Tunable Laser Evaluation Circuit Board                                                                   To Top

TLDB-B


 

Key Features

         Wavelength control electronics

         High-speed modulation driver (optional)

         USB interface

         Mounting base and heatsink for tunable TOSA

         PC based control software

 

 

 

 

Applications

         TOSA evaluation

         Tunable laser source

         Test and measurement

         Other laboratory applications

 

The tunable laser evaluation circuit board is designed for evaluation of tunable laser TOSA. It includes 3 current controls for the laser wavelength and output power, a TEC controller and an USB interface for PC communication. A high speed modulation driver is also available. The on-board mount provides easy access for TOSA mounting and evaluation. Typical tunable TOSA module has a LC/PC socket output. The evaluation module requires a single 5V DC power supply.

In combination with a tunable TOSA, this device can also be used as a tunable laser source for test and measurement, and other laboratory applications.
