Description
Overview
GAOTek Low Loss SM Fixed Optic Attenuator 20 dB (In – Line Metal Housing) is a passive component used to reduce the power level of an optical signal with an attenuation level upto 20 dB. It is mainly used in an optical fiber. GAOTek Fixed optical attenuator has attenuation levels ranging from 1 dB to 30 dB, with standard and premium tolerances and custom configurations. It is durable with a simple and reliable structure and low back reflection. It has high power endurance and is wavelength independent.
