Design and Control System for Regional CWDM Optical IP Networks with Reconfigurable Optical Add/Drop Multiplexers

DOI

Description

A Web-based design and control system has been investigated for regional optical IP (Internet protocol) networks. The system can design lightpaths connecting nodes such that given traffic is groomed with minimum number of wavelengths, or give a reserve design with additional lightpaths to groom future traffic. Reconfigurable optical add/drop multiplexers (R-OADMs) were also investigated and manufactured. An experimental network with the R-OADMs was constructed, and the control function of the implemented system was examined by reconfiguring the lightpaths in the experimental network. The R-OADMs could be controlled and the lightpaths could be reconfigured successfully by the system.
