1.1   ProductFunction

Fiber Bragg Grating (FBG) filter at 1650 nmis an important device for communication link detection in opticalcommunication field. The principle is equivalent to a band-pass filter, whichcompletely reflects the light from 1643.5 to 1656.5 nm (the return ratio ismore than 99.5%) and passes through all other wavelengths. In the field ofcommunication, the communication light (C+L band) can be separated from thedetection light to prevent the detection light from passing through, thusaffecting the communication signal. At the same time, the return light can bedetected at the control end. Its advantages are precise control, stable operationand long service life.

Pass1310+1550 nm and Stop 1650nm.

2、OPTIC SPECIFICATION

Note:

(*)ORL(dB) = -10 log 10(Reflected Power/ Input Power) [dB];

(**)IL(dB)= -10 log 10(Output Power/ Input Power) [dB];

(***)To measure the Return Loss of reflect band, the light of 1650nmshould be injected from the female side of reflector.

(****)This product is bidirectionalreflector, the optical signal can be input on both sides of the item
