R&D Technology, Application Scenarios, Production Capabilities, Sales Volume and Inventory of ODF Products by Hangzhou Jinlong Optic-electric Co., Ltd.

As a specialized, refined, distinctive and high-tech enterprise in the optical communication field, Hangzhou Jinlong Optoelectronics extends its core optical cable technologies to ODF (Optical Distribution Frame) related businesses. The following is a detailed description from five dimensions: R&D technology, application scenarios, production capabilities, sales volume and inventory:

1. R&D Technology

The company’s R&D strength is supported by both a professional team and patented technologies. It has long engaged optical communication experts enjoying special government allowances from the State Council to provide technical support, and owns 29 patents and 1 software copyright. Technically, it can leverage the pressure-resistant and protective technologies in the optical cable field to enhance ODF adaptability. For example, the independently developed C-shaped skeleton optical cable structure allows internal fibers to move within limits, forming a buffer when subjected to external forces. This design concept can be migrated to the internal fusion splicing tray and optical cable interface structure of ODF, reducing stress damage to fibers inside the distribution frame. Meanwhile, the ODF is compatible with various mainstream fiber types, including G652D, G657A1 and other conventional single-mode fibers as well as special fibers produced by the company itself, ensuring low-loss transmission when the ODF is used with fibers. Each fiber core’s loss is tested and recorded before delivery to improve link stability.

2. Application Scenarios

The core application scenarios meet the optical fiber cabling needs of communication operators, government departments and enterprises. In the core computer rooms and regional computer rooms of China Mobile, China Unicom and China Telecom (the three major telecom operators), it is used for the convergence management of long-distance and local network optical cables, adapting to the large-scale fiber scheduling needs of operators. It is also suitable for the weak current rooms of data centers and enterprise parks, providing organized management of fiber lines for servers, switches and other equipment to ensure the stable transmission of voice, data and other services. In addition, relying on the Qualification Certificate for Accessing Equipment and Materials of National Defense Communication Networks, its ODF can be supporting used for fiber distribution in computer rooms related to national defense communication. At the same time, it can meet the needs of optical cable termination splicing and optical path adjustment in cable TV networks, aligning with the supporting scenarios of its own cable TV cable business.

3. Production Capabilities

The company has complete production hardware and qualification guarantees, including 8 optical fiber drawing production lines, 12 SZ stranding equipment and many other professional devices, with an annual production capacity of 10 million fiber cores of optical cables, which can provide sufficient supporting optical cable resources for ODF production. It has obtained multiple certifications such as ISO9001, ISO14001 and TL9000, and the ODF-related production processes can reuse the strict quality control standards of existing optical communication products. In addition, its products have passed the access certification of the State Administration of Press, Publication, Radio, Film and Television, with a mature production system that can realize the coordinated large-scale production of ODF and optical cables, meeting the integrated supply needs from fibers to distribution frames in different scenarios. The products also comply with international standards, laying a foundation for export.

4. Sales Volume

The sales channels cover the domestic government-enterprise market and overseas markets. Domestically, it has long-term cooperation with the three major operators such as China Mobile and China Unicom, and has repeatedly won bids for optical cable procurement projects of enterprises including Cixi Digital TV and Zhejiang Xiangrong Digital Technology. ODF can be supplied to these cooperative customers as supporting products. Overseas, its optical cable products have been exported to many countries, and ODF can enter overseas communication markets such as Singapore and Russia along with optical cable products by virtue of supporting advantages. Although there is no separate public data on ODF sales volume, relying on the annual production capacity of 10 million fiber-kilometers of optical fibers and 10 million fiber cores of optical cables, its ODF sales volume can match the bulk procurement needs of downstream customers. The company further expands its sales share by participating in various international communication exhibitions.

5. Inventory

There is no separate public data on ODF inventory, but it is speculated that the company adopts a flexible inventory strategy aligned with market demand. On one hand, for long-term and stable customers such as the three major domestic operators, it reserves inventory of ODF with corresponding conventional specifications to ensure rapid order delivery. On the other hand, for overseas and customized needs, it coordinates the procurement and inventory rhythm through its affiliated import and export company. At the same time, the company improves the industrial chain layout by holding shares in subsidiaries, and can adjust inventory through upstream and downstream coordination to reduce inventory backlogs caused by lack of accessories. It also dynamically adjusts inventory according to the winning status of bidding projects to adapt to phased procurement peaks.

With its flexible branch structure, low-loss optical performance, reliable environmental adaptability and strict standard certification, BOC optical cable has become an indispensable part of modern communication networks. From FTTH to data centers, from base station connections to large-scale events, BOC optical cables, with their excellent parameter characteristics, provide a solid support for efficient and stable optical communication. With the development of 5G, 8K and other technologies, BOC optical cables will play a key role in more high-bandwidth and high-density scenarios.

Colored optical fibers are placed into a loose tube made of high-modulus material, which is filled with thixotropic water-blocking gel. The core of the cable consists of a metal strength member. The loose tube(and filling rope)is twisted around the central strength member to form a circular cable core. Gaps within the cable core and between the cable core and the steel tape are filled with water-blocking gel. After longitudinal wrapping with coated aluminum tape and extrusion of a polyethylene inner sheath, the cable is wrapped with coated steel tape and extruded with a flame-retardant outer sheath

ET optical cables typically enclose 250μm single-mode or multi-mode fibers in loose tubes made of high-modulus materials. This loose tube material has good hydrolysis resistance and high strength, which can provide reliable mechanical protection for the fibers and help reduce the impact of the external environment on the fibers. The loose tube is filled with non-toxic and harmless waterproof compounds, such as special ointments. This not only prevents moisture from entering the fibers but also buffers external pressure to a certain extent, providing key protection for the fibers.
