Alfafonet singlemode and multimode attenuators are used in commucination 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 wavelenghts. The plug type configuration allows them to be used directly on the end of patch cord, which in turn can insert directly into an adaptor.

Features - Plug-in type - Adapter type - In-line type - Available in FC, SC, LC, ST and MU connector styles with UPC or APC finish. - Attenuator provide ultra-low return loss and are available from 1 dB to 30 dB. - Accurate attenuation - Ultra low back reflection - Broad wavelenght band - Flat response over a wavelenght range - Environmentally stable		Applications - Telecommunications networks - Fiber optic sensors - Test and measurement - CATV - LAN and WAN - FTTX
