Wentronic Goobay 59640 OS2 Single-Mode Fiber Optic Patch Cable, SC/APC to SC/APC, 3 m, Yellow

FTTH installations demand low-loss, high-return-loss connections that can handle the tight bend radii of in-home routing. The Wentronic Goobay 59640 fiber optic patch cable answers that need with a 3-meter OS2 single-mode simplex link, terminated with SC/APC connectors on both ends. Its yellow jacket follows the industry colour code for single-mode fibre, making it instantly identifiable in crowded patch panels or ONT cabinets.

Who is it for

This cable is built for telecom technicians, FTTH installers, and network administrators who need a dependable, low-attenuation jumper between an optical network terminal (ONT) and a wall outlet, or between fibre distribution frames in a data centre. It is equally suited for service providers rolling out GPON or XGS-PON last-mile connections, where APC polishing is mandatory to minimise back reflections.

Main features

• OS2 single-mode fibre (ITU-T G.652.D) with 9/125 µm core/cladding for long-haul and access networks.
• SC/APC connectors on both ends: angled physical contact polish reduces return loss to ≥60 dB, critical for high-speed PON systems.
• 3-metre length offers flexibility for in-room or rack-to-rack patching without excess slack.
• Yellow LSZH jacket provides halogen-free safety and clear single-mode identification.
• Simplex construction keeps the cable slim and easy to route through narrow conduits.
• Low insertion loss (≤0.3 dB typical) ensures minimal signal degradation across the link.

Tips

Always clean both connector end faces with a one-click cleaner before mating to avoid contamination-induced loss. For FTTH deployments, pair this patch cable with an APC-compatible optical power meter to verify link budget. Store excess length in a figure-eight loop rather than tight coils to maintain bend radius and signal integrity.
