24-core fiber optic cables for smart buildings are available from specialized manufacturers offering indoor and outdoor OM4/OS2 cables with LSZH or armored protection.

Key Manufacturers and Suppliers

1. Anteoptic – Offers both indoor and outdoor 24-core fiber optic cables. Outdoor cables are typically laminated or center bundle tube types, providing high protection and accommodating more cores. Indoor cables use a bundle structure (GJFJV model) with loose tubes, water-resistant filling, and optional steel wire or aluminum-polyethylene laminate for strength and water protection ( ).
2. GlobalSpec – Provides a wide range of 24-core fiber optic cables suitable for LAN, SAN, and data center applications. Cables include OM3 or OM4 multimode fibers, plenum-rated jackets, and MPO to LC duplex assemblies for high-speed 40/100G transmission ( ).
3. Voygar – Specializes in indoor tight-buffered 24-core OM4 multimode cables with LSZH jackets. The fibers are made of high-purity silica with germanium doping and UV-curable acrylate coatings, suitable for indoor smart building networks ( ).
4. Belden (GBWHF24) – Offers outdoor multi-loose tube 24-core single-mode OS2 cables with aramid yarns, steel wire armoring, and polyethylene jackets. These are designed for industrial backbones, campus networks, and direct burial installations, providing rodent protection and high mechanical strength ( ).

Cable Features for Smart Buildings

• Indoor Cables: LSZH jackets, tight-buffered or loose-tube structures, water-resistant filling, compact circular cores, and high flexibility for riser and horizontal cabling.
• Outdoor Cables: Laminated or center bundle tube types, armored or rodent-protected, UV-stabilized jackets, suitable for ducts, tunnels, and direct burial.
• Performance: OM4 multimode supports high-speed data transmission (40/100G), while OS2 single-mode ensures long-distance backbone connectivity.
• Strength and Protection: Steel wire or aluminum-polyethylene laminate for mechanical strength, hydrolysis-resistant tubes, and water-blocking compounds.

Considerations for Smart Building Deployment

• Indoor vs Outdoor: Choose indoor LSZH cables for fire safety and low smoke emission; outdoor armored cables for environmental protection.
• Fiber Type: OM4 multimode is ideal for high-speed LANs; OS2 single-mode is preferred for long-distance backbone connections.
• Installation: Ensure compatibility with building risers, conduits, and structured cabling standards. Some manufacturers provide pre-terminated MPO assemblies for faster deployment. These manufacturers and cable types provide reliable solutions for smart building networks, supporting high-speed data, IoT devices, and integrated building management systems.
