When used in the field of communication, the Fiber Reflector can separate the communication light from the detection light, prevent the detection light from passing through and thus affect the communication signal.
The fiber optic reflector has the advantages of low insertion loss, high reflectivity, convenient installation, etc., and is an ideal optical device for network link monitoring；It is widely used in PON network, OTDR testing, central computer room testing, FTTX and other fields.
FTTH optical grating reflector 1650nm 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.
Fiber optic reflector, also known as fiber Bragg grating filter, is usually installed in the front end of optical network ONU. Combined with OTDR equipment, optical link point-to-point (PTP) or point-to-multi-point (PTMP) network monitoring can be realized, and network abnormalities can be reflected quickly and accurately.
Common types include adapter type and pigtail type. We provide different types of fiber optic reflector, such as SC Female-Male type, LC Female-Male type, SC/APC pigtail type and LC/APC pigtail type.
The fiber (FBG) reflector meets the working environment of-20~70℃, with an average of more than 500~1000 insertion and removal tests, with stable performance and reliable quality.
