QP-DFB series 852nm DFB laser light source

QP-DFB series 852nm DFB laser light source uses foreign high-performance DFB laser chip, unique design of the ATC and APC circuit and isolation control, so it can ensure a very high power and wavelength stability. This product is mainly used in the field of clock frequency measurement, and it can be used with electro-optical modulator, loading time frequency signals. Signal is The signal is transmitted through the fiber. It also can be used in 850nm band optical device measurement, such as high-speed Si-PIN / APD photodetector , the tests of CMOS, CCD and other devices responsiveness or response time.

Features:
  • Built-in optical isolator
  • Module package and desktop package are optional
Applications:
  • 850nmoptical fiber system
  • Optical frequency comb
  • Spectral analysis
  • Time and frequency measurement
  • Visible light detector test system
