LINDEN-SPE-7040-020 Buoyant Buoyant Singlemode 9/125 Fiber Optic Cable is a specialist underwater and marine fiber optic cable designed for applications where the cable needs to remain buoyant in water while providing reliable optical signal transmission. This cable is built with one singlemode optical fiber and an outside buoyant layer, making it suitable for floating, tethered, subsea, and water-deployed communication systems.

The cable uses 9/125 singlemode fiber, which is widely used for long-distance, high-speed optical communication. It supports low-loss signal transmission and is suitable for applications where stable data transfer is required over extended distances. With a single optical fiber inside the cable, this product is ideal for compact underwater communication links, sensor connections, monitoring equipment, and specialist marine systems where only one fiber channel is required.

A key feature of the LINDEN-SPE-7040-020 cable is its external buoyant layer. This outer buoyant construction helps the cable float or maintain controlled buoyancy in water, reducing the risk of sinking, dragging, snagging, or becoming trapped on underwater surfaces. This makes the cable useful for temporary deployments, marine testing, underwater vehicles, floating sensor systems, surface-to-subsea communication, and research operations.

The cable is designed to provide a balance of optical performance, buoyancy, flexibility, and mechanical protection. Its rugged construction helps protect the internal fiber from moisture, handling stress, bending, and underwater environmental exposure. The outside buoyant layer adds extra protection while supporting easier handling and recovery during deployment.

This buoyant singlemode fiber optic cable is suitable for marine, offshore, oceanographic, defense, industrial, and research environments where reliable optical communication is required in or around water.
