BlueOptics SFP2121BU1MK InfiniBand fibre optic cable 1 m LC Yellow

The BlueOptics SFP2121BU1MK is a 1 m InfiniBand fibre optic patch cable with LC connectors and a single-mode G.657.A1 optical fibre. Designed for full-duplex transmission, this yellow LC–LC cable supports typical single-mode wavelengths (1310 nm / 1550 nm) and is intended for high-speed interconnects in data centres and networking environments. The cable is supplied with an LSZH flame-retardant jacket and factory-tested optical performance including attenuation and return-loss measurements.

Advantages

This 1 m BlueOptics cable offers low attenuation and high return loss values suitable for reliable single-mode links. Connectors use zirconia ceramic ferrules and branded components to ensure mechanical stability and a long mating-life. The LSZH outer jacket reduces smoke and halogen emissions in the event of a fire, meeting common industry safety norms. Each cable is tested with interferometer and OTDR methods and shipped with measurement results for insertion loss and return loss.

Key specifications

How to use

Inspect connectors and keep protective caps on until installation to avoid contamination. Route the 1 m patch cord through cable management to avoid tight bends and strain; adhere to the recommended minimum bend radius for single-mode G.657.A1 fibre. Insert the LC connectors into the corresponding LC ports on patch panels or transceivers until they click. Verify link continuity and optical loss using appropriate test equipment; use the supplied measurement protocol to compare factory values with in-situ readings.

Recommendations

Use the BlueOptics SFP2121BU1MK for short rack-to-rack or module-to-module connections where single-mode performance and LSZH safety are required. Avoid exceeding the specified bend radius and protect connector endfaces from dust; clean using fibre-optic approved cleaning tools if necessary. For custom lengths or polished-end requirements (UPC/APC), consult product options prior to purchase.
