VOA(Variable Optical Attenuator) are commonly used in fiber optic communications, either to reduce or control optical fiber power at a certain level . With the widely application of DWDM transmission system and EDFA in fiber optic communication, it’s even more important that optical network should be adjustable. Gain flattening or channel power equalization is vital in multi-optical signal transmission channel. It is also very important to take dynamic saturation control in optical receiver end. Optical network also needs to control other signals. All these controls make VOA an indispensable vital device in fiber optic communication.

SYOPTEK VOA(Variable Optical Attenuator) features low insertion loss, a wide attenuation range, a small package and easy operation. It can offer different attenuation range from 1 to 65dB, and is continually adjustable by a screw on the side of the attenuator frame.
