LEONI Kerpen LEONI LWL-Kbl 9µm OS2 Suhner LC/LC 5m - Kabel - 5 m

Data centre and enterprise networks demand reliable, high-bandwidth connectivity that can handle ever-increasing traffic without signal degradation. The LEONI Kerpen OS2 LC/LC Duplex Single-Mode Fibre Patch Cable delivers exactly that—a 5-metre, bend-insensitive single-mode fibre link engineered for 10G, 40G, and 100G Ethernet applications. With LC duplex connectors on both ends and a low-smoke zero-halogen (LSZH) yellow jacket, this cable provides a secure, future-proof connection for backbone cabling, server rooms, and telecom installations.

Who is it for

This patch cable is ideal for network engineers, data centre managers, and IT professionals who need a dependable, high-performance fibre link between switches, routers, servers, and patch panels. It suits organisations upgrading to high-speed Ethernet or deploying new fibre infrastructure where low insertion loss and high return loss are critical. The LSZH jacket makes it particularly suitable for enclosed spaces where fire safety and low toxicity are priorities.

Main features

• OS2 single-mode fibre with 9 µm core and 125 µm cladding for long-distance, high-bandwidth transmission.
• LC duplex connectors on both ends for easy, secure mating with standard SFP/SFP+ transceivers.
• Low insertion loss (< 0.3 dB) and high return loss (> 50 dB) ensure signal integrity.
• LSZH yellow jacket: low smoke, zero halogen, flame-retardant, and colour-coded for single-mode identification.
• Bend-insensitive design with minimum bend radius of 30 mm for flexible routing in tight spaces.
• Compliant with IEC 60793-2-50 Type B6.2 and TIA/EIA-568.3-D; RoHS compliant.

Tips

Always inspect connectors for dust before mating and use proper cleaning tools to maintain performance. Avoid exceeding the minimum bend radius during installation to prevent microbending losses. For best results, pair this cable with OS2-compatible transceivers and ensure polarity is maintained in duplex links.
