FTTH Optical Grating Reflector 1650nm SC/APC reflector FBG
- Detail
Description:
1650nm fiber grating optical filter is the important components in the field of Optical communications link to detect. The principle is equivalent to a band-pass filter, which completely reflects light from 1643.5nm to 1656.5nm back (the return ratio is over 99.5%) and all other wavelengths of light pass through. Used in the field of communication can be separated communication light (C + L band) and detection of light, to prevent the detection of light through to the communication signal impaction, and can detect the return light at the control. All aspects of fiber grating indicators are stronger than the coating method.
