Raysung OTDR FBG reflector uses FBG technology to reflect OTDR test signal (1645~1655nm or 1615~1635nm).
With wide bandwidth and low insertion loss, Raysung FBG reflectors are ideal to create high reflectance at the termination of a passive optical network (PON) without disturbing traffic. Comparing with the traditional reflector with thin film technology, FBG reflector has the advantage of very high reflectance at the test signal, very low insertion loss at the traffic signal very sharp reflection bandwidth edge, and very long lifetime.

Note:
1. IL(dB)= -10log10(Output Power/Input Power) ;
2. RL(dB)= -10log10(Reflected Power/Input Power);
3. To measure the RL at reflect band, the light should be injected from the female side of the reflector;
