Tunable Laser WSL-100

Compact Tunable Laser

The WSL-100 is a compact and cost effective tunable laser source for use in WDM systems and optical measurement applications. This laser is tuned over C-band or L-band, covering a 38nm tuning range with 25 or 50 GHz channel spacing to the ITU-T grid. An internal wavelength locker provides high wavelength accuracy and stability. This laser can be controlled either by using the buttons on the front panel or by using GPIB interface. GPIB control with industry standard SCPI command set provides fully remote and automated solution for the customized measurement.
