OFweek Optical Communications Network News At present, our country has deployed the world's largest 100G network. As users' demand for traffic and broadband surges, 400G has been put on the agenda.
In preparation for 400G, the industry has begun to pay attention to new optical fiber and cable technology.
Recently, Dr. Song Haiyan, general manager of Xigu Optong, accepted an interview with reporters and shared Xigu Optong’s experience in the production and testing process of new G.654 optical fiber cables.
The first company to complete the new type of G.654E optical fiber cable
In 2015, in order to study the application of new G.654 optical fiber in terrestrial 400G and above high-speed systems, China Unicom launched a test project in Xinjiang - "Hami-Barkol Section".
"As a long-term partner of China Unicom, Xigu Optong has fully participated in this project and is mainly responsible for optical fiber incoming factory inspection, molding, cabling, sheath production and inspection.It proves whether the ordinary optical cable manufacturing process can be applied to the new G.654 optical fiber.
" Dr. Song pointed out.
To meet terrestrial applications, the new G.654 optical fiber should have low attenuation, large effective area, and low bending loss
This project uses 16 new G.654 optical fibers from 7 optical fiber manufacturers for testing. The purpose is to verify the use of new G.654 optical fibers from different manufacturers and different parameters on land. The performance in the environment provides a basis for the next step of formulating the new G.654 optical fiber standard.
In addition, Xigu’s own 48-core G.652D optical fiber is also used in the optical cable for simultaneous testing and comparison.
This year is the 30th anniversary of the establishment of Xigu Guangtong. Xigu Guangtong has grown together with my country's optical communication construction. Xigu Guangtong has successfully completed the project with its 30 years of accumulated production experience. The acceptance work of this China Unicom trunk line project has been completed, and all performance indicators are better than industry standards
Dr. Song said: "Xigu Guangtong, as the first domestic The first manufacturer to complete the cabling of the new G654 optical fiber means that Xigu Guangtong has the cabling technology of the new G654 optical fiber and can provide technical support for China Unicom to promote the new G654 optical fiber and cable in the future.
" With the completion of the laying of the "Hami-Barkol" trunk optical cable, China Unicom will further verify the performance indicators of the new G.654 optical fiber, and also provide the basis for the next step of land-based G..654 optical fiber industry standard preparation to lay the foundation.
Fiber optics need to be closely coordinated with the development of optical systems
With the emergence of 4K video, VR and other applications, user needs are becoming more and more demanding Diversified, the requirements for optical fiber systems are getting higher and higher. In the vision of "all types of interconnection", connection is the foundation, which also puts forward new requirements for optical fibers.
At present, 400G is about to usher in large-scale deployment. In the 400G era, dispersion is no longer the most concerned parameter of optical fiber, but has higher requirements on attenuation and nonlinearity, ultra-low loss, large effective area optical fiber and other new optical cables. Become a hot research topic in the industry.
my country's fiber optic cable production capacity and demand have accounted for more than half of the world's share, but it still lags behind developed countries in terms of new optical fibers such as ultra-low loss and large effective area.
Dr. Song believes: "Our country's original inventions in basic research, materials, etc. lag far behind developed countries such as Europe, the United States, and Japan. The industry needs to carry forward the 'craftsman spirit' and conduct solid research to achieve the goal of transforming from a large fiber optic country to a powerful country."
”
Dr. Song pointed out that the promotion of new optical cables is a double-edged sword. The industry must accept new things in a reasonable manner, and also learn from the lessons learned from the large-scale installation of G.655 optical fibers in the past, taking into account costs, and Regarding the compatibility of existing network optical fibers and the development trend of optical transmission technology in the future, optical fiber manufacturers need to strengthen communication and cooperation with industry-leading optical transmission equipment manufacturers such as Huawei.
At present, our country is vigorously promoting "Made in China 2025" and "Industry 4.0", and the industry has focused on "intelligent manufacturing". In Dr. Song's view, the Internet, Internet of Things, cloud computing, etc. are gradually being introduced into the manufacturing industry. The trend is unstoppable
In order to improve production efficiency, Xigu Guangtong added. Strengthen site-based lean production management and strengthen concepts such as 5S, TPM, and quality management.
In terms of workshop management, the latest concepts such as "Made in China 2025" and "Industry 4.0" have been introduced. Automation, intelligence, and lean technologies improve efficiency and reduce costs.
At present, optical fiber and cable manufacturers regard overseas expansion as an important way to grow their performance. As a joint venture, Xigu Guangtong has a foreign investment background and has its own views on the "going global" of optical fiber and cable manufacturers.
Dr. Song pointed out that when my country's optical fiber and cable companies expand overseas markets, they must pay attention to localization and continue to cultivate outstanding talents in overseas market development, operation and management.
