Abstract : The first part of the report discusses both theoretical and experimental achievements in proposed unidirectional and bi-directional self healing inter-office WDM ring networks. Two different WDM schemes of self healing ring architectures were considered: 2-fiber unidirectional rings and 4-fiber bi-directional rings. Both types of ring networks are themselves completely survivable. The second part deals with the development of critical components required for the implementation of proposed OTDM network architecture. Specifically it examines switching characteristics of SOAs when used for external modulation and demultiplexing at both transmitter and receiver ends of a multi-Gb/s OTDM system. The third part of the report describes the overall progress achieved regarding the use of SOAs as extemal analog modulators to replace the use of semiconductor laser diodes otherwise required for direct modulation at the transmitter end of AM-VSB SCM CATV systems.
