SC UPC/APC Variable Optical Attenuator (VOA)
Fiber optic attenuator is used for reducing the power of the light in the fiber optic network.
Variable fiber optic attenuator could help simulate distance or actual attenuation in the fiber optic testing work by inserting a calibrated attenuation into the link. Important parameters of variable fiber attenuator include its insertion loss, reflection loss and attenuation range.
Features:
High Precise attenuation value
Perfect environmental stability and reliability
Low additional loss
Flawless end face
Wide attenuation range (variable)
Material:
Housing: Nickel Plated Brass
Sleeve: Ceramic Zirconia
Application:
Fiber optical telecommunication system
FTTH, CATV, LAN
Subscriber loop
Fiber optical sensor
Testing equipment
