Multimodedigital Variable Optical Attenuator Attenuator Range Of
0~40 DB
The U8320 benchtop dimmable optical attenuator is
mainly used for channel balancing and power balancing in DWDM
systems, as well as optical measurement and applications of AWG
& PLC components, optical amplifiers and other general purpose
fibers. The U8320 benchtop optical attenuator is a high precision and wide
range optical power attenuator. Euwest Instruments offers a choice of single - and two-channel or
four-channel optical attenuators, as well as up to 32 - channel
host control solutions.Both the optical output and optical input interfaces (U8320) are
FC/PC ports.

The user asked the following questions:
1.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
2.What are the types of variable optical attenuators?
Basically, there are two types of optical variable attenuators:
stepwise variable attenuators and continuously variable
attenuators.
