## Summary description

The BlueOptics SFP5141FU5MKB is a 5 m OM4 fibre optic cable featuring MPO and 4x LC connectors. It supports full duplex communication with a core diameter of 50 µm, making it ideal for high-speed data transfer in InfiniBand applications.

## Long description

The BlueOptics SFP5141FU5MKB InfiniBand fibre optic cable is a 5 m OM4 multimode breakout cable with an MPO connector on one end and four LC duplex connectors on the other. Designed for 50 µm core multimode transmission at 850 nm, this cable supports full duplex communication across four optical lanes and is intended for high-speed data transfer in InfiniBand and related network environments. The cable features an LSZH (Low Smoke Zero Halogen) jacket, 8 fiber cores (pinout 1–4 & 9–12 for QSFP usage) and is factory-tested for insertion loss and return loss to ensure consistent signal quality.
Advantages
The MPO to 4x LC breakout design reduces installation time by eliminating the need for field splicing and simplifies connectivity between MPO cassettes, QSFP modules and LC interfaces. Use of OM4 multimode fibre provides improved bandwidth and lower attenuation for short- to medium-distance high-speed links. The LSZH sheath minimizes smoke and hazardous gas emission in case of fire, meeting common industry safety standards. Factory testing with interferometry and OTDR and the inclusion of a measurement report ensure traceable optical performance.
Suitable for
 InfiniBand high-speed links and fabric interconnects
 Data center fibre trunking and MPO cassette connections
 Storage area networks (SAN) and server-to-switch links
 Patch panels and QSFP-to-LC breakout deployments
Key specifications
 Length: 5 metres
 Fiber type: Multimode OM4 (50/125 µm)

 Connector B: 4 × LC duplex (LC/UPC)
 Wavelength optimized: 850 nm
 Jacket: LSZH (Low Smoke Zero Halogen), flame-retardant
 Tested for insertion loss and return loss; measurement report included
 Designed for QSFP/MPO lane applications and full-duplex operation
How to use
Route the BlueOptics MPO to 4x LC cable between the MPO-equipped device or cassette and the destination equipment with LC ports, taking care to maintain bend radius and avoid sharp kinks. Connect the MPO end to the MPO cassette or QSFP breakout port following the correct pinout, then plug each LC duplex connector into the corresponding LC receptacles on switches, transceivers or patch panels. No field splicing or polishing is required; verify connectivity and optical performance using the supplied measurement report or site test equipment if needed.
Usage recommendations
Maintain the manufacturer's recommended minimum bend radius, keep connectors clean using appropriate cleaning tools before mating, and secure the cable to avoid strain on connectors. Use the included test report to confirm link budgets during installation and follow data center cable management practices to preserve signal integrity and simplify future changes.
