## Long description

The BlueOptics 25GB-4-C03-QSFP28 3 m InfiniBand fibre optic cable is a multimode assembly with a QSFP28 plug on one end and four SFP28 plugs on the other, intended for high-throughput server and switch interconnections.

How to use
Inspect both device ports and the cable connectors for damage or debris before installation. Insert the QSFP28 end into the device with the corresponding port and then connect each SFP28 plug to its intended SFP28 port until the connectors latch. Route the cable to avoid sharp bends and excessive tension, keeping bend radii within manufacturer guidelines for multimode fibre. For removal, depress the latch on each connector and withdraw straight out to avoid stress on the fibre and ports.
Usage recommendations
Use this cable for short-distance, high-speed interconnects inside racks and between adjacent racks. Maintain proper fibre handling practices: avoid kinks, keep connector endfaces clean using approved cleaning tools, and secure cables to prevent movement that could stress connectors. Verify device compatibility with QSFP28 and SFP28 interfaces and ensure both ends support the intended 25 Gbit/s operation mode.
