20DB LC Fixed Fiber Optical Attenuator Easy To Operate Green

Fiber Optical Attenuator Flange LC-LC Fixed Light Attenuation Adapter 1-20DB

Classified by interface
According to the type of port, it can be divided into the following categories:

SC optical fiber attenuator: applied to SC optical fiber interface, it looks very similar to RJ-45 interface, but the SC interface is flatter, the obvious difference is the contact piece inside, if it is 8 thin copper contacts, then It is an RJ-45 interface, if it is a copper column, it is an SC optical fiber interface.

LC optical fiber attenuator: used in LC optical fiber interface, the connector to connect SFP module, it is made by the easy-to-operate modular jack (RJ) latch mechanism. (Routers are commonly used)

FC optical fiber attenuator: applied to FC optical fiber interface, the external strengthening method is a metal sleeve, and the fastening method is a turnbuckle. Generally used on the ODF side (most used on the distribution frame)

ST optical fiber attenuator: applied to ST optical fiber interface, often used in optical fiber distribution frame, the shell is round, and the fastening method is turnbuckle. (For 10Base-F connection, the connector is usually ST type. Often used in optical fiber distribution frames)
