The FHA2 series is a compact, portable variable optical attenuator. The attenuation level is displayed on the device's screen, making it easy to check at a glance. certification and routine maintenance as well as in lab environment. Interchangeable FC/PC, SC/PC connectors. Bulk attenuators can operate based on several principles, such as filter wheels with neutral density filters, rotated. varies in attenuation along its length and a high precision stepper motor is used to move the filter to the requested attenuation level. for achieving a suitable signal level for a data receiver in a telecom system. It supports two wavelengths of 1310/1550nm and allows attenuation settings in increments of 1dB or 0. It is expected to be useful. Fibre optic attenuators, also called optical attenuators, are passive devices used to reduce the power level of an optical signal.
