## Summary description

The BlueOptics SFP3131EU7.5MK is a 7.5 m InfiniBand fibre optic cable featuring LC connectors and OM3 fibre type. With a core diameter of 50 µm, it supports full duplex communication, making it ideal for high-speed data transfer in data centers and networking applications.

## Long description

The BlueOptics SFP3131EU7.5MK is a 7.5 m OM3 multimode fibre optic duplex patch cord with LC/UPC connectors in aqua. Designed for 850 nm transmission, this LC–LC cable uses 50/125 µm laser-optimized multimode fiber (LOMMF) to enable full-duplex, high-speed links between patch panels, optical transceivers and active equipment in data centres and enterprise networks. The cable is jacketed in flame-retardant LSZH material for reduced smoke and no halogen release in fire scenarios.
Advantages
This fibre patch cord offers low attenuation (approximately 3.5 dB/km) and high return loss; connector polishing options such as UPC are used to further optimise back reflection. Components are sourced from recognised manufacturers and use zirconia ceramic ferrules that support long connector life and up to 1500 mating cycles. Each cable is tested with interferometer and OTDR and delivered with a measurement protocol for insertion loss and return loss, ensuring reliable, traceable performance.
Suitable for
 Interconnecting optical transceivers in switches, routers and servers
 Patching between LC ports on patch panels and fibre distribution frames
 Short- to mid-range multimode links in data centres and wiring closets
 Applications requiring LSZH jackets for low smoke and halogen-free operation
Key specifications
 Length: 7.5 m
 Fibre type: OM3 multimode (50/125 µm, laser-optimized)
 Connector type: Duplex LC/UPC to LC/UPC
 Operating wavelength: 850 nm
 Attenuation: approx. 3.5 dB/km
 Jacket material: LSZH (low smoke, zero halogen)
 Duplex/full-duplex capable
 Connector ferrule: zirconia ceramic (high mating-cycle durability)
How to use
Inspect both connectors and ports for contamination before connecting; use appropriate dust caps until installation. Route the cable following rack and cable-management best practices, avoiding tight bends and excessive torsion; respect the manufacturer’s minimum bend radius for multimode patch cords. Insert the LC duplex connectors into the corresponding LC ports until they click; ensure correct polarity if required by the link design. For links to optical transceivers, follow the transceiver and switch vendor instructions for hot-plugging and handling.
Usage recommendations
Store and install the cable in controlled environments and avoid sharp bends or crushing. Use labelled patching and maintain the supplied test protocol for link documentation and troubleshooting. For environments with longer reach requirements, verify that OM3 multimode performance meets the link budget and consider single-mode alternatives if necessary.
