SDDC series DFBLaser driver board, compact design, internal integration of LD driver, and Tec high-precision temperature control, communication industry and industrial laser industry two different pin definitions of DFB laser, is the ideal driver of DFB laser.The drive board LD drives part of the current to 2a, has analog quantity and modulation signal interface, and the analog quantity modulation speed can be from 100kHz to CW. The design accuracy of LD temperature control part can reach 0.01 degree.All parameters of the board can be factory set according to the customer's requirements, including rated current, default set temperature, andTECRated current and voltage.

production characteristics

WeRising and falling edge of stage

    No ripple current, no overshoot

    High efficiency, no special heat dissipation for the board itself (DFB laser needs to be fixed on the heat sink)

    Compact design, easy integration

 

Recommended applications

    Fiber laser

    Semiconductor test

Communication laser
