Outdoor-Indoor Optical Fiber Cable 4 fibers SM, SPAN up to 80 m, diameter 3 mm — electro base

Single-mode Outdoor-Indoor Optical Fiber Cable by electro base designed for short point-to-point links. The cable contains 4 single-mode fibers inside a compact 3 mm diameter jacket, suitable for runs between outdoor and indoor termination points with spans up to 80 m. Supplied on a 1000 m reel, this fiber cable is intended for telecommunications, network extensions, CCTV connections and indoor patching where a small-diameter, low-count single-mode fiber is required.

Advantages

The cable combines a rugged jacket suitable for limited outdoor exposure with an inner structure optimized for single-mode transmission, offering low attenuation over short spans. Its 3 mm diameter allows for easier routing through conduits and tight spaces compared with larger multi-fiber cables. The 4-fiber count provides simple point-to-point topology options and redundancy without unnecessary excess. Being supplied on a full 1000 m reel reduces handling joins and simplifies large installations.

Suitable for

• Short outdoor-to-indoor fiber links up to 80 m
• CCTV camera backbone and video distribution
• Telecommunications patching and network extensions
• Fiber to small buildings, cabinets or equipment rooms

Key specifications

• Fiber type: single-mode (SM)
• Number of fibers: 4
• Maximum recommended span: up to 80 m
• Cable outer diameter: 3 mm
• Suitable environments: outdoor and indoor (short outdoor exposure)
• Packaging: 1000 m reel

How to use

Route the cable along the planned path, observing bend radius limits typical for 3 mm single-mode fiber to avoid excess attenuation or mechanical damage. Terminate fibers with appropriate single-mode connectors or fusion splices in accordance with standard fiber handling procedures. Use weatherproof entry glands or transition points where the cable passes from outdoor to indoor environments, and secure the cable to prevent movement or mechanical strain. Test each fiber end-to-end with an appropriate optical light source and power meter or OTDR to verify continuity and loss within acceptable limits.

Usage recommendations

For reliable performance keep outdoor exposure limited to short runs and protect the cable from standing water, direct UV for prolonged periods, and mechanical abrasion. Maintain manufacturer-recommended minimum bend radius during installation and avoid tight coiling on the reel when deploying lengths to prevent microbending loss.
