CFA series – Singlemode
Adaptor Type (Female/Female) Attenuators
Description:
The adaptor type singlemode attenuators are used directly on the ends of fiberoptic jumpers prior to
installation in adapters. These attenuators provide a fixed level of attenuation and feature excellent
return loss. Low wavelength dependency determines them for using in WDM and DWDM transmission
systems. The CFA series attenuators are available in UPC or APC polish for SC, FC connectors and UPC
for ST connectors.
