SC Fiber Optic Attenuator

The SC fiber optic attenuator adopts pull-push design to ensure convenient connection and disconnection as well as stable structure. Mostly in rectangular or square shape, it is easy to use, and features high attenuation accuracy and good repeatability.


Designed according to RoHS, IEC, and GR-326 standards, the product is an ideal choice to control the power level of an optical signal in fiber optic communications system, so as to avoid signal distortion caused by over high optical power. It is commonly found in fiber optic distribution frames and distribution boxes, telecommunications networks, local area network, wide area network, and fiber to the home network systems.
