The reporter learned from the Wuhan Research Institute of Posts and Telecommunications on the 4th that the 973 project led by the institute "ultra-high-speed ultra-large capacity ultra-long-distance optical transmission basic research" has made a new breakthrough, which can transmit larger capacity under the same bandwidth, and realize a pair of optical fibers simultaneously transmitting the call of 114 million people up to 3600 kilometers
.
Previous related reports:
Alcatel-Lucent announced that scientists at Bell Labs have recently increased the speed of optical transmission to more than 100 Pb/s (1Pb=1000Tb) for the first time, transmitting the equivalent of about 400 DVD movies per second over a distance of more than 7,000 kilometers, which is equivalent to crossing the Atlantic from Paris, France to Chicago
, USA.
This is the highest speed ever recorded for transoceanic optical transmission, up to
ten times faster than today's most advanced commercial submarine cables.
In order to achieve such speeds, researchers at Bell Labs in Villarceaux, France, have adopted a series of new technologies in modulation, transmission, signal processing, etc.
, such as the use of 155 lasers with different frequencies, each of which can carry 100Gb/s data, and the performance is greatly enhanced
compared with standard wavelength division multiplexing (WDM) technology.
In addition, the distance between the repeaters of the test network reached 90 kilometers, which is 1.
2 times that of
similar ordinary networks.
High-speed optical transport is also a key part of Alang's High Performance Network (HLN) architecture, which has been adopted
by several operators.
