This unit
The Exfo IQ-1643 is a 4-channel high-speed optical power meter engineered for simultaneous measurement across multiple fiber-optic signals. Built around InGaAs photodetectors, it delivers measurement ranges from 9 dBm to −85 dBm with ±0.25 dB accuracy and ±0.02 dB uncertainty. The instrument achieves stabilization times as fast as 1 ms in manual gain mode and up to 4096 samples per second in triggered high-speed acquisitions, supporting dynamic range up to 95 dB. Its low polarization-dependent response ensures reliable measurements across varying polarization states.
