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)
