SC FTTH Optical Grating Reflector/ Optical Grating Filter/Fiber Bragg Grating FBG Filter
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.
Features:
- 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;
Function:
Pass 1310+1550 nm and Stop 1650nm.
RoHS compliance

Note:
(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, FIBCONET started our adapters business at first and accumulated
funds, then we started producing jumpers in 2006. In 2009 We developed
the splitter workshop. The sales volume exceeded 15 million US dollars
in 2015. In the same year, we began to explore foreign markets.
Q:What's your advantage products?
A:optic fiber PLC splitter, patch cord, pigtail, connector and adaptor
Q:What insert loss (IL)Value we can reach?
A:Below 0.1db,generally 0.2db is enough for the market.
Q:What kind of package you usually applied in?
A:We usually use carton, but it also can be customized
Q:Warranty policy?
A: This is our fiber equipments warranty notice:
