LC Plug-IN Fixed Fiber Optic Attenuator (SM & MM)

Fiber optic attenuator is able to reduce optical power and limit the optical power received by the photodetector within the limits of the optical receiver.
We offer a wide range of fiber optic attenuators, SC attenuator, FC attenuator, LC attenuator, ST attenuator, etc.
Fixed Fiber Optic Attenuator has different attenuation values from 1dB~30dB, 5dB attenuator, 10dB attenuator, 15dB attenuator, 20dB attenuator, 30dB attenuator for example.
Fixed Fiber optic attenuator has female to female adapter type attenuator and male to female plug-in type attenuator.

Female to female LC Fiber Optic Attenuator is able to couple from LC connector to LC connector, while male to female LC Fiber Optic Attenuator from LC adapter to LC connector. The combination of attenuation film in female to female LC attenuator or attenuation fiber in male to female LC attenuator and precision molded polymer/metal housing provides reliable and stable optical attenuation performance.
