HOC SWA Armored Subsea Fiber Optic Cable: Reliable Underwater Connectivity
HOC SWA armored subsea fiber optic cable is a robust and reliable solution for underwater communication needs. Designed with a uni-tube structure and steel wire armoring (SWA), this cable is built to withstand the harsh conditions of subsea environments. Its enhanced durability and high performance make it ideal for various underwater applications.
Description
Subsea fiber optic cables face significantly more demanding laying conditions compared to direct buried cables. The challenges of underwater installation and repair necessitate higher reliability standards. HOC SWA cable addresses these challenges with its steel wire armor, providing essential protection. The cable’s sheath is carefully chosen based on the specific hydrogeological conditions of the deployment environment.
Application
HOC SWA cable is suitable for:
- Underwater deployments
- Climbing installations
- Direct burial applications
Features
- Central tube design accommodating 8 to 24 fibers.
- Steel wire armoring (SWA) for enhanced tensile and impact resistance.
- Double sheathing for superior moisture resistance.
- Sheath materials: PE and LSZH options available for different requirements.
- Excellent hydrolysis resistance and high strength.
- Water-blocking tape and materials for added protection.
- Good mechanical properties and temperature characteristics.
- Loose tube filled with special tube filling compound for critical fiber protection.
