From century-old copper telegraph cables to high-capacity fiber-optic submarine cables, undersea fiber networks carry over 99% of all intercontinental data traffic worldwide. The rapid development of offshore wind power and island interconnection projects raises stringent protection requirements for cables operating in shallow waters within 200 meters, where reefs and fishing activities pose frequent hazards. CCOFC specializes in manufacturing submarine cables rated for depths up to 200 meters. Featuring multi-layer armored water-blocking construction, our cables offer superior wear, pressure and corrosion resistance with full custom specifications to serve all shallow-water marine communication projects. We welcome inquiries for project cooperation.

As CCOFC Changcheng Optical Cable Manufacturer, we keep tracking cutting-edge optical cable technologies for AI computing networks.
