The Anritsu MN924C is a calibrated variable optical attenuator engineered for precise optical signal power control in fiber optic communication systems. It employs combined step and continuous attenuation mechanisms to deliver highly accurate adjustments across single-mode fiber networks. Designed for operation at 1.3 µm and 1.55 µm wavelengths, the MN924C provides the control resolution required in laboratory and field testing environments. Note: This model was discontinued in July 2004; the MN9605C is the recommended replacement.
