Glasvezel-patchkabel BlueOptics SFP3131BU3MK 3 m OS2 LC–LC geel, 9 µm, vollduplex

BlueOptics SFP3131BU3MK is a 3 m single‑mode (OS2 / G.657.A1) fibre optic patch cord with duplex LC/UPC connectors on both ends. The yellow, 9 µm core cable is laser‑optimized for 1310 nm and 1550 nm transmission and is intended for reliable low‑loss interconnection of patch panels, optical transceivers and other single‑mode links in data centres, telecom and server environments.

Advantages

The cable features a flame‑retardant LSZH jacket for reduced smoke and no halogen release in case of fire. It delivers low attenuation (0.4 dB/km typical), low insertion loss and high return loss; connector polish options (UPC or 8° APC) allow further return‑loss optimization. Branded single‑mode fibres (e.g. Corning, Fujikura, YOFC) and precision zirconia ferrules provide high reliability and up to 1500 mating cycles. Each unit is tested with interferometer and OTDR and shipped with measured insertion‑loss and return‑loss values.

Key specifications

How to use

Route the duplex LC‑LC patch cord between the required LC ports of patch panels, switches or transceivers, taking care to maintain the correct transmit/receive orientation. Avoid tight bends and mechanical stress on the cable and secure it with appropriate cable management to prevent excess strain. If custom length or alternate connector polish is required, order accordingly before deployment.

Recommendations

Store and install the cable in a clean environment to keep connector endfaces free of dust and contaminants; inspect and clean connectors with appropriate fibre‑optic cleaning tools before mating to ensure optimal insertion loss and return loss performance.
