Fibre optic cable BlueOptics SFP9331FU3MK SN LC OM4 3 m Violet

BlueOptics SFP9331FU3MK SN LC OM4 3 m Violet is a 3-meter duplex multimode fibre optic patch cord designed for high-speed InfiniBand and data centre interconnects. The cable uses OM4 laser-optimized multimode fibre (50/125 µm) for transmission at 850 nm, and comes with SN/UPC to LC/UPC connectors in a violet (magenta) jacket. The cord features a low-smoke, zero-halogen (LSZH) jacket and is intended for reliable short-range links between patch panels, transceivers and active equipment.

Advantages

This OM4 patch cord offers low attenuation (typically 2.5 dB/km) and high return loss for stable, low-loss links in high-density environments. Connectors use zirconia ceramic ferrules for durable mating performance and are manufactured by established suppliers to ensure consistent quality and up to 1500 mating cycles. Each cable is factory-tested with interferometer and OTDR measurements, and ships with test results for input loss and return loss.

Key specifications

How to use

Connect the SN/UPC end to the corresponding SN-style transceiver or adapter and the LC/UPC end to the LC port on a patch panel or optical device, ensuring correct duplex orientation for transmit and receive channels. Route the cable following standard cable management practices to avoid sharp bends (observe minimum bend radius) and mechanical strain. Verify link performance after installation using appropriate test equipment and compare to the supplied input loss and return loss measurements.

Recommendations

Store and handle the patch cord in a clean environment; avoid contaminating connector endfaces and clean connectors with approved fibre cleaning tools before mating. Use the LSZH jacketed cord where reduced smoke and halogen-free behavior is required. For installations requiring the lowest possible return loss, consider APC polishing where supported by the system.
