Abstract :
We investigated crosstalk of FSK supervisory channel superimposed on a 112 Gbps DP-QPSK caused by pass-band narrowing effect in CNCG ROADM network. We estimated maximum number of ROADM nodes and frequency misalignment tolerance between main signal and center frequency of WSS pass-band that the FSK light label technique could support.
