Recently, the FiberHome technology in China for the first time to achieve 560Tb / s WDM and space division multiplexing optical transmission system experiment, the transmission capacity is the daily standard single-mode optical fiber transmission system, the largest The capacity of five times, you can achieve a fiber of 6.75 billion pairs of people (135 million people) at the same time call, marking China’s ‘ultra-large capacity, ultra-long distance, ultra-high rate’ optical communication systems research into a new level .
According to Xinhua reports, this experiment uses a single Fiber Channel technology with independent intellectual property rights for the seven-core optical fiber transmission medium and ordinary fiber is different from a single-mode seven core fiber equivalent to seven ordinary fiber combined into one. If the optical fiber information transmission analogy to the highway, ordinary fiber if it is a single lane, then the single-mode seven-core optical fiber is equivalent to seven parallel lanes, can provide 7 times the transmission capacity of ordinary fiber.Through the technological and technological breakthroughs, the flames Independent intellectual property rights of single-mode seven-core fiber to solve the multi-core crosstalk between fiber problems, isolation -70dB, the ‘lane’ and ‘lane’ between the interference and impact to a minimum.
In the transmission media innovation, the system used in this experiment equipment for the ‘large capacity, large speed, ultra-long distance’ optical transmission provides a strong support system equipment is equivalent to the entire optical transmission system hub, the system equipment Using 16 single light sources, through the optical multi-carrier generator, through the optical multi-carrier generator to produce a total of 375 photonic carriers to form 375 25GHz optical transmission channel spacing, single-core transmission capacity of 80Tbit / s, the system transmission capacity To 560Tbit / s, the group test and verify, the realization of the ‘560Tbit / s ultra-large capacity single-mode multi-core optical fiber transmission system’ for the first time, reached the international advanced level.
With the rapid development of mobile Internet, cloud computing, large data and Internet of things, the traffic surges have brought great challenges to the information communication network. The ‘spurt-growth’ problem solving the network data flow is becoming the competitive heights in the global information and communication field. Fiberhome is committed to continuous innovation to reshape the future of communications networks, and constantly for the future development of large-capacity optical transmission solutions.
In 2014, the first time to achieve a common standard single-mode optical fiber C + L-band 100.3Tb / s optical fiber transmission technology, in the field of ‘large capacity, ultra-high-speed, ultra-long distance’ optical communication transmission field, the success of the birth of major scientific and technological achievements, S capacity transmission experiment, and the Chinese lunar exploration phase three reentry flight test with the two selected by the academicians of the ‘Top Ten Science and Technology Progress News.’ In 2015, the transmission capacity of 200Tb / s the same year, ‘three super’ Technology commercial practice to achieve a major breakthrough in the completion of the 2.5Gb / s 468km long span coherent optical transmission system Fuzhou power grid demonstration project.This project is currently the first self-study digital coherent long-span optical transmission system project, the scale of commercial Expected in 2017 in full swing.
With the gradual trial commercialization and network cloud of 5G, China’s research on ‘ultra-large capacity, ultra-long distance and ultra-high rate’ has provided key technologies for future information technology application and industrial development, and boosted China’s future information Technology in the international forefront.
Adhere to the broadband network of China’s main battlefield, strong guidance, strong market; adhere to the national network of information security needs of the heavy, heavy-duty, high-tech, high-tech, Re-layout, optical communications in the field of technological innovation to achieve a global leader in the industrialization of information technology services through the cohesion for the supply side reform provides a strong support.
In the future, Fiberhome will continue to accelerate the construction of the knowledge innovation platform with the State Key Laboratory as the core, the construction of technological innovation platform centered on the enterprise technology research and development center and the support service platform with the double incubator as the core, Key core, high-end optoelectronic devices and chip research and development breakthroughs, and strive to build the world’s optoelectronics industry, science and technology innovation Heights.
