Description：

This optical source is designed especially for DTS system of optical fiber sensor Raman test temperature.Sending command by PC soft or outside MPU to read all the parameters inside the module(such as temperature, current, power, pulse width and so on).Getting the operating condition inside the module andsetting the parameters such as pulse width, repetition frequency, peak power as well.
External modulation is optional: For the DTS system with code mode operating, out modulation is optional.

According to the trigger signal of the module is sent into to decide if produce the optical pulse. The pulse width and peak power still can be set freely by PC.Excellent pulse circuit: Unique short pulse optical drive circuit is employed to ensure the laser to keep excellent transient performance and safety. It makes the pulse rising or falling edge to 3n.
Complete product series: 1550nm band which is employed in long distant and 915nm, 940nm, 975nm band which is short distant and low cost are provided. Single mode SMF-28, 50/125, 62.5/125, multiple modes 105/125 is optional to adapt different systems.
