Tb/s OTDM technology

With the vast growth of traffic on the Internet from simple text data to high quality voice, images, and real-time video, it has become increasingly important to realize a high-speed network to support the daily needs of modern communications. We have recently succeeded in transmitting a 1.28 Tbit/s OTDM signal over a 70 km fibre with the adoption of third- and fourth-order simultaneous dispersion compensation. Key technologies for ultrahigh-speed OTDM transmission which exceeds 1 Tbit/s are described.
