LINDEN-SPE-7059-4 High-Strength Buoyant 2000 is a rugged buoyant fiber optic cable designed for demanding underwater, subsea, marine, ROV, tether, defence, oceanographic, and harsh-environment communication applications. It is built for projects where the cable must remain lightweight in water while still providing strong tensile performance, reliable optical transmission, and excellent protection against abrasion and handling stress.

This cable belongs to Linden Photonics’ high-strength buoyant STFOC™ cable family. The public product selector for LINDEN-SPE-7059 describes the series as a High Strength, Buoyant STFOC™ Singlemode 9/125 cable with a proprietary strength layer, secondary buffer, and outside abrasion-resistant buoyant layer.

Product Overview

The LINDEN-SPE-7059-4 is suitable for underwater systems where standard fiber optic cables may be too fragile, too heavy, or unsuitable for repeated deployment. Its buoyant construction helps reduce drag and cable weight in water, while the high-strength internal design supports reliable use in towing, deployment, retrieval, and moving marine systems.

It is ideal for applications that require singlemode optical performance, mechanical strength, flexibility, and buoyancy in one compact cable design.

Key Features

• High-strength buoyant underwater fiber optic cable
• Designed for subsea, ROV, marine, tether, and harsh-environment use
• Singlemode fiber construction for long-distance optical transmission
• Buoyant outer layer to help reduce underwater cable weight
• Abrasion-resistant outer protection for rough handling and marine environments
• Proprietary strength layer for enhanced tensile performance
• Suitable for repeated deployment and retrieval applications
• Lightweight, flexible, and easier to handle than many conventional subsea cables
• Designed for reliable signal transmission in challenging underwater conditions

Technical Description

The LINDEN-SPE-7059-4 High-Strength Buoyant 2000 cable is engineered for applications where optical performance and mechanical durability are equally important. The cable combines a protected singlemode fiber core with a strong internal strength structure and a buoyant abrasion-resistant outer layer.

The buoyant jacket helps the cable remain more manageable in water, reducing the strain on underwater equipment and improving handling during deployment. The high-strength construction helps protect the fiber from tensile stress, bending, pulling, and operational movement.
