ENTER INTO A STRATEGIC COOPERATION
Yangtze Optical Fibre and Cable Joint Stock Limited Company and Guoke Hanhai Forge In‑depth Strategic Cooperation

Jointly Build a New Ecosystem for Smart Perception

On August 7, 2026, Yangtze Optical Fibre and Cable Joint Stock Limited Company (hereinafter referred to as “YOFC Group”) and Guoke Hanhai Laser Technology (Beijing) Co., Ltd. (hereinafter referred to as “Guoke Hanhai”) formally signed a group‑level strategic cooperation agreement. Leveraging core industrial‑chain resources of both parties, the two sides will break through technical barriers between optical‑fiber sensing and laser‑based gas detection. Focusing on key areas including urban public safety, smart energy, industrial internet, 6G integrated sensing‑communication, work‑site safety production, and high‑trust industrial data infrastructure, they will develop full‑scenario intelligent safety monitoring systems to support the digital‑intelligent safety transformation of multiple domestic industries.

For this cooperation, the two parties have established a well‑defined collaborative operation system and adopted a three‑tier linkage implementation mechanism of “Group‑Business‑Project”, forming a four‑tier progressive cooperation framework covering “Strategy‑Project‑Technology‑Capital”.

Driven by four core pillars: group‑level strategic mutual trust, complementary business resources, rapid project delivery, and long‑term capital‑based alignment, both parties will jointly develop an integrated solution featuring “optical‑fiber sensing + laser gas detection + data fusion + AI early‑warning”. It covers five core business tracks: urban lifeline projects, smart‑energy safety, industrial work‑site safety production, smart optical perception, as well as 6G integrated sensing‑communication and industrial internet. A commercially viable business model will be built, featuring standardized replication, engineering‑oriented delivery, sustainable operation, and adaptability for both domestic and overseas markets.

Complementary Advantages of Both Sides

Deliver Integrated Perception Solutions
JOINT SOLUTION SYSTEM

As a global leader in the optical‑fiber and cable industry, YOFC Group owns a complete industrial‑chain layout for optical‑communication and distributed optical‑fiber sensing. Its businesses cover key sectors such as power, oil‑gas, marine industries and new energy. Since 2016, its core products have maintained the top global market share for ten consecutive years. Its global marketing network reaches more than 100 countries with strong marketing and channel expansion capabilities.

Guoke Hanhai focuses on the core track of TDLAS laser gas detection. It has developed more than 50 models across 8 product series, capable of precisely identifying over 18 types of industrial gases. A large number of benchmark projects have been delivered in gas‑pipe networks, petrochemicals, coal‑chemical industries, coal mines, emergency safety, new energy and other fields, with proven technical strength and practical project experience in high‑precision industrial‑gas monitoring.

The in‑depth integration of optical‑fiber sensing and laser gas detection technologies makes up for shortcomings of individual monitoring approaches. A complete full‑chain safety‑monitoring system is established, covering front‑end data acquisition, edge real‑time computing and intelligent AI risk early‑warning, effectively reducing false‑alarm rates and improving the accuracy of full‑domain risk management and control.

Deployment in Six Key Scenarios

Meeting Full‑industry Safety Requirements
DAS+TDLAS INTEGRATED PRODUCTS

Benefiting from integrated technical strengths, both parties will concentrate on delivering benchmark demonstration projects in six key application scenarios:

✅ Full‑domain monitoring for urban lifeline pipe networks, developing nationally replicable benchmark projects

✅ On‑line safety monitoring for special‑gas facilities and power transformers in factories

✅ Comprehensive early‑warning solutions for offshore oil‑gas drilling rigs and wind‑turbine nacelles

✅ High‑precision leak detection across the whole hydrogen‑energy industrial chain

✅ Multi‑source sensing‑data fusion to optimize AI early‑warning and mitigate false alarms

Priority will be given to demonstration projects. After standardized product solutions are polished, large‑scale promotion will be carried out across domestic sub‑sectors.

Multi‑level Coordination Mechanism

Long‑term In‑depth Strategic Alignment
INNOVATION OF SMART OPTICAL SENSING

To guarantee stable and long‑term cooperation, multi‑level supporting mechanisms have been put in place:

First, a three‑tier advancement model is implemented. A high‑level group strategic committee defines overall directions; regular work meetings synchronize project progress; business departments maintain routine communication; and special project teams take full charge of on‑site implementation.

Second, a two‑way priority cooperation mechanism is adopted. Both parties will give priority to adopting each other’s products and equipment for internal projects, jointly bid for tenders and explore domestic and overseas market channels together.

Third, a five‑year initial cooperation roadmap is formulated. Joint R&D, co‑development of industrial safety standards, and research on industrial‑fund docking will be advanced simultaneously. In the long run, deeper capital‑driven cooperation modes such as joint‑laboratory development and joint‑venture platforms will be explored.

Jointly Consolidate Industrial Safety Barriers

Support Process Control for Production

Nowadays, growing demands exist for full‑domain safety monitoring and intelligent production‑process control across scenarios ranging from urban underground gas‑supply pipe networks to petrochemical, coal‑chemical, coal‑mine, oil‑gas‑field, power, new‑energy and green‑fuel industries. This strategic alliance between YOFC Group and Guoke Hanhai breaks down technical boundaries between optical perception and precision gas detection. Based on highly‑reliable, high‑precision full‑domain monitoring products, it consolidates safety barriers for urban‑lifeline infrastructure, new‑energy industries and various industrial‑production scenarios. It empowers lean‑oriented process control for enterprises and raises work‑site safety standards across the whole industrial chain. Going forward, both sides will further explore the domestic smart‑safety market and jointly expand overseas industrial‑digitalization sectors. By technical integration and innovation, they will safeguard the bottom line of industrial development safety.
