SC/APC Fiber Optic Fixed Attenuator, Single Mode, 1250nm to 1600nm, Plug Type, 3dB attenuation.
This high performance attenuator is designed to give accurate attenuation over a wide range of wavelengths. The plug type configuration allows it to be used directly on the end of a patch cord, which in turn can insert directly into an adaptor or SFP socket.
Optical attenuators are commonly used in fibre optical communications, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmit and receive margins.
If a received signal is too strong these attenuators are used to protect the optical interface of the devices.
