25GHz 고밀도 파장 다중분할 필터용 반사형 위상보상 필터 설계

초록

Reflective phase compensator(RPC) filter provides a solution to the phase-dispersion problemof dense wavelength-division-multiplex(DWDM) filter when the data rate is 40 Gbits/s or greater. By use of the RPC filter to compensate for the excessive group-delay(GD)ripple of a DWDM filter, the GD ripple of the combined(DWDM+RPC)filter is well under the required 2.5ps
