Abstract

We propose a coordinated shared mesh restoration scheme at sub-wavelength connection level using integrated OTN switch and CDC-ROADM nodes. The optical layer flexibility of CDC-ROADMs in the integrated node enables additional OTN line card sharing and simulation results show up to 18% savings in OTN line cards compared to classic ROADMs.
