Simulation and Experimental Studies of DWDM Nonlinear Phase/Polarization/Power Crosstalk Between DFOS and Communication Channels in 27.6-Tb/s 800ZR Metro Network
Abstract
We comprehensively analyze the fiber nonlinearity crosstalks between DAS and communication channels through numerical results and 40 x 800-Gb/s 90-km experimental demonstration. Our findings indicate that conventional pulse-based DAS is unsuitable for in-band DWDM coexistence system, whereas pulse-compression DAS shows negligible penalties with legacy coherent transceivers.
