FC Variable attenuator

Fiber Optic FC Type Variable Attenuator

With the excellent characteristics, Female to female variable fiber optic attenuators can be used in fiber optical telecommunication system and optical transmission system. These attenuators can be applied in FTTH, CATV, WAN, fiber optical sensor and metropolitan area network. They are often used as the testing equipment.



  • DWDM applications
  • Test & measurement
  • Optical sensors
  • Telecommunications applications


  • High quality ceramic core The application of Imported A – grade ceramic insert enable the product with high stability, good reliability , high transmission speed and low insertion loss.
  • Wide attenuation range 1dB to 30dB The FC attenuator are designed to give the accurate attenuation required by the connected device and are available in a wide range of attenuation levels.
  • Easy Installation The FC attenuator is designed for optical hardware to reduce the dB power, the plug type allows them to be used directly at the end of a patch cable, they also feature a dust cap on the tips for protection.
