Ando AQ4320A Tunable Laser (S+C band)

The Ando AQ4320A Variable Wavelength Optical Source is a high-precision tunable laser designed for WDM communication and optical amplifier testing, offering a wavelength range of 1480 to 1580 nm with continuous sweep functionality and high wavelength resolution of 0.001 nm. With a typical optical output level of +10 dBm at 1550 nm, excellent side mode suppression ratio (SMSR) of 70dB (AQ4320B), and narrow linewidth, it ensures stable, uninterrupted performance even during wavelength and output adjustments. Its built-in wavelength calibration and remote control capabilities via GPIB or RS-232C make it ideal for automated test setups, enabling accurate evaluation of fiber amplifiers, optical components, and D-WDM systems.Download AQ4320A Series User Manual
