Fiber Optic FBG Reflector ONU Grating Fiber Optic Reflector SC APC
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.
- Grating embedded in the fiber, free from environmental pollution;
- High reliability, long life expectancy;
- Reflectance is high for bands that need to be blocked (above 99.5%), close to total reflection;
- The wavelength of the reflection band is controlled accurately (1643.5nm ~ 1656.5nm)
- In the bandpass edge of the transition zone is very narrow (less than 2nm), this area is all-pass;
- Using the standard common adapter structure, easy connection;
Pass 1310+1550 nm and Stop 1650nm.

SC/UPC Male & SC/UPC Female
(1) ORL(dB) = -10 log 10(Reflected Power/ Input Power) [dB];
(2) IL(dB) = -10 log 10(Output Power/ Input Power) [dB];
(3) To measure the Return Loss of reflect band, the light of 1650nm should be injected from the female side of reflector.
Q: The History of our factory?
A: In 2000, Yuda entered the communications industry and began to make adapters. It accumulated funds to invest in jumper production in 2006, and increased the optical splitter workshop in 2009. Yuda won the national high-tech industry in 2013, and sold over 15 million US dollars in 2015, and began to explore foreign markets.
