4. Bayonet Nut Connector(ST)

The ST connector’s keyed bayonet design is similar to that of a BNC (Bayonet Nut Connector or Bayonet Neill-Concelman) connector. The connector is used widely for MMF and SMF FOC and is extremely easy to use. The ST connector is manufactured in two versions – the ST and the ST-II. Both types are keyed and spring loaded, and use a “push-in and twist” mechanism.

In some cases, if Multimode type cable is required, some of our customers order RCA audio over fiber converter, with ST connectors

5. SMA Connector

The obsolete SMA connector was the forerunner to the ST connector which we discussed above.. This connector was eventually replaced by the ST, and later by SC connectors.

6. Lucent Connector (LC)

The Lucent Connector, sometimes referred to as the Little Connector, is a small form factor FOC that uses a 1.25 mm ferrule. There are 3 different types of LC connectors:

  1. Single Mode LC APC
  2. Single Mode LC UPC
  3. Multi-Mode LC UPC
