Fibre optic cable BlueOptics SFP9331FU2MK SN LC OM4 2 m Violet

The BlueOptics SFP9331FU2MK SN LC OM4 2 m Violet is a 2‑metre duplex multimode fibre optic patch cord designed for high‑speed InfiniBand and data centre interconnects. It uses laser‑optimized OM4 multimode fiber (G50/125 µm) for 850 nm transmission, with SN/UPC to LC/UPC connectors. The cable features a violet (magenta) LSZH jacket for low smoke and halogen‑free behaviour and is intended for reliable short‑reach optical links between patch panels, transceivers and switches.

Advantages

This OM4 patch cord offers low attenuation and high return loss suitable for demanding high‑density environments. Factory‑assembled components include zirconia ceramic ferrules and quality connectors that support up to 1500 mating cycles. Each assembly is tested using interferometry and OTDR and supplied with a measurement report of insertion loss and return loss values. The LSZH jacket reduces smoke and toxic gas emission in case of fire.

How to use

Route the duplex fibre so the jacket is not subject to tight bends; adhere to the manufacturer’s minimum bend radius for OM4 multimode cable. Remove dust caps from SN and LC connectors just prior to insertion and use appropriate cleaning tools if contamination is suspected. Plug the SN connector into the corresponding transceiver or adapter and the LC connector into the patch panel or second transceiver, ensuring correct polarity for Tx/Rx pairs. Avoid pulling on the connectors — use the cable jacket when positioning the cord.

Recommendations

For optimal performance, keep connector end faces clean and store spare dust caps when connectors are not in use. Use cable management and strain relief in dense racks to maintain bend radius and prevent microbending loss. Select OM4 patch cords of the appropriate length to minimize excess slack and insertion loss.
