Alantec fiber optic cable OS2 outdoor Z-XOTktdD SM 4J 9/125 PE

Alantec fiber optic cable OS2 outdoor Z-XOTktdD SM 4J 9/125 PE is a single-mode outdoor cable designed for long-distance and external installations. The cable contains four OS2 single-mode fibers with 9/125 µm core/cladding, enclosed in a weather-resistant polyethylene (PE) outer sheath. It is engineered for use in aerial, duct or direct-buried deployments where environmental protection and stable single-mode optical transmission are required.

Advantages

This cable provides low attenuation and consistent single-mode performance across long distances thanks to OS2 fibers with 9/125 µm geometry. The robust PE outer sheath offers mechanical protection and resistance to UV, moisture and common outdoor hazards. The cable design supports multiple outdoor deployment methods—air, duct or direct burial—reducing the need for different product types across a network. Compact construction with four fibers keeps routing and handling simple in distribution points and trunk lines.

Suitable for

• Long-distance single-mode optical links between buildings and across campus networks
• Aerial installations on messenger wires or poles
• Installation in underground ducts and conduits
• Direct-buried runs where a weather-resistant PE sheath is required

Key specifications

• Fiber type: OS2 single-mode
• Number of fibers: 4
• Core/cladding diameter: 9/125 µm
• Jacket material: polyethylene (PE)
• Suitable deployment: aerial, duct, direct-buried
• Primary use: outdoor long-distance signal transmission

How to use

Prepare cable entry points and follow standard fiber handling procedures to avoid microbending or contamination. Use appropriate cable preparation tools to strip the PE sheath and expose the fiber buffer tubes without nicking the fibers. When splicing or terminating, maintain clean connectors and follow manufacturer-recommended splice loss budgets for OS2 single-mode fibers. Secure the cable in aerial spans, duct runs or burial trenches according to local installation codes, ensuring proper bend radii and mechanical protection at transition points.

Usage recommendations

For best long-term performance, use designated outdoor splice closures and weatherproof terminations, protect direct-buried sections with sand bedding or conduit where required, and avoid tight bends or excessive tensile loads during installation. Regular inspection of aerial supports and connections is advised to maintain signal integrity.
