Fiber Optical Isolator
The optical fiber isolator is a dual - port non - reciprocal optical passive device. It can attenuate the optical signal transmitted along the forward direction very little while attenuate the optical signal transmitted along the opposite direction very much, constituting a one-way path of light. When the laser and the transmission fiber are indirectly inserted into the optical isolator, the reflected light generated from the distal end face of the fiber and the interface of the fiber connector in the line can be effectively suppressed to return to the laser, so as to ensure the stability of the laser working state and reduce the noise caused by the reflected light in the system. This is more important for high - rate optical fiber communication systems. There are many kinds of optical isolators. Shenzhen Xingbo Technology can provide you with various types of optical isolators, mainly block optical isolators, all-fiber optical isolators, integrated optical waveguide optical isolators and optical isolators independent of polarization, etc. Its function is to prevent the backward transmission light in the optical path due to various reasons on the light source and optical path system produced by the bad influence.
