“Open all year round during the Spring Festival”
At Nanjing Huaxin Tenzan Optical Communication Co., Ltd.
Red lanterns are hung high.
The production workshop is bustling with activity.
Full steam ahead to accelerate the progress and boost production
Go all out for a “first win”!
The top of the tower was being polished, and the huge preformed optical fiber rods were slowly descending.
At the core of the tower, a 200-millimeter-diameter and approximately 3-meter-long optical fiber preform rod is heated and softened by the high temperature of over 2000 degrees Celsius within the drawing furnace.
At the bottom of the tower, it’s like making “sugar filaments”. The softened preformed rods are “spun out” by the drawing machine, forming optical fibers with a diameter of only 125 micrometers and as thin as a hair.
This single “glass thread”
How capable can one be?
“Traditional communication optical fibers are like ordinary roads, with data moving along them like vehicles choosing their own routes – some take longer detours, some get stuck in traffic jams, the paths are random and the latency is unpredictable; a computing power network requires dedicated channels – they depart on time, do not stop midway, and have a fixed path, with high speed, low latency and stable transmission.” Xu Jingyi, the deputy general manager of Nanjing Huaxin Tengcang, introduced, “The massive data scheduling between computing power centers is extremely sensitive to the signal loss and transmission delay caused by squeezing and bending during the laying of optical fibers. And high-strength anti-micro-bend optical fibers are exactly the innovative answer that ‘The Seekers’ have delivered.”
This new type of optical fiber is equivalent to upgrading an ordinary road into a high-speed dedicated channel. Under conditions of pressure, vibration, and minor bends, the signal loss can be reduced by approximately 30%. Don’t underestimate this 30%. In a busy computing power network, this is one of the key factors for massive data not to be congested, not to queue up, and to transmit stably and at high speed.
As the AI wave sweeps across the globe, the demand for low latency and large bandwidth in computing networks has reached an unprecedented level, and the demand for high-performance optical fibers has also risen accordingly. A report by Huatai Securities on February 2nd stated that in January 2026, the price of G.652.D single-mode optical fiber in the Chinese market reached a new high in nearly seven years, with the average price exceeding 35 yuan per core-kilometer. The price increase in just January alone was over 75%.
The surge in market demand has directly translated to the production end. During this year’s Spring Festival, this fiber manufacturing enterprise, which has been rooted in Nanjing for 30 years, persisted in production, providing crucial “information nerves” for the construction of global computing networks.
“Our company currently has all 38 fiber optic production lines operating at full capacity, and they are always in a state of full production every month. However, there is still a shortage in delivery.” When I met with the company’s general manager Li Wei, he had just returned to Nanjing from a business trip in another place. During the entire Spring Festival holiday, he will spend it negotiating partnerships and inspecting production lines. According to him, from 2023 to 2024, the company has increased its production capacity by 8 million core kilometers on the basis of the original level; in 2025, it will produce approximately 34 million core kilometers of fiber optic; and in 2026, it will further accelerate and upgrade the production lines, with an expected shipment volume of 40 million core kilometers. “This year, the export volume is expected to double year-on-year, with a focus on covering regions such as North America and Europe,” he said.
Being busy is the norm during the Spring Festival for “Light Chaser”
Li Hongjun, an 80s-generation wire drawing process engineer from Anhui Province, came to Nanjing to reunite with his parents this Spring Festival. After having a reunion dinner with his family on New Year’s Eve, he returned to work on time on the first day of the new year. While precisely regulating the wire drawing process parameters, he also handled the backlog of special optical fiber orders from the previous period.
In the quality control department of the company, Zheng Qingkai is picking up a fiber optic and using scissors to cut off a small section and place it on the equipment. Having been engaged in fiber optic dispersion detection for over ten years, he is mainly responsible for conducting “examinations” on the fiber optic before it leaves the factory – by conducting random inspections to check whether the optical signal will “disintegrate and distort” during transmission. If the dispersion exceeds the standard, the originally complete optical signal will become disordered as if a well-organized team is running and then eventually fail to be accurately recognized by the receiving end. Only when the test is qualified can the fiber optic be sent to the front line of computing power construction.
As the noon approached, after completing the testing of this batch of samples, Zheng Qingkai and his colleagues headed to the cafeteria. Braised lion’s head, braised mutton, oyster sauce beef, steamed small yellow fish, parsley and spicy sauce… The hot dishes filled the dining table. Someone took a photo of this week’s menu and shared it with colleagues: “The variety is quite rich, and the dishes are not repeated every day.”
The orders have been queued up until the export volume doubles in the second half of the year. This Nanjing-based enterprise is running at full speed and accelerating with a “fully charged” state. It is striving to build the “1026” advanced manufacturing cluster system in Nanjing and create the “Nanjing Upgrade Edition” of the national artificial intelligence innovation application pilot zone. In this process, these thin fibers, as thin as strands of hair, are connecting the “golden channels” of the computing power era. They are not only connecting data centers and servers, but also the confidence and strength of this city to move towards the future.
