What are the types and corresponding characteristics of fiber optic patch cords?


There are many types of fiber jumpers, FC, LC, SC and ST types, what are their corresponding characteristics? Take ZR Cable fiber as an example to briefly talk about it!


ZR Cable Fiber Patch Cord

1. FC type optical fiber jumper: the external strengthening method is a metal sleeve, and the fastening method is a turnbuckle. Generally used on the ODF side (the most used on the patch panel). The FC connector is generally used in telecommunication networks. There is a nut screwed onto the adapter. The advantage is that it is reliable and dust-proof. The disadvantage is that the installation time is slightly longer.


2. SC-type optical fiber jumper: the connector for connecting the GBIC optical module, its shell is rectangular, and the fastening method is the plug-and-pull type, which does not need to be rotated. (Most used on router switches). The SC connector is often used in general networks. The SC connector is directly plugged and unplugged, which is very convenient to use. The disadvantage is that it is easy to fall out.

3. ST-type optical fiber jumper: commonly used in optical fiber distribution frame, the outer shell is round, and the fastening method is turnbuckle. (For 10Base-F connections, the connector is usually ST type. Often used in fiber optic distribution frames). ST connector headers are commonly used in general networking. After the ST head is inserted, there is a bayonet to fix it in half a circle, but the disadvantage is that it is easy to break.


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


5.MT-RJ type fiber jumper: a square fiber optic connector with integrated transceiver, one dual fiber transceiver is integrated. The MTRJ type fiber patch cord consists of two high precision plastic molded connectors and fiber optic cables. The outer parts of the connector are precision plastic parts, including a push-pull plug-in clamping mechanism. Suitable for indoor applications in telecommunication and data network systems.
