## Summary description

The BlueOptics SFP3131EU50MK is a 50 m long OM3 fibre optic cable with LC connectors. It features a core diameter of 50 µm and supports full duplex communication, making it ideal for high-speed data transfer in InfiniBand applications.

## Long description

The BlueOptics SFP3131EU50MK InfiniBand fibre optic cable is a 50 m OM3 (G50/125 µm) duplex patch cord with LC/UPC connectors in aqua. Designed for 850 nm multimode transmission, this laser-optimized multi-mode fiber (LOMMF) cable supports full-duplex InfiniBand links and high-speed data transfer between patch panels, transceivers and active equipment. The cable is fitted with a flame-retardant LSZH jacket for reduced smoke and no halogen release in the event of fire.
Advantages
This OM3 fibre cable offers low attenuation (approximately 3.5 dB/km) and low insertion loss combined with high return loss; connector end-face polishing can be selected to further optimise return loss. BlueOptics uses branded fibre from established manufacturers and precision connectors with zirconia ceramic ferrules to ensure reliable, low-loss connections and long connector life. Each cable is factory-tested with interferometer and OTDR and delivered with a measurement protocol of insertion and return loss values, meeting Telcordia GR-326-Core 4.4 and common IEC/EN standards.
Suitable for
 InfiniBand high-speed interconnects and cluster networking
 Server and storage connectivity using LC duplex transceivers
 Data centre patching between panels and active equipment
 Short- to medium-reach multimode links at 850 nm
Key specifications
 Fibre type: OM3, laser-optimized multimode (G50/125 µm)
 Length: 50 m
 Connectors: Duplex LC/UPC to LC/UPC
 Wavelength: 850 nm transmission optimized
 Attenuation: approx. 3.5 dB/km
 Jacket material: LSZH (low smoke, zero halogen)
 Colour: Aqua
 Connector ferrule: zirconia ceramic, rated for up to 1500 mating cycles
 Factory testing: interferometer and OTDR with measurement protocol included
How to use
Connect the duplex LC connectors to matching LC ports on transceivers, patch panels or switches, observing correct transmit/receive orientation for full-duplex operation. Avoid tight bends and secure the cable with suitable routing and strain relief to maintain minimum bend radius and prevent mechanical stress on connectors. For installations requiring specific return loss performance select the appropriate connector polish type and verify measured values on the supplied test report.
Usage recommendations
Store and handle the cable in a clean environment and avoid contaminating connector end faces; clean connector end faces with approved fibre cleaning tools before mating. Use the LSZH jacketed cable in indoor and data centre environments where low smoke and halogen-free behaviour is required. For customised lengths or specific connector polishes, consult technical support to ensure compatibility with existing transceivers and system requirements.
