Fault-Tolerance Enhanced Design and Analyses for Optical Pyramid Data Center Network (OPMDC)

Abstract

This paper presents a fault-tolerance enhanced design and analyses for OPMDC[1]. Capacity-based analysis shows OPMDC accommodates 0.91-capacity under the worst-case single WSS-failure. Emulation analysis justifies that a 26dB-OSNR is retained under the worst-case three-WSS-failure scenario.
