BlueOptics SFP5141FU3MKB InfiniBand fibre optic cable 3 m MPO 4x LC

BlueOptics SFP5141FU3MKB is a 3 meter InfiniBand/MPO breakout fiber cable with a single MPO/UPC connector to four LC/UPC duplex connectors. The cable uses OM4 multimode fiber (50/125 µm), contains 8 fibers wired for QSFP usage (pins 1–4 & 9–12), and features a flame-retardant LSZH (Low Smoke Zero Halogen) jacket. It is intended for short-range high-speed links in data centers, storage area networks and local network environments where MPO-to-LC fanout is required.

Advantages

The BlueOptics SFP5141FU3MKB offers low insertion loss and high return loss, factory-tested with interferometer and OTDR with a measurement protocol included. Connectors use high-quality zirconia ceramic ferrules and branded components to ensure durability up to the specified mating cycles. The LSZH sheath minimizes smoke and avoids halogen release in case of fire, and the compact MPO-to-4xLC design eliminates the need for splicing or special assembly tools, simplifying and accelerating installation.

Key specifications

How to use

Connect the MPO end to an MPO port or MPO cassette and plug the four LC duplex connectors into corresponding LC ports or transceivers. Ensure correct pin alignment for QSFP lane mapping (pins 1–4 and 9–12). No splicing or special tools are required; verify connections visually and consult the supplied measurement protocol for insertion loss and return loss values after installation.

Recommendations

Use the cable for short-range, high-speed multimode links within data centers or network rooms. Store and handle the MPO connector and LC ferrules carefully to avoid contamination; clean connectors before mating and avoid tight bends beyond the fiber manufacturer’s minimum bend radius.
