Fiber Optical Attenuator LC-APC Optical Fiber Attenuator
Classification by interface
According to the type of port, it can be divided into the following
categories:
(1) SC optical fiber attenuator: applied to SC optical fiber
interface, it looks very similar to RJ-45 interface, but the SC
interface looks more flat. The obvious difference is the contact
inside. If it is 8 thin copper contacts, it is RJ-45 interface, and
if it is a copper column, it is SC optical fiber interface.
(2) LC optical fiber attenuator: used for LC optical fiber
interface and connector connecting SFP module. It is made of
modular jack (RJ) latch mechanism with convenient operation.
(commonly used by routers)
(3) FC optical fiber attenuator: applied to FC optical fiber
interface. The external reinforcement method is metal sleeve and
the fastening method is turnbuckle. Generally used on ODF side
(most used on distribution frame)
(4) St optical fiber attenuator: it is applied to st optical fiber
interface and is commonly used in optical fiber distribution frame.
The shell is circular and the fastening method is turnbuckle. (for
10base-f connection, the connector is usually st type. It is
commonly used for optical fiber distribution frame)
