## Summary description

The BlueOptics SFP3131BU5MK is a 5 m InfiniBand fibre optic cable featuring LC connectors. It utilizes G.657.A1 fibre type with a core diameter of 9 µm, ensuring full duplex communication. Ideal for high-speed data transmission in data centers and networking environments.

## Long description

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
 Environments requiring low-smoke, zero-halogen cabling
Key specifications
 Length: 5 m
 Connector type: Duplex LC/UPC to LC/UPC
 Fibre type: Single-mode G.657.A1 (9 µm core)
 Duplex full-duplex configuration
 Wavelengths supported: 1310 nm / 1550 nm
 Attenuation: approx. 0.4 dB/km
 Jacket: LSZH (low smoke zero halogen)
 Typical connector durability: up to 1500 mating cycles
 Factory tested with interferometer and OTDR; measurement protocol included
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.
