Abstract

Agile all optical cross-connect (OXC) switches currently use an architecture in which regenerators and transceivers have pre-assigned and fixed directionality. However, technology is evolving to enable new OXC architectures in which the directionality of regenerators and transceivers can be dynamically assigned on demand for each connection that requires regenerator(s). We have performed a detailed simulation study using a realistic network topology consisting of 53 nodes. The results show the benefits of the OXC architecture with dynamically assignable regenerator directionality in terms of (I) significantly lower connection blocking and (2) cost savings due to use of much fewer regenerators.
