1.7 terabits per second (85 x 20 gigabits per second) over 9,180km on a single fiber - comparable to transpacific distances.
Mitsubishi Electric continues its uninterrupted development of transoceanic technology.
Using a range of recently-developed optical transmission technologies, Mitsubishi Electric has successfully demonstrated an outstanding 1.7 terabits per second wavelength division multiplexed transmission over 9,180km at 20 gigabits per second per wave.
These developments open new possibilities for next-generation submarine cable systems and long-distance terrestrial networks for the international network connecting Japan, the United States, Asia, Europe, etc., and the trunk infrastructure connecting the major cities of Japan and other countries.
Mitsubishi Electric Corporation is a highly-diverse manufacturer operating in most major branches of electrical and electronic technology. It is among the top rank of suppliers of wet and dry plant to the optical submarine cable industry.
As the expansion of the Internet progresses, the capacity demanded of trunk lines increases. Mitsubishi Electric has developed a channel bit-rate of 20 gigabits per second as the optimum for the present in terms of its potential for reduced cost, ease of operation, and transmission reliability compared with either 10 gigabits per second or 40 gigabits per second.
To transmit 20 gigabits per second WDM signals over transoceanic distances in the face of fiber nonlinearity effects, Mitsubishi Electric has developed novel technologies to improve the optical signal-to-noise ratio and to compensate for the signal distortion produced by the fiber nonlinearities.
In order to transmit 40 gigabits per second transparently across the new system, Mitsubishi Electric is developing in conjunction with it a 40 gigabits per second client interface using a novel inverse multiplexing technique.
