A Novel Approach to Development of an Ultra High-Speed Optical Signal Processing Technology in Optical Communication Systems

Each time we take a count the number of subscribers for high-speed internet services increases, with the number of ADSL (Asynchronous Digital Subscriber Line). In an attempt to respond to such demand for large capacity optical communications technologies are currently being developed to increase the transmission speeds of optical signals and provide a highly dense multiplexing of wavelengths (DWDM: Dense Wavelength Division Multiplexing), as well as to expand the bandwidth for optical amplifiers.Out of all these technologies this paper concentrates on the ultra high-speed optical communication technology for increasing high-capacity communications and an overview of the 160Gbit/s optical transmitter receiver. This will be followed by a description of the orientation of recent research and development being conducted on a global scale with an introduction to the activities relating to the ultra high-speed optical signal processing technology.
