LINDEN-SPE-7098-7 High-Strength Buoyant 750
LINDEN-SPE-7098-7 High-Strength Buoyant 750 is a rugged singlemode buoyant fiber optic tether designed for subsea communication, ROV systems, marine research, underwater inspection, and harsh-environment applications. With a compact 3.5 mm diameter and 750 lb tensile strength, it provides a strong, lightweight, and reliable solution for demanding underwater fiber optic deployments.
Description
The LINDEN-SPE-7098-7 High-Strength Buoyant 750 is a rugged buoyant fiber optic tether designed for underwater communication, subsea inspection, ROV operations, marine research, and demanding field applications where strength, flexibility, and reliable optical performance are required.
This cable is part of Linden Photonics’ high-strength buoyant cable range and is built for environments where standard fiber optic cables may be too fragile, too heavy, or unsuitable for repeated deployment in water. The available Linden specification for LINDEN-SPE-7098 lists a 3.5 mm outside diameter, singlemode fiber, 750 lb tensile strength, and attenuation values of <0.45 dB/km at 1310 nm and <0.35 dB/km at 1550 nm.
Product Overview
The LINDEN-SPE-7098-7 High-Strength Buoyant 750 is designed for applications where a compact and lightweight fiber optic cable must also deliver high mechanical strength. Its buoyant construction helps reduce drag and handling difficulty in underwater deployments, while the high-strength design supports demanding marine use.
This cable is suitable for long-distance underwater data transmission, remote sensing, inspection systems, and tethered equipment where low optical loss and dependable mechanical performance are important.
