Fiber Optic Attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave
form itself. The basic types of optical attenuators are fixed and variable, and are designed to be used with various kinds of fiber
optic connectors. The attenuators can be female to female or male to female.
Female to male SC fiber optic attenuator and female to female SC fiber optic attenuator are available. They fit typical 1310nm and
1550nm single mode fiber applications. Attenuation range is from 1dB to 20dB. We supply both SC UPC fiber optic attenuator and
SC APC fiber optic attenuator. The SC fiber optic attenuators operation wavelength range is 1240nm to 1620nm.
