Other users also ask the following questions:
1.What is a variable optical attenuator?
A variable optical attenuator is used to trim a fiber's optical signal power levels. Applications include leveling the power exiting an optical amplifier across a fiber's spectrum, and protecting a photodetector at a receiver from being overwhelmed by too strong a signal.
2.What does an attenuator do for fiber?
Attenuators are used to temporarily add a calibrated amount of signal loss in order to test the power level margins in a fiber optic communication system. In the second case, attenuators are permanently installed in a fiber optic communication link to properly match transmitter and receiver optical signal levels.
