Huawei mini sc adapters and ST and FC fiber optic connectors are early standards developed by different companies. They have the same effect and each has advantages and disadvantages. ST and Huawei mini sc adapters are often used in general networks. After the ST head is inserted, it is fixed with a bayonet semi-circle. The disadvantage is that it is easy to break. The Huawei mini sc adapter can be directly inserted and pulled out, which is very convenient to use, but the disadvantage is that it is easy to fall out. The advantage is that it is reliable and dustproof, and the disadvantage is that the installation time is slightly longer.

The MTRJ type fiber optic patch cord consists of two high-precision plastic molded connectors and fiber optic cables. The exterior of the connector is a precision plastic part, including a push-pull plug-in clamping mechanism. Suitable for indoor applications in telecommunication and data network systems.

① FC type fiber optic connector: The external strengthening method is metal sleeve, and the fastening method is turnbuckle. Generally used on the ODF side (mostly used on the patch panel)

② huawei mini sc adapter: the connector for connecting the GBIC optical module, the outer shell is rectangular, and the fastening method is the plug-in pin type, which does not need to be rotated. (most commonly used in router switches)

③ ST-type optical fiber connector: commonly used in optical fiber distribution frame, the outer shell is round, and the fastening method is turnbuckle. (For 10Base-F connections, the connectors are usually ST type. Often used in fiber optic patch panels)

④ LC-type fiber optic connector: a connector for connecting SFP modules, made with a modular jack (RJ) latch mechanism, which is easy to operate. (commonly used by routers)

⑤ MT-RJ: A square optical fiber connector with integrated transceiver, one end is a dual-fiber transceiver.
