FC/APC M/F Single mode Fiber Attenuator, Fixed Type

FC/APC Single mode Plug-in Fixed Fiber Optic Attenuator inserts FCA-terminated fiber directly into the back end of the attenuator connector to attenuate optical signals easily. The input to the attenuator has a 2.2mm wide keyed female connector, making it compatible with both narrow and wide-keyed male connectors. The plug-in design offers convenience and flexibility, allowing the attenuator to be easily plugged into and removed from fiber optic patch panels, adapters, or test equipment.
