## Summary description

The BlueOptics SFP3133FU3MK is a 3 m InfiniBand fibre optic cable featuring LC and ST connectors. It utilizes OM4 fibre with a core diameter of 50 µm, ensuring full duplex communication. Ideal for high-speed data transmission in networking applications.

## Long description

The BlueOptics SFP3133FU3MK is a 3 m InfiniBand fibre optic patch cable with duplex LC/UPC to ST/PC connectors, manufactured using laser-optimized multimode OM4 fiber (50/125 µm core/cladding). Designed for full-duplex data transmission at 850 nm, this 3 metre LC–ST OM4 cable provides low attenuation and high return loss for reliable short- to medium-range connections in networking environments. The cable features a magenta, flame-retardant LSZH jacket and is compatible with patch panels, optical transceivers and InfiniBand interfaces.
Advantages
The OM4 multimode fiber offers improved bandwidth and lower attenuation compared with lower OM classes, supporting high-speed data transfer and optimized performance at 850 nm. Factory-assembled connectors with zirconia ceramic ferrules ensure consistent endface quality and long mating life. The LSZH jacket reduces smoke and avoids halogen release in the event of fire, meeting common industrial safety standards. Each cable is tested with interferometry and OTDR; a measurement protocol for insertion loss and return loss is included with delivery.
Suitable for
 Connections between InfiniBand devices and switches
 Patch panel to transceiver or transceiver-to-transceiver links
 High-speed data centres and server rack interconnects
 Short- to medium-range multimode fiber links requiring OM4 performance
Key specifications
 Fiber type: OM4 multimode (50/125 µm)
 Connector type: duplex LC/UPC to ST/PC
 Length: 3 m
 Wavelength: optimized for 850 nm
 Attenuation: approx. 2.5 dB/km (typical)
 Jacket: LSZH (flame-retardant, low smoke, halogen-free)
 Polish options: UPC standard (with APC available for return-loss optimization)
 Duplex/full-duplex support
How to use
Inspect both connector endfaces and mating ports for contamination or damage before insertion. Align the LC and ST connectors with the corresponding ports and insert until a positive click or secure seating is achieved; avoid excessive bending of the fiber and maintain the minimum bend radius specified by the installer. For patching in racks, route the cable through cable management trays to prevent stress on connectors. When deploying transceivers, ensure port compatibility and clean endfaces with appropriate fiber cleaning tools to minimize insertion loss.
Usage recommendations
Store and handle the cable in controlled conditions to prevent contamination and mechanical damage. Use LC dust caps when connectors are not in use and follow vendor guidelines for minimum bend radius and maximum tensile load. For critical links, verify insertion loss and return loss on-site after installation using appropriate test equipment; retain the provided test protocol for asset records.
