Tunable Laser WSL-110

Compact Tunable Laser

WSL-110
The WSL-110 is a compact and cost effective tunable laser source. Designed for use in fiber optic transmission testing, the WSL-110 can also be used for DWDM component evaluation and coherent communications testing.

 
 

Overview

C-band or L-band lasers are available, each covering a 38nm tuning range. The WSL-110 features Gridless tuning, allowing any wavelength to be accessed. An integrated wavelength locker ensures high wavelength accuracy and stability. This laser can be controlled either through the front panel or by using a GPIB interface, allowing full remote control and measurement automation.

 

Features

  • C-band or L-band tuning with high resolution
  • Settable to any wavelength
  • Fine tuning available with 1 MHz resolution
  • Narrow linewidth <100 kHz
  • High output power >+15 dBm
  • Integrated wavelength locker
  • One or two ports per unit

 

Applications

  • Fiber optic transmission testing
  • DWDM component testing
  • Testing & measurement
  • Local Oscillator for Coherent detection
