Dense Wavelength Division Multiplexing (DWDM) and the Dickson Grating

چکیده
Dec 2000 News: * Claiming a world-best speed record for optical data transmission, researchers at Siemens have transmitted 7 Tbits/s over a single optical fiber using DWDM. That's the equivalent of over 100 million telephone calls or a billion pages of typed data per second. The demonstration was conducted by Siemens' Information and Communication Networks Group at the company's Advanced Optical Networks Laboratories. The researchers simultaneously transmitted 176 channels of 40-Gbit/s data over a 50-km fiber optic cable. The 40-Gbit/s channels, in turn, were produced by time-division multiplexing (TDM) using a prototype of TransXpress FOX, a multiplexer and regenerator system developed by Siemens. 2. Basic DWDM

Introduction Recent progress in transmission capacity of dense wavelength-division multiplexed (DWDM) signals in a trunk optical fiber line now allows transmission of data beyond 10 Tbit/s over more than 100 km [1], [2]. The DWDM technology has to be applied to future millimeter-wave fiber-radio systems in order to take the capability to deal with the large amount of data capacity. There have b...
