## Summary description

Tight-buffered multi-tube single-mode fiber cable INFRALAN U-DQ(ZN)BH OS2 48E (4x12) with 48 OS2 fibers arranged as 4 tubes of 12. Features G.657.A1 bend-insensitive fibers, LSZH outer sheath, black jacket and an 11.2 mm diameter. Designed for indoor/outdoor duct and backbone installations where low-smoke, halogen-free routing and reliable long-distance single-mode transmission are required.

## Long description

INFRALAN U-DQ(ZN)BH OS2 48E (4x12) is a tight-buffered multi-tube single-mode fiber cable designed for backbone and duct installations where low-smoke, halogen-free materials and bend-insensitive transmission are required. The cable contains 48 OS2 fibers arranged as four tubes with 12 fibers each, uses G.657.A1 bend-insensitive fiber types for improved routing around tight bends, and is protected by a black LSZH outer sheath. With an 11.2 mm overall diameter and construction suited to indoor/outdoor runs, it supports long-distance single-mode links and structured network backbones.
Advantages
The cable’s use of G.657.A1 bend-insensitive fibers reduces microbend and macrobend losses, simplifying installation in constrained spaces and improving long-term signal reliability. The tight-buffered multi-tube design allows organized fiber distribution and easier breakout for splicing or termination. The LSZH outer jacket minimizes toxic fumes and smoke in case of fire, making the cable suitable for confined or public spaces. Its 11.2 mm diameter balances mechanical strength and flexibility for duct, conduit, and riser pathways.
Suitable for
Indoor/outdoor duct and conduit backbone installations
Data center riser and interbuilding single-mode links
Areas requiring low-smoke, halogen-free cabling (public buildings, tunnels)
Environments with limited bend radii or tight routing paths
When it may not be suitable
This cable is optimized for single-mode long-distance transmission and structured backbone routes; it is not intended for short-distance multimode networks or premises horizontal cabling where multimode fibers are preferred. If armoring or extreme mechanical protection is required for direct burial without additional conduit or duct, a specially armoured or outdoor-rated cable should be chosen instead.
Key specifications
Fiber type: single-mode, ITU-T G.657.A1 bend-insensitive
Fiber count and arrangement: 48 fibers arranged as 4 tubes × 12 fibers
Construction: tight-buffered multi-tube
Outer sheath material: LSZH (low smoke, zero halogen)
Jacket color: black
Outer diameter: 11.2 mm
Intended use: indoor/outdoor duct, backbone and riser installations
How to use
Plan the route to maintain minimum bend radius recommendations for G.657.A1 fibers, route the cable through ducts or conduits avoiding sharp edges, and secure the cable at appropriate intervals. For termination, perform controlled breakout of the tight-buffered tubes, identify and prepare individual fibers for fusion splicing or connector termination following standard fiber handling practices. Use proper stripping tools, cleaning solvents, and splice protectors. Test end-to-end loss and continuity after installation with an optical power meter and/or OTDR appropriate for single-mode OS2 fibers.
What to consider before purchase
Confirm single-mode OS2 fiber is compatible with existing transmission equipment and link budget requirements
Verify required fiber count and tube organization match splicing and patching plans
Ensure LSZH jacket and 11.2 mm diameter meet routing space and fire-code requirements for your site
Assess whether additional mechanical protection or armoring is needed for the intended installation method
Usage recommendations
Follow manufacturer-recommended minimum bend radii for G.657.A1 fibers during installation and maintenance, keep pulling tensions within specified limits, and perform post-installation optical testing to validate attenuation and continuity. Use proper labeling and documentation for each tube and fiber to simplify future moves, adds, and changes.
