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.
