BlueOptics SC282701L5M26 InfiniBand fibre optic cable 5 m QSFP28 4xSFP28 Black

The BlueOptics SC282701L5M26 InfiniBand fibre optic cable is a 5 m direct-attach assembly that links a QSFP28 interface to four SFP28 ports. Intended for high-density network environments, this black cable supports high-speed data transmission and low latency connections between switches, servers and host adapters. Its compact design and factory-terminated connectors simplify installation in rack and blade systems while maintaining signal integrity for short-range links.

Advantages

This InfiniBand fibre optic cable provides multi-lane connectivity through a single QSFP28 end and four SFP28 ends, enabling aggregation of four 25 Gbps lanes for 100 Gbps equivalent throughput. The cable design reduces the need for additional transceivers, lowers insertion loss, and helps maintain consistent performance in dense cabling environments. Its 5 m length balances reach and manageability in typical data centre topologies.

How to use

Install the cable by inserting the QSFP28 end into the corresponding QSFP28 port on a switch or network adapter and connect the four SFP28 ends to the target SFP28 ports on the paired device. Ensure ports are powered down or follow hot-plug procedures recommended by your equipment vendor. Route the cable to avoid excessive bend radius and mechanical stress; keep it separate from power cables when possible to minimise interference and maintain airflow within racks.

Recommendations

For optimal performance, use this 5 m cable for short-range links within the same rack or adjacent racks. Verify compatibility with QSFP28 and SFP28 ports on your hardware and follow manufacturer guidelines for hot-plugging. Avoid tight bends and protect connector ends from dust when not in use; periodic inspection of connectors and secure seating will help sustain reliable links.
