Recently, according to the requirements put forward by the overseas customer, Yangtze Optical Fibre and Cable Joint Stock Limited Company (stock code: 6869. HK, hereinafter referred to as "YOFC") has successfully developed the new cable product with the performance of "three proofings", namely, prevention of mice, ants and fire, which will be used for the construction of communication infrastructure projects of urban rail transit.

Structure Drawing for the New Cable with "Three Proofings"

The cable with "three proofings" researched and developed by YOFC possesses excellent fireproof performance and satisfies the international standards of IEC60332-3-24 Bunched Cable Combustion Test, IEC60331-25 Link Integrity Test, IEC60754 Halogen Acid Gas and Acidity Test, IEC61034 Smoke Density. Even if there is a fire, the communication will be unblocked in a long time, so as to guarantee the operation of key equipment, start the alarm, reduce the fire hazard, and ensure the safety of life and property. Plenty of excellent performance that such new-type cable has can guarantee the application safety of the cable in the complicated environment.

With the rapid development of rail transit, cables have been widely recognized due to such characteristics as high security, electromagnetic compatibility, reliability, multi-interfaces and extensibility. However, the application environment of rail transit is complicated that many hidden dangers such as fires and biological attack exist resulting in the extremely easy destruction of the regular cable structure. Therefore, the cable products which have the excellent performance and can be used in the complicated application environment are widely used in the overseas rail transit market. The new cable with "three proofings" developed by YOFC has passed various mechanical performance and environmental performance tests, such as optical fibre attenuation, PMD, tension test, impact test, flattening test and alternating bending test, which can fully satisfy the clients' requirements.

As the industry leader in the optical fibre and cable market, with the idea of "independent innovation and external cooperation", YOFC always insists on the talents, mechanism and ideas as the significant elements of the company's innovative culture, constantly boosts the technical innovation of the optical fibre and cables, actively develops new markets, and keeps the core technology in the lead.
