## Summary description

Single-mode INFRALAN optical fiber cable U-DQ(ZN)BH OS2 with 4 fibers arranged as 1x4, G.657.A1 bend-insensitive fibers and low-smoke zero-halogen (LSZH) black sheath. Rated Eca, tensile strength 3000 N. Designed for indoor and outdoor installations where OS2 single-mode performance, improved bending tolerance and flame/smoke-safe routing are required.

## Long description

The INFRALAN optical fiber cable U-DQ(ZN)BH OS2 4E (1x4) LSZH black G657A1 3000N is a single-mode communication cable engineered for installations requiring long-distance signal transmission with enhanced bend resistance and low smoke/halogen emissions. It contains four optical fibers arranged as 1x4, uses G.657.A1 bend-insensitive fiber geometry, and is sheathed in a black low-smoke zero-halogen material. The cable has a rated tensile strength of 3000 N and an Eca reaction-to-fire classification, making it suitable for combined indoor and protected outdoor routing where safety and optical performance are priorities.
Advantages
This cable provides single-mode OS2 performance with improved bending tolerance afforded by G.657.A1 fibers, which reduces signal loss in tight-routing scenarios. The LSZH jacket lowers toxic and corrosive gas release in the event of a fire, improving safety in enclosed spaces. The 3000 N tensile rating supports reliable tensile loading during installation, while the 1x4 fiber construction simplifies fiber splitting or direct termination for small distribution runs. The black sheath offers UV and dirt masking for visible outdoor-exposed sections when used in protected ducts or conduits.
Suitable for
Indoor backbone and riser installations in commercial and residential buildings
Protected outdoor runs in ducts, conduits or between buildings
Fiber-to-the-floor, fiber-to-the-desk, and small access aggregation points
Installations requiring bend-insensitive fiber routing in limited spaces
When it may not be suitable
This cable is designed for single-mode OS2 applications and is not appropriate for multimode networks or short-distance premises networks that rely on multimode optics. It is also intended for protected outdoor use; it is not a fully armoured or direct-burial cable, so it should not be used where mechanical damage, prolonged water immersion, or unprotected outdoor exposure are likely without additional protection.
Key specifications
Fiber type: single-mode, OS2
Fiber count and arrangement: 4 fibers in 1x4 configuration
Bend performance: G.657.A1 bend-insensitive fiber
Sheath material: LSZH (low-smoke zero-halogen)
Jacket color: black
Reaction to fire class: Eca
Tensile strength: 3000 N
How to use
Plan the route ensuring the cable remains within its minimum bend radius according to G.657.A1 guidance and avoid tight kinks. Use appropriate cable preparation tools to strip the LSZH jacket and buffer elements without nicking the fibers. For termination, follow standard single-mode splicing or connectorization procedures (fusion splicing or polished connectors) to maintain low loss. During installation, support the cable to avoid exceeding the 3000 N tensile rating and protect exposed sections with conduit or ducting when used outdoors. Perform optical power and continuity tests after installation to verify link performance.
What to consider before purchase
Confirm that single-mode OS2 fiber is compatible with your transceivers and link budget requirements
Assess whether the cable routing will require direct-burial, armouring, or additional environmental protection
Verify required fiber count and connectorization or splicing plan for your installation
Check local fire-safety codes to ensure Eca and LSZH meet building requirements
Usage recommendations
When routing this INFRALAN OS2 LSZH cable, maintain manufacturer-recommended bend radii, secure cable runs to prevent strain beyond 3000 N, and use fusion splicing for best single-mode loss performance. For outdoor-exposed segments, install the cable within ducts or conduits and avoid prolonged direct sunlight or standing water exposure.
