Single Mode VOA Attenuator Large Dynamic Attenuation Range Of 0 ~ 40 DB
The U8310 bench dimmable attenuator is mainly used for channel balancing, power balancing, gain slope and power adjustment of DWDM system. It can provide a large dynamic attenuation range of 0 ~ 40 dB continuously adjustable. It has the advantages of superior performance, small size, fast start-up and low price. The model is not single, single mode or multiple mode can be assembled as four-channel, the model is: U8314 / U8324, the performance index is the same as that of single channel.The 8310 has a relatively stable attenuation range of 0 ~ 40 dB.

The user asked 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 (Fig. 4.3).
