Fixed Attenuators

RUR Fixed Attenuators are designed for the purpose of reducing optical power levels in a network to match the receiver’s requirements. Our range of high performance attenuators are designed to give accurate attenuation over a wide range of wavelengths. Our attenuators are presented with a plug type configuration; allowing for ease of use and functionality. Straight out of the box, these attenuators allow for direct connection to a fibre patch cord, for insertion into the relevant RUR adapter..
