LC-UPC 1-30dB Optical Fiber Attenuator single mode Multimode

Fiber Optic Attenuator LC-UPC 1-30dB 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)
