BlueOptics SFP3233FU1MK InfiniBand fibre optic cable 1 m SC ST OM4

The BlueOptics SFP3233FU1MK InfiniBand fibre optic cable is a 1 m duplex patch cord with SC/UPC on one end and ST/PC on the other, designed for multimode OM4 fibre (50 µm core). Magenta-coloured and optimized for 850 nm operation, this cable provides a standard solution for short-reach, high-bandwidth connections between patch panels, transceivers and active networking equipment. The cable uses a flame-retardant LSZH jacket and is intended for environments where low smoke and halogen-free performance is required.

Advantages

The OM4 multimode fibre provides improved bandwidth and lower attenuation compared with lower-grade multimode fibres, supporting high-speed InfiniBand data transmission. SC and ST connectors with zirconia ceramic ferrules ensure stable optical alignment and durability, with connector lifetimes rated up to typical industry mating cycle counts. Production testing with interferometer and OTDR confirms low insertion loss and high return loss, and each cable ships with measured loss values.

Suitable for

• Connecting InfiniBand transceivers and switches in data centres and compute clusters
• Patch panel to transceiver or patch panel to patch panel short-reach links
• High-speed server-to-switch or switch-to-switch multimode links
• Environments requiring flame-retardant, low-smoke, halogen-free cabling

Key specifications

• Fibre type: OM4 multimode (50/125 µm)
• Length: 1 m
• Connectors: Duplex SC/UPC to ST/PC
• Operating wavelength: 850 nm (laser-optimized multimode)
• Jacket: LSZH (low smoke zero halogen), magenta colour
• Typical attenuation: approx. 2.5 dB/km
• Duplex/full duplex configuration for bidirectional links
• Connector ferrule: zirconia ceramic for accurate alignment

How to use

Inspect connector endfaces before installation and keep protective caps in place until connection. Plug the SC connector into compatible SC ports and the ST connector into ST ports or transceivers, ensuring correct orientation and secure latching. Route the cable without tight bends and avoid stress at connector boots; maintain the manufacturer’s minimum bend radius for multimode OM4 fibre. After installation, verify link integrity with appropriate optical test equipment and consult the supplied measurement protocol for insertion and return loss values.

Usage recommendations

For reliable performance, use this 1 m OM4 patch cord in short-reach, high-bandwidth multimode links operating at 850 nm. Store and handle connectors using dust caps, avoid kinks and excessive pulling forces, and perform periodic inspection and cleaning of endfaces to maintain low insertion loss and return loss.
