Micropol Attenuator LCU

Micropol Attenuator LCU

A fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself.

Our attenuators are GR 910 certified by Experior Laboratories (SC APC and LC UPC). The attenuator has been mechanical tested that includes 5,000-hour environmental tests. The solid body at the LC attenuator has a stronger design for greater mechanical strength. With a compact housing, the LC has reduced length and allows a wide range of usage including the existing PON Network.
