Fibre optic cable BlueOptics SFP3131BU2MK — OS2 singlemode 2 m, LC–LC, 9 µm, full duplex

BlueOptics SFP3131BU2MK is a 2 m single-mode (OS2 / G.657.A1) fibre optic patch cord with duplex LC/UPC connectors and a 9/125 µm laser-optimized glass core. The yellow LSZH-jacketed cable is designed for full-duplex transmission of 1310 nm and 1550 nm signals and is intended for connecting optical transceivers, switches or patch panel ports with low insertion loss.

Advantages

The cable offers low attenuation (0.4 dB/km specified) and high return loss, with connector polish options available to further optimise return loss. High-quality branded glass fibres and manufacturer-grade connectors with zirconia ceramic ferrules are used to ensure reliable, low-loss transmission and a long mating lifecycle. Each cable is factory-tested (interferometer and OTDR) and shipped with a measurement protocol for insertion loss and return loss.

Key specifications

How to use

Inspect connectors and cable for visible damage before installation. Plug LC connectors into the optical transceivers or patch panel ports until they click securely. Maintain bend radius guidelines and avoid tight bends or kinks in the fibre. For link verification, compare the supplied measurement protocol with in-situ insertion loss and return loss measurements after installation.

Recommendations

Store and handle the LSZH cable in a clean environment, avoid contaminating connector endfaces, and clean ferrules with appropriate fibre cleaning tools before mating. For custom lengths or specific connector polish (UPC/APC) requests, contact the supplier.
