Fibre optic cable BlueOptics SFP9331FU7.5MK SN LC OM4 7.5 m Violet

The BlueOptics SFP9331FU7.5MK SN LC OM4 7.5 m Violet is a duplex multimode fiber optic patch cord designed for high-speed InfiniBand and data centre connections. It uses laser-optimized OM4 multimode fiber (50/125 µm) in a 7.5 m length with SN (SN/UPC) to LC (LC/UPC) connectors and a violet (magenta) LSZH jacket. Engineered for 850 nm transmission, the cable provides low attenuation and consistent return loss, and is compatible with patch panels, optical transceivers and other SN- or LC-equipped network components.

Advantages

The cable combines OM4 LOMMF fiber for improved modal bandwidth with precision-manufactured SN and LC connectors to ensure stable, low-loss connections. Its LSZH (low smoke zero halogen) outer jacket reduces smoke and toxic emissions in case of fire and improves safety in confined installations. Connectors use zirconia ceramic ferrules and brand components to provide reliable mating cycles and consistent optical performance. Each unit is tested with interferometry and OTDR and supplied with measurement data for input loss and return loss.

Key specifications

How to use

Connect the SN duplex end to the compatible SN/UPC port on the transceiver or patch panel and the LC duplex end to the corresponding LC/UPC port, ensuring correct polarity for duplex links. Handle the cable by the connectors and avoid sharp bends to maintain the minimum bend radius of multimode fiber. Use the supplied measurement protocol to verify end-to-end insertion loss and return loss after installation. For best performance, keep connector endfaces clean and protect unused ports with dust caps until connection.

Recommendations

Store and install the cable in environments within manufacturer-recommended temperature and humidity ranges, avoid tight bundling and sharp bends, and always perform end-to-end optical testing after installation. Use LC-compatible adapters or patch panels when connecting to LC ports and follow established fiber handling and cleaning procedures to maintain low insertion loss and high return loss.
