The LINDEN-SPE-7107-20 Hybrid (-049) Buoyant Hybrid Cable is a specialist subsea and marine cable designed for applications where optical communication, electrical conductors, buoyancy, and mechanical reliability are required within a single rugged cable construction. Built for demanding underwater environments, this hybrid buoyant cable supports the transmission of fibre optic signals while also allowing electrical power or signal conductors to be integrated into the same cable assembly.

This cable is particularly suited for underwater systems where reduced weight in water, flexibility, and dependable performance are essential. Its buoyant design helps minimise drag and handling strain during deployment, recovery, and operation, making it suitable for remotely operated vehicles, underwater sensing systems, defence applications, oceanographic equipment, marine robotics, and subsea communication links.

Hybrid Cable Construction

The SPE-7107-20 Hybrid (-049) cable combines fibre optic elements with additional hybrid components, allowing it to serve multiple functions in one compact cable. The fibre optic component provides high-speed, low-loss data transmission, while the electrical or hybrid elements can be used for power, control, instrumentation, or signal requirements depending on the final cable configuration.

This integrated design helps reduce the need for multiple separate cables, improving system efficiency and simplifying installation. For underwater projects where space, weight, buoyancy, and reliability are critical, a hybrid cable offers a practical and robust solution.

Buoyant Performance

One of the key advantages of the LINDEN-SPE-7107-20 Hybrid (-049) cable is its buoyant construction. The cable is engineered to provide positive or near-neutral buoyancy in water, helping reduce downward load on underwater equipment. This is especially useful for tethered systems, floating marine platforms, ROVs, AUV support systems, and subsea monitoring equipment.

By reducing cable weight in water, the buoyant design helps improve manoeuvrability, reduce operational stress, and support smoother handling during deployment and retrieval.

Built for Marine and Subsea Environments

The cable is designed to perform in harsh marine conditions where standard cables may not be suitable. It is constructed to withstand exposure to water, movement, abrasion, repeated handling, and operational strain. Its durable outer jacket helps protect the internal fibre and hybrid components from mechanical damage while maintaining the flexibility needed for marine use.

The (-049) configuration indicates a specific cable design variation within the SPE-7107 series, allowing the cable to be matched to specialist application requirements. Final fibre count, conductor arrangement, jacket material, buoyancy level, strength member, and termination style can be adapted based on project needs.

Reliable Fibre Optic Communication

The fibre optic component within the cable supports fast and dependable data transmission over longer distances compared with traditional copper-only systems. This makes the cable suitable for applications requiring video, telemetry, sensor data, control signals, or real-time communication between surface equipment and underwater devices.

Depending on project requirements, the cable can be configured with singlemode or multimode optical fibres, different fibre counts, and suitable terminations.

Custom Configuration Options

Linden Photonics cable assemblies are often used in specialist applications where off-the-shelf cable products may not meet operational requirements. The SPE-7107-20 Hybrid (-049) can be adapted to suit different system designs, including variations in fibre type, conductor layout, jacket material, diameter, strength requirements, buoyancy level, and connector options.

This makes it a practical choice for engineers and system integrators who need a dependable custom hybrid cable for underwater use.
