Tight Buffer Optical Fiber Cables | Marine & Offshore LSOH FR Cables

IEC 60092-Series Cables Offshore Instrumentation and Signal Cable
Description

Product Overview

Our Tight Buffer Optical Fiber Cables are specifically engineered for reliable data transmission in demanding marine and offshore environments. These cables meet the highest safety standards with low smoke, zero halogen (LSZH), and fire retardant properties, making them ideal for use on ships and particularly in cruise ships where passenger and crew safety is paramount.

Key Features

  • Marine-Grade Safety: LSZH Fire Retardant sheath minimizes smoke and toxic emissions

  • Robust Construction: Designed to withstand harsh marine environments

  • Water Resistance: Reinforcing elements with watertight tape protection

  • Comprehensive Compliance: Meets international IEC standards for fire safety

  • Flexible Installation: Optimized bending radius for easy routing

  • Wide Temperature Range: Suitable for -20°C to +60°C operations

Applications

  • Data transmission networks on ships and vessels

  • Cruise ship communication and control systems

  • Offshore platform data links

  • Marine applications requiring enhanced fire safety (LSZH)

  • Shipboard data infrastructure

  • Naval communication systems
