Attenuator optic adopt mutlimode fiber 850nm wavelength, FC/PC connectors with 50/125um OM2 orange jacket. It is low insertion loss, high return loss and high precision attenuation value.
In line multimode attenuators typically use 50/125µm optical fiber, with connectors at both ends. The fiber diameter, cable length, and number of fiber cores can all be customized according to customer requirements.
