The JDS Uniphase MVOA (MAP-VOA) is a motorized variable optical attenuator module engineered for integration into the MAP platform chassis. It delivers precise, fine-grained control of optical power levels across C- and L-band wavelengths, supporting automated attenuation in laboratory and production test environments. The module uses stepper motor and filter-based attenuation technology to achieve low insertion loss and minimal optical impairments across its 70 dB dynamic range.
