DESCRIPTION
The laser diode driver consists of four sections: LD bias, back PD current monitor and temperature stabilizer, and voltage-to-current convertor which allows modulation up to 10MHz. It fits for 10-pin or 14-pin butterfly packaged Pump, DFB, SOA, SLED or equivalent. A Graphical user interface (GUI) running on PC make it very easy of use for green hand, and the UART serial comm. port is ideal for OEM or industrial test. The butterfly packaged laser is removable. It saves a lot if users want another power or wavelength of laser source. They only need to replace the LD.
