The model of the outdoor 24-pair optical cable can be Corning ALTOS® Loose Tube Gel-Free 24F OS2 or similar variants like CommScope 24 Fiber OS2 Loose Tube, depending on manufacturer and specifications.

Corning ALTOS® 24-Fiber Cable

The Corning ALTOS® cable is a 24-fiber, single-mode (OS2), all-dielectric, gel-free loose tube cable designed for outdoor and limited indoor use in aerial and duct installations. It features water-swellable materials for full water blocking, flexible buffer tubes for easy routing, and a medium-density polyethylene (MDPE) jacket that is rugged and easy to strip. The cable is suitable for backbone applications and does not require bonding or grounding (Corning ALTOS®) .

CommScope 24-Fiber OS2 Loose Tube

The CommScope 24-fiber OS2 loose tube cable is an all-dry, all-dielectric, gel-free outdoor cable suitable for direct burial, aerial, and conduit applications. It uses dry water-blocking elements, reduced-diameter buffer tubes, and a MDPE jacket (with optional HDPE). The fibers are color-coded for easy identification, and the cable eliminates the need for filling gels, simplifying installation and improving cleanliness in the work environment .

Other 24-Fiber Outdoor Cable Options

• Belden GOENE24: Outdoor central loose tube, jelly-filled, 24 fibers MM OM4, with glass yarns for strength and a polyethylene outer jacket plus termite protection .
• Legrand 24-Core OS2 Loose Tube: Features corrugated steel tape armoring for rodent protection, MDPE jacket, suitable for direct burial and outdoor installation .
• GYTS 24-Core Fiber Optic Cable: Stranded steel tape cable with PBT loose tubes, filling compound, and MDPE outer jacket, suitable for duct and aerial applications .

Key Considerations

When selecting a 24-pair outdoor optical cable, consider:

• Fiber type: Single-mode (OS2) for long-distance backbone or multimode (OM4) for high-speed LAN.
• Construction: Loose tube vs central tube, gel-free vs jelly-filled.
• Environmental protection: Water-blocking, rodent-proofing, UV resistance.
• Installation method: Aerial, duct, or direct burial. The exact model depends on the manufacturer and specific application requirements, but Corning ALTOS® 24F OS2 and CommScope 24 Fiber OS2 Loose Tube are widely used standard models for outdoor 24-pair optical cabling.
