## Summary description

INFRALAN U-DQ(ZN)BH OS2 24E is a 24-core single-fiber optical cable designed for long-distance and backbone networks. It uses OS2 G.657.A1 fibers for low attenuation, a dry water-blocking (DQ) construction with non-metallic strength members (ZN) and a black LSZH outer jacket. Suitable for indoor/outdoor ducts and risers where low-smoke, halogen-free behavior and robust fiber performance are required.

## Long description

INFRALAN U-DQ(ZN)BH OS2 24E single-fiber 24-core optical cable, OS2 G.657.A1, LSZH black, 7.5 mm is a 24-core fibre optic cable designed for backbone and long-distance links. It combines low-loss OS2 G.657.A1 single-mode fibres with a dry water-blocking design and non-metallic strength members inside a black low-smoke, zero-halogen (LSZH) outer sheath. With a nominal outer diameter of 7.5 mm this cable is intended for use in ducts, risers and other indoor/outdoor transition applications where limited bend sensitivity and reduced fire hazard are required.
Advantages
The cable's OS2 G.657.A1 fibres deliver low attenuation and improved bend performance suitable for long-span and routed installations. The dry water-blocking construction prevents moisture ingress without gel, simplifying handling and splicing. Non-metallic strength members make the cable corrosion-resistant and non-conductive, enabling use near electrical equipment. The LSZH outer jacket reduces toxic and corrosive gas emission in case of fire, and the compact 7.5 mm diameter facilitates installation in constrained ducts and cable trays.
Suitable for
 Backbone and long-distance single-mode networks
 Indoor/outdoor duct installations and vertical risers
 Environments requiring low-smoke, zero-halogen cable jackets
 Installations near electrical equipment where non-metallic, non-conductive cables are preferred
 Routes with moderate bends where improved bend tolerance is beneficial
When it may not be suitable
This cable is designed as a single-mode fibre solution for backbone and distribution routes; it is not intended for multimode network applications. It is not armored, so it may not provide sufficient mechanical protection for direct burial in highly abrasive soils or areas with heavy rodent activity without additional conduits or protective measures.
Key specifications
 Fibre type: single-mode OS2 G.657.A1
 Number of fibres: 24 cores
 Construction: dry water-blocking (DQ) with non-metallic strength members
 Outer sheath: LSZH (low-smoke, zero-halogen), black
 Nominal outer diameter: 7.5 mm
 Intended use: indoor/outdoor ducts and risers
 Bend performance: G.657.A1 improved bend tolerance
How to use
Plan the cable route and confirm duct or tray capacity for a 7.5 mm diameter cable. Use appropriate pulling grips and maintain permissible tensile loads during installation to avoid exceeding the cable's maximum pulling force; follow standard installation practices for single-mode fibres. When preparing ends for splicing or connectorisation, remove the outer jacket and strength members carefully to expose the fibres, follow dry water-block handling procedures to clear blocking tapes or yarns, and perform fibre cleaning, cleaving and fusion splicing or connector termination according to manufacturer guidelines and industry standards.
What to consider before purchase
 Confirm single-mode OS2 G.657.A1 is compatible with your network transceivers and link budget
 Verify duct, tray and bend radius constraints for a 7.5 mm cable
 Assess whether additional mechanical protection (conduit or armoring) is needed for the installation environment
 Plan for connector types and splicing equipment required for 24 fibres
Usage recommendations
Maintain recommended minimum bend radius (as specified by the fibre standard) during installation and post-installation, avoid exceeding tensile limits when pulling, and store and handle reels in a dry, clean environment. For outdoor sections exposed to mechanical risks, consider routing within conduit or adding protective elements to extend service life.
