Outdoor Two-Core Optical Cable

A 2-core outdoor optical cable is typically a singlemode fiber designed for FTTH or OSP applications, offering environmental protection, UV resistance, and mechanical strength for aerial, duct, or direct-burial installation.

Key Features

Fiber Type: Most 2-core outdoor cables are singlemode (OS2), suitable for long-distance transmission and FTTH networks, with low attenuation and bend-insensitive properties (G. 657. A2 standard) for flexible routing.

Construction: Sheathing: Outdoor cables often use PE (polyethylene) jackets for UV and weather resistance, with some models being LSZH (Low Smoke Zero Halogen) for safety. Strength Members: Aramid yarn or central strength members provide tensile strength for pulling and aerial installation. Water Protection: Some cables include gel-filled or water-blocked designs to prevent moisture ingress.

Armoring: Optional armored cables are available for direct burial or rodent protection, while dielectric (metal-free) versions are used near high-voltage lines. Mechanical Properties: Designed to withstand crush, impact, and bending during installation. Can be installed in ducts, microducts, or aerially with or without a supporting messenger wire.

Connectors and Termination: Some 2-core FTTH drop cables come pre-terminated with LC/APC connectors on one end for easy connection to wall boxes or terminals, while the other end may have a pulling aid for installation. Standards Compliance: Compliant with TIA 568-C. 3-1, CE, RoHS, and FCC standards, ensuring quality and reliability.

Meets FTT

H and outdoor deployment requirements, including anti-UV and environmental durability. Typical ApplicationsFTTH networks: Connecting distribution points to homes or buildings. Aerial installation: Suspended between poles using a supporting wire.

Duct or conduit deployment: Underground or inside buildings, including riser ducts. Direct burial: Armored versions for outdoor underground installation.

Summary

A 2-core outdoor optical cable is a lightweight, durable, and weather-resistant solution for small-scale fiber deployments, particularly in FTTH or short-range OSP networks. It combines singlemode fiber performance with mechanical and environmental protection, making it suitable for aerial, duct, or direct-burial installations, and can be pre-terminated for faster deployment.
