Item No.: Y-FO-OA-025
in-line variable optical attenuators can be used in fiber optical telecommunication system and optical transmission system. These attenuators can be applied in FTTH, CATV, LAN, fiber optical sensor and subscriber loop.
Description Parameters Company profile Related Product
SC-SC Variable in-line Optical Attenuators (Adjustable in-line optical attenuator) are used to permit dynamic control of optical
power levels in a fiber. It uses for precisely balancing the signal strengths in fiber circuits or balancing an optical signal
when evaluating the dynamic range of the measurement system. With turning the knob by hand, attenuation value can
be set up to 55dB.


It can be applied to adjust power level of signal in the optical communication at the output of light sources, E/O

converters and for the linear or dynamic range of power meter. Furthermore, they can the used in optical amplifier

systems to balance the gain across the different operating wavelengths.
