The MN924C and MN9605C are high-precision optical attenuators designed for use with single mode optical fibers. A combined step attenuator and continuous attenuator permit highly accurate attenuation adjustment.
The MN9605C has PC-type optical connectors, so that internally reflected light is thoroughly suppressed. It is precisely constructed for single-mode fiber use and can be used as a highly accurate 65 dB variable attenuator.
MD924C is now obsolete, so MN9605C should be purchased as an alternate model.
