Amphenol's plug-style attenuator is compact in size, offers attenuation values from 0-20dB, and is available in LC, SC, and FC industry standard connector styles, either flat or angle polish.

This eliminates the scattering of light into the fiber cladding that could be reflected back from the connector interface.

With the short distance between connector end faces, the reflected light creates interference that in turn create the desired insertion loss variation as the wavelength changes.
