LINDEN-SPE-7077 High-Strength Buoyant 450 MM (50um)
LINDEN-SPE-7077 is a compact high-strength buoyant multimode 50/125 fiber optic cable designed for underwater, marine, ROV, tethered, and subsea optical communication applications. It features a 3.5 mm outside diameter, one multimode fiber, buoyant construction, and 450 lb tensile strength.
Description
LINDEN-SPE-7077 is a high-strength buoyant multimode fiber optic cable designed for underwater and harsh-environment applications where compact size, controlled buoyancy, flexibility, and dependable tensile performance are important. This cable uses multimode 50/125 fiber, has a 3.5 mm / 0.137 inch approximate outside diameter, and is listed with a 450 lb / 205 kg ultimate tensile strength.
The cable is part of Linden Photonics’ buoyant STFOC™ cable family and is suitable for subsea, marine, tethered, and deployable systems where a lightweight optical cable is required without the handling problems of heavier conventional underwater cables. Linden’s buoyant cable designs are promoted for underwater uses such as ROV controls, mooring buoys, and other tethered applications.
Product Overview
The LINDEN-SPE-7077 is built for applications that need multimode optical transmission in a buoyant, rugged, and compact cable format. Its 50/125 multimode fiber supports short-to-medium distance data transmission, while the buoyant outer construction helps the cable perform in water-based environments where cable weight, drag, and handling are key concerns.
This model is described as a Buoyant STFOC™ Multimode 50/125 cable with one fiber, a proprietary strength layer, secondary buffer layers, and an outside abrasion-resistant buoyant layer.

Detailed Description
The LINDEN-SPE-7077 High-Strength Buoyant 450 MM 50um cable is engineered for optical communication in underwater and demanding field environments. It combines a compact 3.5 mm cable profile with a buoyant construction, helping reduce sinking weight and improving handling during deployment, retrieval, and in-water operation.
Its multimode 50/125 fiber makes it suitable for systems that require robust optical data transfer over practical working distances. The cable’s 450 lb tensile strength rating gives it the mechanical strength needed for demanding use while keeping the cable flexible and manageable.
The product’s buoyant jacket design is especially useful where the cable must remain easy to control in water, reduce drag, or avoid excessive downward load on connected equipment. Linden’s broader buoyant cable technology supports density control for positive, neutral, or negative buoyancy depending on design requirements.
Typical Applications
LINDEN-SPE-7077 can be used in:
- ROV and underwater vehicle tether systems
- Marine research and oceanographic equipment
- Subsea sensors and monitoring systems
- Buoyant optical communication links
- Mooring buoy connections
- Defense, inspection, and underwater instrumentation systems
- Lightweight deployable fiber optic systems
