LINDEN-SPE-7110-7 Hybrid (-054) Buoyant Hybrid Cable
LINDEN-SPE-7110-7 Hybrid (-054) Buoyant Hybrid Cable is a lightweight, rugged hybrid fiber optic and copper cable designed for marine and subsea applications. It combines high-speed optical communication with electrical power/control conductors and features a buoyant construction for underwater deployment, including ROVs, robotics, and sensor systems.
Description
I could not find a publicly available specification sheet specifically titled LINDEN-SPE-7110-7 Hybrid (-054). The available Linden Photonics documentation lists the related LINDEN-SPE-7110 Hybrid family specification, but the “-7” buoyant variant appears to be a specific configuration that may require a manufacturer datasheet or quotation.
Based on the available LINDEN-SPE-7110 Hybrid specification information, the cable family details are:

| Optical Fiber | 1 × Singlemode (SM) fiber |
| Copper Conductors | 3 × #16 AWG conductors |
| Nominal Cable Diameter | 13 mm |
| Ultimate Tensile Strength (UTS) | 450 lb (listed for LINDEN-SPE-7110 family) |
| Buoyancy | Buoyant version (-054) — specific buoyancy value not publicly listed |
| Cable Construction | Linden proprietary rugged hybrid construction |
| Intended Environment | Harsh-environment, marine, subsea, ROV, robotics, and specialty tether applications |
Key Design Features
- Hybrid capability: Combines optical data transmission with electrical power/control conductors in one cable assembly.
- Buoyant construction: Designed for underwater applications where reduced cable weight in water or controlled buoyancy is important. Linden offers buoyant designs ranging from positive buoyancy to neutral buoyancy depending on application requirements.
- Rugged mechanical design: Linden hybrid cables use specialized jacket and strength-member technologies intended for demanding environments, including moisture exposure, mechanical loading, and repeated deployment.
- Marine/ROV suitability: Typical uses include ROV tethers, underwater robotics, sensing systems, and subsea communication links.
Typical Applications
- Remotely Operated Vehicle (ROV) tether systems
- Underwater robotics
- Marine sensor networks
- Subsea monitoring equipment
- Lightweight power + fiber communication links
- Defense and industrial underwater systems
Notes on Missing “-054” Data
For the exact LINDEN-SPE-7110-7 (-054) variant, the following values should be confirmed from Linden’s controlled drawing/specification:
- Exact buoyancy / specific gravity
- Jacket material and color
- Weight in air and water
- Safe working load (SWL)
- Minimum bend radius
- Voltage/current rating of conductors
- Fiber attenuation values
- Temperature and depth ratings
Linden provides custom specifications and drawings for these cable variants through its technical documentation and quotation process.
