Fiber Bragg Grating

Athermal package Fiber Bragg Grating wavelength filter telecommunication Description Fiber Bragg grating are wildly used as wavelength filter at telecommunication aspects. While its central-wavelength is sensitive to temperate changes from environment. The Athermal package is with special technology making the central wavelength without changes according to outside environment temperature changes. Application LAN local area network Trunk Line Network Dense Wavelength Division

Phase Shift Fiber Grating Central Wavelength 1550nm Reflectivity 90% PM Fiber Phase Shift Fiber Grating DWDM 1550nm Fabry-Perot Lower Loss Phase Shift Fiber Grating Description: Phase Shift Fiber Grating means: through leading in Refractive Index moudulation sudden changes On the optical Fiber Bragg Grating certain place, it generate two FBGs with fixed phase shift sudden changes at this place. The two FBGs similar choose Fabry-Perot and allow light with resonant wavelength

Distributed Optical Fiber Vibration Sensing System 50km Submarine Cable Damage Monitoring Distributed Optical Fiber Vibration Monitoring System DVS Description Optical Fiber Vibration Sensing System is based on the optical fiber RAYLEIGH scattering principle. It uses the SMF to be the slightly vibration sensing part and also cooperate with the optical fiber vibration main detection controller, the system can real time detect the vibration signal of the optical fiber. Through

Distributed Optical Fiber Cable Temperature Monitoring System DTS Description: DTS (Distributed Temperature Sensing System) adopts the advanced feature that OTDR technology and RAMAN distributed light is sensitive to temperature, which can detect the temperature changes at different locations along the optical fiber, to realize the real distribution measurement. It has 4, 8, 16 channels system. DTS not only can do fire alarm on time, but also can locate the fire area place.
