  SC LC ST FC Fiber Optic Attenuator


1. Description

Optical attenuators are commonly used in fiber optic communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels. Sharp bends stress optic fibers and can cause losses. If a received signal is too strong a temporary fix is to wrap the cable around a pencil until the desired level of attenuation is achieved.


2. Application

EDFA, DWDM, Long-haul

Wide-Area networks

Telecommunication networks

Gigabit applications (ATM, Ethernet)
