## Summary description

Alantec OM4 multimode fiber optic cable, 50/125 µm core/cladding, 24 fibers (24G) in universal U-DQ(ZN)BH construction with LSOH jacket and B2ca flame-retardant rating. Designed for high-speed data and enterprise networks, backbone and horizontal links, and indoor installations requiring low-smoke zero-halogen sheath and improved fire performance.

## Long description

Alantec OM4 MM 50/125 LSOH 24 cores U-DQ(ZN)BH B2ca FireHardy universal is a multimode fiber optic cable designed for high-speed data transmission in structured networks. The cable uses OM4 grade 50/125 µm multimode fibers arranged in a 24-core configuration within a universal U-DQ(ZN)BH construction. It features a low-smoke zero-halogen (LSOH) outer sheath and meets enhanced fire performance with a B2ca rating, making it suitable for indoor backbone and horizontal installations where improved fire safety and minimal smoke emission are required.
Advantages
This fiber optic cable combines OM4 multimode fiber performance with a universal loose tube design that simplifies installation in mixed indoor routing scenarios. The LSOH jacket reduces toxic halogen and smoke generation in the event of a fire, and the B2ca fire performance classification provides a higher level of flame retardance for building installations. The 24-core count supports dense multi-fiber connectivity for data centers, enterprise backbones and campus networks while maintaining the bandwidth and modal properties associated with OM4 fibers.
Suitable for
High-speed enterprise and data centre intra-building links
Backbone and horizontal cabling in commercial and public buildings
Areas requiring low-smoke zero-halogen materials and improved fire performance
Multi-fiber trunks, patch panels and breakout assemblies
Key specifications
Fiber type: OM4 multimode, 50/125 µm core/cladding
Number of fibers: 24 cores
Construction: universal U-DQ(ZN)BH loose tube design
Outer sheath: low-smoke zero-halogen (LSOH)
Fire performance: B2ca classification
Designed for indoor backbone and horizontal installations
How to use
Route the cable following building cabling standards and local fire safety regulations. Use appropriate cable management accessories such as trays, conduits and bend-radius protectors to avoid microbends and macrobends that can impair multimode performance. For termination, prepare fibers with manufacturer-recommended cleaning and polishing procedures or use factory-terminated connectors and splice in controlled environments. Ensure strain relief and secure fastening at splice closures and patch panels to prevent mechanical stress on the fibers.
Usage recommendations
For optimal performance, maintain minimum bend radii as specified for multimode loose tube cables, avoid compressive loads during installation, and store the cable in a dry environment prior to deployment. Choose connectors and transceivers matched to OM4 multimode characteristics to achieve stated bandwidth and distance performance in network designs.
