The MN95D optical variable attenuator passes an optical signal from a light emitting element through an optical fiber via a lens through an attenuating filter to reduce it to an appropriate light power output. It is a reflection type using metallic film and is used in the 1.3 µm band. The MN95D can be varied continuously and in steps. Features Wide attenuation range: 0 to 60 dB Metallic film filters assure a wide range of usable wavelengths and stable accuracy. Prevention of multiple reflection. Small and lightweight.
