The principle of optical fiber communication is to use the total reflection of light from an optically dense medium to an optically sparser medium. Optical fiber jumpers are used to make jumpers from equipment to optical fiber cabling links, which involve interfaces, usually SC, ST, LC, FC and other types.
What is a fiber patch cord?
Optical fiber jumper connectors are a problem that users must consider when purchasing optical fiber jumpers. Understanding the meaning of various optical fiber jumper connectors can help users find the products they want faster.
FC type fiber jumper
The external reinforcement method is a metal sleeve, and the fastening method is a turnbuckle. 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. Generally used on the ODF side (the most used on the patch panel, and also mostly used for optical transceivers)
SC type fiber patch cord
The connector for connecting the GBIC optical module has a rectangular shell, and the fastening method is a plug-and-pull type, which does not need to be rotated. The SC connector is directly plugged and unplugged, which is very convenient to use, but the disadvantage is that it is easy to fall out (the most used on routers and switches)
ST type fiber patch cord
After the ST head is inserted, it is fixed by a bayonet half-circle and is fixed. (For 10Base-F connections, the connectors are usually ST type.
LC fiber patch cord
A connector for connecting SFP modules, constructed with an easy-to-use modular jack (RJ) latch mechanism. (SFP optical module default LC interface)
MT-RJ type fiber jumper
A square fiber optic connector with integrated transceiver, one dual-fiber transceiver is integrated. MTRJ type fiber optic 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.
