27dBm 1650nm Wavelength SC APC Fiber Optical FBG Reflector
Product Description
The 1650nm fiber grating filter is an important device for communication link detection in the optical field. The principle is equivalent to a bandpass filter that completely reflects back light from 1643.5nm to 1656.5 nm (return ratio exceeds 99.5%), and all other wavelengths of light pass. In the field of communication, the communication light (C+L band) can be separated from the detection light to prevent the detection light from passing through and affect the communication signal, and the return light can be detected at the control end. All aspects of fiber grating are stronger than coating methods.
