Crosstalk accumulation performance comparison among different OXC architecture

摘要

Optical crosstalk imposes a major limit to the practical implementation of optical cross-connects (OXCs). Inraband crosstalk contributions in three types of OXCs topologies based on the dilated Benes (DB) and generally modified dilated Benes (GMDB) networks are investigated and compared. Numerical simulation and experimental results confirm that OXCs based on GMDB networks can eliminate intraband crosstalk influence effectively compared with OXCs based on DB networks.
