HOC Multi Loose Tube Steel Wire Armored (SWA) Underwater Fiber Cable
HOC offers a diverse range of underwater fiber cables, including this multi loose tube steel wire armored (SWA) variant. Designed for demanding subsea environments, this cable ensures reliable and long-lasting performance for critical underwater communication links.
Description
Submarine optical cables, also known as underwater fiber cables, operate under more stringent and demanding conditions than standard underwater cables. A critical requirement for these cables is a service life exceeding 25 years. To achieve this, robust construction, including steel wire armoring (SWA), is essential. The cable sheath is carefully selected to match the specific hydrogeological conditions of the deployment location.
Application
This cable is suitable for:
- Underwater deployments
- Climbing installations
- Direct burial applications
Features
- Steel wire armoring (SWA) for enhanced tensile and impact resistance.
- Double PE sheath for excellent moisture resistance.
- Steel wire central strength member for added durability.
- Good hydrolysis resistance and high strength.
- Water-blocking tape and materials for superior protection.
- Excellent mechanical properties and temperature characteristics.
- Loose tubes filled with a special compound to safeguard the optical fibers.
- Crush resistance and flexibility.
