Optical networking technology has progressed significantly over the last few years. The transmission bit rate has matured at 40 Gbps, 80 Gbps and reaching even 160 Gbps over ultra-long terrestrial and intercontinental networks. Simultaneously several optical channels carrying these transmission signals are multiplexed over the entire S-, C- and L-bands of the minimum attenuation window of silica fibres leading to total information capacity to tens of Tera-bps. This presentation gives an overview of and recent advances on the optical transmission and wavelength multiplexing technology and channel routing techniques for Tera-bps optical networking. The impacts of such transmission technology on optical networks would be investigated.

The following issues would be summarized and described for such networks:
1) Optical modulation techniques, especially the return-to-zero transmission format and its impact on the design and implementation of optical transmitters
2) Fibre dispersion issues and its management techniques
3) Polarization mode dispersion and compensation techniques
4) Optical amplifiers including EDFA and Raman amplifiers and gain equalization
5) Optical receivers and de-multiplexing technology
6) Optical routing and networking technologies
Issues involving the implementation of such optical network technology would also be discussed.
