Attenuators are used in communication systems to reduce optical power launched onto the photo detector. These high performance devices are designed to give accurate attenuation over a wide range of wavelengths. The plug type configuration allows them to be used directly on the end of a patch cord, which in turn can insert directly into an adapter.
Available in FC, SC and LC (short form factor) connector styles with UPC or APC finish and ST and MU connector styles with UPC finish, attenuators providing ultra-low return loss and are available from 0 dB to 30 dB in 1 dB increments.
