Early days of optical fiber
Tatsuo Izawa, NTT Electronics
Senior Advisor to the board of NTT Electronics Corp
In the 1970s, various issues of fibre technology including fabrication processes, materials, device structure etc were discussed and studied in order to realize optical fibre communication systems. In the process of the development, there were many hidden stories of failure. A hidden story of fibre in early days will be given in this talk.

New frontiers in optical communication
Masataka Nakazawa
Professor, Tohoku University
In this talk, two emerging transmission technologies are described. One is ultrahigh-speed OTDM transmission, in which I describe 160 Gbit/s over 1,000 km distortion-free transmission using a time-domain optical Fourier transformation. The other is coherent optical transmission, in which I describe a 1 Gsymbol/s coherent 64 QAM transmission with a spectral efficiency of 8 bit/s/Hz.

Internet social networking drives network capacity growth
Stan Lumish, JDSU
CTO
Social networking, such as YouTube, MySpace, Facebook and others, are not only changing the way people interact. Content-rich applications such as music- and video-downloads, and on-line gaming, may be the killer applications for driving network bandwidth growth. In response to these demands, network providers must implement new optical core networks, now manage at the wavelength level and augment bandwidth through optical access network solutions. These new network solutions bring with them new challenges, especially in the area of photonic devices, wavelength management and test and diagnostics. This presentation will discuss the solutions to these new challenges and their impact supporting these new trends.
