Detailed explanation of common fiber jumper interface types

FC round with thread, commonly used in optical transceivers and other equipment

ST snap-on round type Commonly used in terminal box equipment

SC snap-on type Commonly used in fiber optic transceivers

PC microsphere grinding and polishing

APC is at an 8-degree angle and is ground and polished with microspheres

Fiber Patch Cord Interface Type

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.

①FC 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)

②SC type optical fiber jumper: the connector 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)

③ST-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 connectors are usually ST type. Often used in fiber optic distribution frames)

④LC-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)

⑤MT-RJ type optical fiber jumper: a square optical fiber connector with integrated transceiver, one dual-fiber transceiver integrated

ST, SC connector joints are often used in general networks. After the ST head is inserted, it is fixed with a bayonet in half a circle, but the disadvantage is that it is easy to break; the SC connector is directly inserted and unplugged, which is very convenient to use, but the disadvantage is that it is easy to fall out; It is reliable and dust-proof, but the disadvantage is that the installation time is slightly longer.

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.

Optical fiber modules: generally support hot swap, the optical fiber interface used by GBIC is mostly SC or ST type; SFP, namely: small package GBIC, the optical fiber used is LC type.
