  DWDM FBG

Description
In DWDM system, the high channel isolation is necessary to avoid cross talk between channels. The DWDM Gratings are applied in disjunctive or insertion pathway to increase or decrease the filter. Idealphotonics offers 50/100/200GHz gratings spacing ITU grid, it has a flat top, high isolation, low insertion loss and low polarization dependent loss characteristics. The DWDM gratings are available individually packaged or be combined with multiple filters as a multiplexer/demultiplexer
