SC Female to Female variable attenautor

Share to:


Optical attenuator is a passive device used to reduce the power level of an optical signal. It is generally used in single-mode long-haul applications to prevent optical overload at the receiver. Optical attenuator is widely used in CWDM&DWDM, CATV systems, data center networks, test equipment and other high-power applications. Though its applications range widely, attenuators are most commonly used for test and measurement, optical sensors, and telecommunications applications.

SC Female to female variable attenuators from OMC offer defined control of optical signals in both integrated and add-on products.



  1. 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.


  1. Wide attenuation range 1dB to 30dB

The SC attenuator from OMC are designed to give the accurate attenuation required by the connected device and are available in a wide range of attenuation levels.


  1. Easy Installation

The SC attenuator from OMC 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.
