Fiber optic cable 150 span

ADSS fiber optic cables are designed for self-supporting spans up to 150 meters, offering robust outdoor performance with single-mode G. 652 fibers.

Overview

A 150-meter span fiber optic cable is typically an ADSS (All-Dielectric Self-Supporting) cable, engineered to support itself between poles or structures without the need for metallic support elements. These cables are ideal for outdoor aerial installations, including campus networks, town-to-town links, and pole-to-building connections. They are lightweight, UV-resistant, and weatherproof, making them suitable for harsh environmental conditions such as wind, ice, and temperature fluctuations.

Construction and Features

Fiber Type: Most 150m span ADSS cables use single-mode G. 652. D fibers, which are bend-resistant and optimized for long-distance transmission.

Core Protection: Fibers are housed in loose tubes filled with water-blocking material, wrapped with aramid yarns for tensile strength, and extruded with a protective jacket (PVC or PE) for UV and moisture resistance. Central Strength Member: Many designs include a fiberglass-reinforced plastic (FRP) rod or similar central member to provide structural support and facilitate mid-span access. Fiber Count: Available in various configurations, commonly 24, 48, or up to 96 fibers, depending on network requirements.

Pre-

Termination: Some cables come pre-terminated with LC connectors, simplifying installation and reducing deployment time.

Span and Installation

Maximum Span: Designed for up to 150 meters between poles, ensuring stability under ice and wind conditions according to standards like NESC heavy. Deployment: Lightweight and self-supporting, these cables allow rapid and economical installation without additional support wires. Applications: Suitable for aerial outdoor networks, campus loops, and long-distance point-to-point links, providing reliable transmission in challenging environments.

AdvantagesSelf-supporting: No metallic elements required, reducing risk of electrical interference. Durable: Resistant to UV, moisture, and temperature variations. Flexible: Bend-resistant fibers allow easier handling and installation.

Scalable: Available in multiple fiber counts and lengths, typically sold in kilometers for large deployments. In summary, 150-meter span ADSS fiber optic cables provide a robust, self-supporting solution for outdoor fiber networks, combining durability, ease of installation, and high-performance single-mode fibers suitable for long-distance communication.
