LEONI Kerpen LEONI LWL-Kbl 9µm OS2 Suhner LC/LC 20m - Kabel - 20 m

For installations where signal integrity over distance is non-negotiable, this LEONI Kerpen OS2 single-mode duplex patch cable delivers the low attenuation and precision alignment that multimode alternatives simply cannot match. The 9µm core and G.652.D fibre geometry ensure clean transmission at both 1310nm and 1550nm wavelengths, while factory-terminated LC/UPC connectors keep insertion loss below 0.3dB. At 20 metres, it bridges rack-to-rack or device-to-panel gaps without slack or tension.

Highlights

• Single-mode OS2 fibre (ITU-T G.652.D) with 9/125µm core/cladding
• Duplex LC/UPC to LC/UPC connectors, polished for low back reflection
• 20-metre length with LSZH jacket for low smoke and zero halogen safety
• Insertion loss < 0.3dB, return loss > 50dB per connector pair
• Attenuation ≤ 0.35dB/km @ 1310nm and ≤ 0.25dB/km @ 1550nm
• RoHS compliant and meets TIA/EIA-568-C.3 and IEC 61754-20

In daily use

This patch cable is built for long-haul backbone links, campus interconnects, or any environment where 10G, 40G, or 100G single-mode optics are deployed. The LSZH jacket emits minimal smoke and no halogen gases in the event of fire, making it suitable for data centres, healthcare facilities, and public buildings with strict safety codes. The duplex zip-cord design keeps both fibres organised, and the LC connectors click firmly into SFP/SFP+ transceivers, reducing the risk of accidental disconnects.
