Optical fiber connector is connector connected to the optical module. Some people will mistakenly think that the optical fiber connectors of GBIC and SFP modules are the same, but they are not. The SFP module is connected to the LC fiber optic connector, and the GBIC is connected to the SC fiber optic connector.
ST, SC, FC fiber optic connectors are standards developed by different companies in the early days, and they have the same effect and have their own advantages and disadvantages.
ST and SC connector connectors are often used in general networks. After the ST head is inserted, it has a bayonet to fix it half a circle, the disadvantage is that it is easy to break; the SC connector is directly plugged in and out, it is very convenient to use, the disadvantage is that it is easy to fall out; the FC connector is generally used in telecommunication networks, and there is a screw cap screwed to the adapter. It is reliable and dustproof. The disadvantage is that the installation time is slightly longer.
Several commonly used optical fiber connectors are described in detail:
1. FC type optical fiber connector: The external reinforcement method is a metal sleeve, and the fastening method is a turnbuckle. Generally used on the ODF side (most used on the distribution frame)
2. SC-type optical fiber connector: the connector for connecting GBIC optical module, its shell is rectangular, and the fastening method is a plug-in latch type without rotation. (Most used on router switches)
3.ST-type optical fiber connector: commonly used in optical fiber distribution frame, the shell is round, and the fastening method is turnbuckle. (For 10Base-F connection, the connector is usually ST type. Often used in optical fiber distribution frames)
4. LC-type optical fiber connector: the connector for connecting SFP modules, which is made of a modular jack (RJ) latch mechanism that is easy to operate. (Routers are commonly used)
5.MT-RJ: a square optical fiber connector with transceiver integrated, one end of dual fiber transceiver integrated
