Big data will usher in a new era in the field of optical communication opportunities
12/2/2013 , optical Online News : 2013 Optical Fiber Communication Development Report will be on November 28-30 and held a grand success in Guangzhou Panyu Chateau Star River Hotel , the General Assembly , " China's strategic broadband optical networking opportunities " as its theme , the experts participating bright communication practitioners, academics , entrepreneurs , engineers , totaling more than 200 people, as a co- fiber one online media , invited to attend the meeting.
Academician Wu He Quan : big data , when will usher in new opportunities for the development of optical communication
Chinese Academy of Engineering, Academician Wu Hequan report on the theme of "change trend of network layout ," Wu Academy report mentioned in the era of big data at least level is flat in the capital , between the same operator inside the provincial nodes using fiber optic cable directly connected to the transmission consideration of the system to reduce the number of router hops ; internet from birth to flatten the deployment , when the Internet more and more large, can not be done at all have a direct route between the router, the router will cause the whole flat jump a sharp increase in the number of currently several major telecom operators are deploying in this direction , which will bring new growth point.
Academician Wu also proposed along with the rise of Internet video , when the exchange of information between servers far more than the exchange of information between client and server , C2S way of facing great challenges in the future in a cloud computing environment , will become C2C mode, the cloud of servers . CDN plus further increase the flow of traffic on the Internet will have a significant impact , will lead to the center of the global Internet .
Big Data era revolutionize the network system , but also to further develop fiber optic transmission network market , for future optical communication development has brought new opportunities , such as with the expansion drive capacity , the need to build wavelength 100G system requires new cloud computing center construction of a new fiber-optic cables ; city metropolitan expansion , FTTH will further accelerate deployment , Ffmtocell and WiFi widely used within the cell increases the demand for optical transmission systems , centralized and distributed radio access network is encrypted cellular antenna layout within the cell optical networks.

Zhao Zi Sen academician : China fiber optic technology is not backward
" Father of Fiber Optics " Zhao Zi Sen academician mentioned that the new communication technologies Nianguang 2013 progress report , Zhaoyuan Shi summed up in the device class, in 2013 there are new technological breakthrough product : the range of 40nm wavelength tunable DBR lasers, through changes in voltage and temperature can change the wavelength of light ; vertical-cavity lasers VCSEL, is now priced at $ 1, VCSEL-DBR -type optical coupling efficiency of 80 % -100 % , the transmission distance of 5 meters ; integrated 100G optical transceivers ; 100G-DSP; the porous hollow fiber spiral can be used as working temperature 1000 degrees temperature sensor ; 16 * 16 light switches , there are SOA, the work rate of 10Gbps like product made in the year since the great degree of progress and breakthroughs .
Zhaoyuan Shi report also describes the current situation of China Fiber Optic
Communications : FTTH : the Ministry of Industry , " Broadband China 2013 " , 40 billion yuan investment in the development of fiber to the home FTTH, aims household bandwidths 4M, in Shanghai has reached 10M, FTTH Shanghai optical network covering 6.28 million ; fiber production : China's current production capacity of 140 million fiber km / year to supply fiber 12600km / year production capacity of 15,900 cable core km, ranking first in the world , optical fiber preform domestic 45.4% , imports by 54.6% , optical devices accounted for about 5% -6 % of the international market in the world rankings for the 5-6 , so China 's optical fiber communication technology is not backward, behind the U.S. and Japan.
