The AQ6370D is the latest iteration of the most popular Telecom class OSA from Yokogawa. It offers a versatile wavelength range of 600 nm to 1700 nm ideally suited for both Telecommunications and general-purpose applications. The unique free space input design allows testing of both DWDM class Singlemode and VCSEL sourced multi-mode fibers in one single model.

Newly added functions include data logging, gate sampling, resolution calibration, an advanced marker function, and an enhanced auto-sweep mode.
