Ando AQ8201-13B ECL Light Source Module

The Ando AQ8201-13B is an external cavity laser (ECL) light source module designed for optical testing and measurement in telecommunications, fiber optics, and research applications. This tunable laser source delivers stable, accurate optical output across the C-band and L-band spectrum, functioning as a plug-in module within the Ando AQ8200 Series Optical Test and Measurement System. The module occupies a single slot and integrates into compatible mainframes to support DWDM-related component evaluation and characterization.
