The Exfo IQ-1203 is a four-channel optical power meter that enables simultaneous measurement of optical power levels across independent fiber optic channels. Part of the IQ-1200 series, it integrates with the IQ-203 mainframe and IQ-206 expansion units to form a modular optical test platform. Each of the four independent photodetectors supports multi-channel monitoring and multi-component testing, supplemented by a virtual channel for expanded data acquisition. The meter operates across the 800 nm to 1700 nm wavelength range and delivers measurement accuracy of ±0.25 dB with linearity of ±0.02 dB and resolution to 0.01 dB.
