Fibre optic cable BlueOptics SFP9331FU0.5MK SN LC OM4 0.5m Violet

The BlueOptics SFP9331FU0.5MK SN LC OM4 0.5m Violet is a 0.5 metre duplex multimode fibre optic patch cord designed for high-speed InfiniBand and data centre connections. It uses OM4 (G50/125 µm) laser-optimized multimode fibre for reliable 850 nm signal transmission and comes with SN/UPC to LC/UPC connectors. The cable features a violet LSZH (low-smoke, zero-halogen) jacket and a compact length that suits short interconnects in patch panels, transceivers and switch ports.

Advantages

This OM4 patch cord provides low attenuation (approximately 2.5 dB/km) and high return loss, supporting error‑free short‑reach links. Connectors use zirconia ceramic ferrules and branded fibre cores to ensure stable transmission and a long mating cycle lifetime. The LSZH jacket reduces smoke and hazardous gas emissions in case of fire, and every unit is factory tested with interferometer and OTDR with an included measurement protocol.

Key specifications

How to use

Route the duplex patch cord between the transceiver and patch panel or between two transceivers, ensuring correct polarity and secure connector seating. Avoid sharp bends and maintain the minimum bend radius specified for OM4 fibre to prevent increased attenuation. When inserting or removing connectors, handle by the connector housing and protect the ferrule end faces with dust caps until connection to keep return loss and insertion loss within specified values.

Recommendations

Use this 0.5 m BlueOptics OM4 patch cord for short, high-density links inside racks or patch panels. Store and route the cable without tight bends, keep connector end faces clean, and verify performance using the included test protocol after installation. For longer runs select a suitable length variant to maintain low loss.
