Network Cable EFB Elektronik INFRALAN® A-DQ(ZN)B2Y OS2 12E 1x12 Eca 3000N LSZH black

The Network Cable EFB Elektronik INFRALAN® A-DQ(ZN)B2Y OS2 12E 1x12 Eca 3000N LSZH black is a single-unit fiber optic cable designed for backbone and horizontal distribution in indoor and duct installations. It uses G.657.A1 single-mode fibers (OS2-class) arranged in a 1x12 configuration with enhanced mechanical protection and a rated tensile strength of 3000 N. The LSZH (low smoke zero halogen) outer sheath and Eca fire classification make this cable suitable for installations where reduced smoke and halogen-free materials are required by safety regulations.

Advantages

The cable combines OS2 single-mode performance with G.657.A1 bend-insensitive fibers to maintain low attenuation in bent or routed installations. A tensile rating of 3000 N provides reliable mechanical robustness during installation and in pulled runs, while the LSZH sheath limits toxic and corrosive emissions in fire conditions. The Eca classification ensures compliance with common building fire-safety standards for non-plenum indoor use.

Suitable for

• Indoor backbone and horizontal fiber distribution
• Conduit and duct installations
• Data center interconnects and telecom rooms
• FTTx drop cables and building risers

Key specifications

• Fiber type: Single-mode G.657.A1 (OS2-class)
• Configuration: 1 x 12 fibers
• Outer sheath: LSZH (low smoke zero halogen)
• Fire performance: Eca (construction product classification)
• Tensile strength: 3000 N
• Color: Black
• Bend performance: Improved bend-insensitive characteristics

How to use

Install this fiber cable following standard fiber-optic installation practices: plan the route, avoid sharp bends and excessive pulling angles, and use suitable cable lubricants and pulling gear when necessary. Ensure cable bend radius limits are respected, secure the cable at regular intervals, and protect terminations with appropriate enclosures or patch panels. Perform optical inspection and testing (OTDR, insertion loss, end-face inspection) after installation to verify link performance.

Usage recommendations

Store the cable in a dry, dust-free environment prior to installation. When pulling, use the specified maximum tensile strength and observe recommended minimum bend radii for G.657.A1 fibers. Use compatible connectors and splicing methods to preserve OS2 performance and follow local fire-code requirements for LSZH and Eca-rated components.
