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).
