The world's first integrated 10G PON test bureau released China Unicom to lead the development of new optical access technologies

Communication International Network News (CWW) On September 7, 2016, my country Unicom Ultra-Broadband Access and Utilization Industry Alliance Summit Forum was held in Shenzhen. Mao Qian, leader of the network expert consultation group and my country Communication Standardization Association Transmission and Access Technology Task Committee, participated in the speech. The meeting was hosted by Dr. Tang Xiongyan, chief expert of my country Unicom Network Technology Research Institute.

At the meeting, Mao Qian, head of the transmission and access network expert consultation group of the Communication Science and Technology Commission of the Ministry of Industry and Information Technology, Dr. Tang Xiongyan, chief expert of my country Unicom Network Technology Research Institute, my country Unicom announced that it has completed the world's first integrated 10G PON test bureau in Qingdao in conjunction with ZTE. Subsequently, Wang Guangquan, Director of the Network Technology Research Department of my country Unicom Network Technology Research Institute, introduced the research on my country Unicom's next-generation ultra-broadband access technology with the title of "Uniform Ultra-Broadband Access - G.Metro Specifications, Technology and Application".

China Unicom and ZTE Release the World's First Converged 10G PON Test Bureau At the meeting, my country Unicom announced that it has completed the world's first converged 10G PON test bureau in Qingdao in conjunction with ZTE. Originally, my country Unicom's research on 10G PON has already been opened. In 2014, my country Unicom arranged three 10G PON research test tasks in the laboratory environment, and arranged 10G PON (FTTH+FTTB) field pilot verifications of new technologies in Guangdong, Shanxi, Liaoning and Tianjin.

China Unicom Convergence 10G PON Test Bureau released

From the perspective of equipment centralized procurement, China Unicom launched 10G PON centralized procurement in May 2016, during which 10G GPON was the first large-scale centralized procurement in the world, which opened up a precedent for the commercial use of 10G GPON technology plans. With the completion of my country Unicom's 10G PON centralized procurement task, my country Unicom's current network is now planning to deploy 10G PON.

Bei Jinsong, general manager of ZTE's fixed-line optical access products, pointed out that because there are a small number of GPON equipment products in the existing network, if 10G PON is to be deployed in the existing network, it will not only increase the cost of transformation, but also greatly increase the operation and maintenance. capital. As we all know, the price and pictures of IWC watches on traditional GPON/10G GPON networkThe upgrade and transformation plan uses internal WDM multiplexing equipment to combine the optical signals of GPON and 10G GPON into the same ODN method, which undoubtedly increases the complexity of operators' network establishment and operation and maintenance management. In this situation, the converged 10G PON came into being.

Dr. Tang Xiongyan, chief expert of China Unicom Network Technology Research Institute, Dr. Tang Xiongyan, general manager of ZTE's fixed network commodity line optical access products

, said that the integrated 10G PON plan can be implemented without changing the existing OLT, ODN, and adding racks, etc. Upgrade to 10G PON, effectively reducing the cost of network transformation and upgrading, and also greatly prolonging the establishment period.

The blended 10G PON test bureau is completed by mixing GPON/blended 10G PON boards on the ZTE ZXA10 C300 OLT. One blended 10G PON board is equivalent to two single boards of GPON and 10G GPON, and there is no need to add new equipment room racks. space, without increasing user capacity, and achieving intensive and smooth upgrades at the maximum level, providing an innovative plan for the evolution of GPON to 10G PON.

After the launch ceremony of G.metro technology between China Unicom and the industry

, Director Wang Guangquan of the Network Technology Research Department of China Unicom Network Technology Research Institute announced a keynote speech, discussing China Unicom's imagination and plans for the next-generation access technology-G.metro technology .

Wang Guangquan, Director of the Network Technology Research Department of my country Unicom Network Technology Research Institute, G.metro technology is aimed at low-cost multi-service integrated access in the metro area. The application scenarios include mobile fronthaul, mobile backhaul, company dedicated line, high-end fixed broadband access, etc., which can be directly supplied Optical wavelength to RRU/base station/desktop/user, etc., to achieve wavelength-level high-bandwidth services, has been widely valued by the industry.

Since my country Unicom took the lead in the formulation of the G.metro specification in April 2014, the Network Research Institute has been actively developing the review and formulation of the G.metro specification and the development of corresponding equipment in conjunction with international and domestic industry mainstream equipment suppliers and chip optical module suppliers. At the end of this month, my country Unicom Network Research Institute and Germany's ADVA Company launched the test and verification of G.metro equipment for mobile prequel applications in the main language city laboratory and Tianjin Unicom's current network.

Director Wang Guangquan said that he hoped to invite more optical communication manufacturers from overseas and overseas to participate in the seminar system of Unicom G.Metro through this meeting of China Unicom's Ultra-Broadband Access Industry Alliance, so as to jointly promote the development of my country Unicom's next-generation optical access technology and evolution. In order to promote the development of next-generation optical access technology, my country Unicom led the establishment of the Ultra-Broadband Access Industry Alliance as early as September 2015. Up to now, more than 20 equipment, module and chip manufacturers have participated in the Ultra-Broadband Access Industry. Alliance, the establishment of which has effectively advanced the development of the optical access industry
