In the optical fiber jumper, it can be divided into 4 types according to the connector, SC, ST, FC, LC. How to distinguish fiber jumpers is to distinguish them from each other according to their different interfaces. ZR Fiber will explore with you below.
How to distinguish fiber jumpers
1. SC connector
The shell of the SC connector is rectangular and is connected with the SC coupler, which is connected by direct plugging and unplugging without rotation.
Advantages: direct plug, easy to use. Using engineering plastics, high temperature resistance, not easy to oxidize.
Disadvantage: The connector is easy to fall out when used for a long time.
SC card connection type (the most used on router switches).
2. ST connector
The ST connector shell is round with bayonet, connected to the ST coupler, and needs to be rotated about 90° when used.
Advantages: The connection is tight and not easy to fall off.
Disadvantages: Since the connector needs to be rotated for half a turn after being inserted and fixed by the bayonet, it is easy to break.
ST clip-on type is often used in optical fiber distribution frame.
3. FC connector
The FC connector is similar to the ST connector. How to distinguish this fiber optic patch cord? , the shape is round, but the FC connector is threaded, and it is connected to the FC coupler by rotating.
Advantages: Reliable connection, dust-proof.
Disadvantages: Due to the need to rotate, it brings inconvenience to the installation, so the installation time is slightly longer.
FC round with thread (most used on patch panels).
4. LC connector
The LC connector is similar to the SC connector, but smaller than the SC connector. The LC connector is used to connect SFP fiber optic modules and is made with an easy-to-operate modular jack (RJ) latch mechanism.
Commonly used LC jumpers are connected to optical fibers and optical modules, so they are generally LC-SC or LC-FC, and most of them are used in pairs, rarely a single LC jumper.
The LC card connection type is often used in routers.
