30-metre Mellanox EDR InfiniBand cable

The Lenovo 00MP556 is a 98.40 ft fibre-optic link built for Mellanox EDR InfiniBand clusters. It uses QSFP28 connectors and targets high-performance compute nodes that need low-latency interconnects over long rack runs.

Sustained throughput in cluster workloads

Optical signalling keeps signal integrity stable across the full 30 metre span without the attenuation that limits copper at this length. The cable maintains line-rate EDR bandwidth during extended MPI jobs and storage bursts where copper alternatives would throttle.

Thermals noise and power profile

Passive optical construction adds no active components, so the assembly generates no audible noise and draws negligible power from the switch ports. Heat contribution inside dense racks is effectively zero compared with active optical or copper alternatives.

Questions about this item

Does the 30M Mellanox Edr Ib Optical Qsfp28 Cable generate noticeable heat when run continuously?

The fiber-optic construction carries light instead of electrical current, so the cable itself produces no measurable heat during all-day operation.

What ports must my equipment already have to use the 00MP556 cable?

Both ends require QSFP28 transceivers; your switches, adapters or servers must present QSFP28 sockets that accept the module.

Will the 98.40 ft length work with older InfiniBand hardware that only supports shorter copper runs?

Yes — the optical design removes the distance limit of copper, so the 98.40 ft reach is compatible with legacy equipment that has QSFP28 ports.
