The fiber bragg grating reflector is a low-cost specific band reflector mounted on the optical network unit (ONU) side. It can reflect light pulses (1650 +/- 5 nm) from the OTDR on the fiber line terminal (OLT) side nearly 100%, while the working bands of the passive optical network (PON) are transmitted normally. The OTDR can determine whether the fiber line is normal by detecting the signal reflected by the fiber grating reflector. When the reflected signal is lower than the normal value, the line loss is too large; when the reflection value is 0, the optical fiber line is broken.Therefore, we can maintain the fiber line in time by the real-time monitoring of the fiber line.Its performance indicators have an impact on communication lines, insertion loss affects the loss of optical fiber lines, and return loss affects the signal quality of communication lines. It is very important to select a filter with excellent indicators.

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;

Application:

Detection and maintenance of Passive Optical Network lines (applied to FTTx).
