TC-DFB Series 852nm DFB Laser Source

 

The TC-DFB series 852nm DFB laser source adopts high-performance DFB laser chips from abroad, uniquely designed ATC and APC circuits, and isolation control, ensuring extremely high power and wavelength stability. This light source is mainly used in the field of clock frequency measurement, which can be used with an electro-optic modulator to load time frequency signals and transmit them through optical fibers; It can also be used for measuring optical devices in the 850nm wavelength range, such as testing the responsiveness or response time of high-speed Si PIN/APD photodetectors, CMOS, CCD, and other devices.
