The Anritsu ML93A Optical Power Meter paired with the MA98A Optical Power Sensor provides direct detection measurement of fiber optic signals across the 0.75 to 1.8 µm wavelength range. The system combines a germanium photodiode sensor with a precision display unit, delivering 0.01 dB resolution and ±5% accuracy at standard operating wavelengths. Designed for field installation, maintenance, and network troubleshooting, this compact instrument measures optical power in Watts, dBm, or dB (REL) modes with a four-digit display and analog meter.
