Description

Fiber Bragg grating filters (reflectors) are devices that achieve a mirror-like reflection function for specific wavelengths through gratings. The principle is equivalent to a bandpass filter, featuring extremely high reflection efficiency and excellent wavelength cutoff characteristics.

Features

High stability and reliability, easy to adapt to structural connections, low insertion loss, operates in non-communication bands
Tolerant to extreme environments of -40℃ to 85℃
Insertion and removal life > 500 times
Reflectivity > 99.5% (typical value @ 1650nm) Insertion loss < 0.3dB, ensuring efficient signal transmission and reducing test errors
Compliant with RoHS regulations

Applications

FTTH/FTTB
PON System
Detection and location of ODN failure points as well as analysis of the causes
Precisely calculate the echo loss value of each reflection event at the end of each ONU branch.
