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.

Suitable for

• Short-range InfiniBand and fibre interconnects within racks and patch panels
• Connecting optical transceivers and patch panel ports using LC connectors
• Single-mode network links operating at 1310 nm or 1550 nm
• Data centre and enterprise networking installations requiring LSZH jackets

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.

Usage 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.
