BlueOptics SFP3131BU5MK InfiniBand fibre optic cable 5 m LC Yellow

BlueOptics SFP3131BU5MK is a 5 m InfiniBand duplex fibre optic patch cable with LC/UPC connectors and single-mode G.657.A1 fibre (9 µm core). The yellow, LSZH-jacketed cable is designed for full-duplex high-speed data transmission at common wavelengths (1310 nm / 1550 nm) and for connecting transceivers, patch panels and other optical equipment in data centre and networking environments. Each cable is factory-tested with interferometer and OTDR and supplied with measured insertion loss and return loss values.

Advantages

The cable uses laser-optimized single-mode fibre with low attenuation (approx. 0.4 dB/km) and high return loss potential depending on connector polish. High-quality branded fibre and precision connectors with zirconia ceramic ferrules provide consistent optical performance and up to 1500 mating cycles. The LSZH jacket reduces smoke and eliminates halogen release in case of fire, helping meet common industry safety norms.

Suitable for

• InfiniBand and fibre channel links in data centres
• Interconnection of optical transceivers and patch panels
• High-speed point-to-point links at 1310 nm or 1550 nm

How to use

Install the BlueOptics SFP3131BU5MK by securely inserting the LC connectors into the corresponding LC ports on transceivers or patch panels, ensuring correct orientation for duplex links. Route the cable to avoid sharp bends and mechanical strain; maintain the minimum bend radius specified by the equipment manufacturer. Verify link parameters using the supplied measurement protocol or perform an in-place OTDR/ insertion loss test after installation to confirm expected performance.

Usage recommendations

Store and handle the cable by the connector boot and avoid touching the ferrule endfaces. Clean connector endfaces before mating using appropriate fibre cleaning tools. For installations in cabinets and conduits, respect bend-radius limits and avoid tensile loading; for safety-sensitive environments choose the LSZH variant to minimize smoke and halogen emissions in case of fire. If custom lengths or different connector polishes are required, request a tailor-made variant to match system return-loss requirements.
