INFRALAN Optical Fiber Cable A-DQ(ZN)B2Y OS2 24F (1x24) G657A1 black 5.8mm 2000N

INFRALAN Optical Fiber Cable A-DQ(ZN)B2Y OS2 24F (1x24) G657A1 black 5.8mm 2000N is a single-mode fiber cable designed for indoor and outdoor telecom and data networks. It contains 24 OS2 single-mode fibers arranged in a 1x24 configuration and uses G657A1 bend-insensitive fiber to maintain low attenuation in tight bends. The cable has a 5.8 mm outer diameter, black LSZH outer sheath suitable for varied installation environments, and a rated tensile strength of 2000 N (Fca) to provide mechanical protection during duct, conduit, or direct installation.

Advantages

This INFRALAN cable provides low-loss single-mode transmission with improved bend performance due to G657A1 fibers, reducing signal degradation in constrained routing paths. Its compact 5.8 mm diameter and robust outer sheath allow easier handling and installation in conduits and ducts while maintaining a high tensile rating for pull-in operations. The cable construction balances mechanical protection with space efficiency, making it suitable for backbone and distribution runs where single-mode performance and installation durability are required.

Suitable for

• Indoor/outdoor telecom and data networks where single-mode transmission is required
• Backbone and distribution fiber runs in ducts or conduits
• Installations requiring bend-resistant fibers (tight routing, cable trays, risers)
• Projects needing a compact cable with high tensile strength for pull-in

When it may not be suitable

The cable is optimized for single-mode OS2 applications and is not intended for multimode networking environments; using it where multimode optics are required will not match expected performance. It may also be unnecessary where extreme environmental protection (e.g., fully outdoor, direct-burial armoured requirements or repeated UV exposure) or specialized mechanical armor is required beyond the described sheath and 2000 N tensile rating.

Key specifications

• Fiber type: single-mode OS2
• Fibers: 24 (1x24 configuration)
• Fiber variant: G657A1 bend-insensitive fiber
• Outer diameter: 5.8 mm
• Sheath color: black (LSZH outer sheath)
• Tensile strength (installation): 2000 N (Fca)
• Intended installation: duct, conduit, indoor/outdoor backbone

How to use

Plan the cable route ensuring bend radii conform to G657A1 recommendations to preserve low loss. Use appropriate fiber installation tools and pulling techniques to avoid exceeding the 2000 N tensile limit during installation; apply steady pull forces and use lubricant where permitted for long duct pulls. Terminate fibers with compatible single-mode connectors and perform optical loss testing and end-face inspections after splicing or connectorization to verify link performance.

What to consider before purchase

• Confirm network needs for single-mode OS2 fiber versus multimode alternatives.
• Ensure 5.8 mm diameter and cable flexibility suit conduit or duct sizes in your installation.
• Verify required tensile rating for pull-in operations and expected installation stresses.
• Check bend radius constraints in routing paths to make use of G657A1 bend tolerance.

Usage recommendations

Follow manufacturer guidelines for minimum bend radius, avoid sharp bends during routing, and perform OTDR or insertion loss measurements after installation. Use appropriate cable clamps and strain reliefs at termination points and protect exposed fibers during fusion splicing to ensure long-term single-mode performance.
