100Gbps QSFP28 Active Optical Cable 30m

This Mellanox MFA1A00-E030 is a 30 metre active optical cable built for 100Gbps InfiniBand EDR links. It targets data-centre operators and HPC integrators who need reliable long-reach connectivity between switches, servers or storage arrays. The QSFP28 connectors plug directly into standard ports without extra transceivers. Buyers who need copper DAC economics or runs beyond 30 metres should consider other media.

Practical limits of the InfiniBand EDR interface

The cable supports the full 100Gbps line rate defined by the InfiniBand EDR specification. VCSEL transmitters keep signal integrity over the 30m length while the OFNP jacket meets plenum fire ratings. A 7.5mm minimum bend radius restricts tight routing inside dense racks. The assembly is not rated for outdoor or direct-burial deployment.

Capacity and headroom for 100Gbps links

At 100Gbps the link handles typical EDR cluster traffic, storage replication and MPI workloads with ample margin. The ≈50 million hour MTBF suggests multi-year continuous operation in temperature-controlled rooms. Beyond 30 metres the same cable family does not extend, so longer runs require different optics or repeaters. The fixed 30m length also prevents field shortening or length adjustment.

Questions about this item

Should I pick the 30m length or a shorter QSFP28 cable for my InfiniBand EDR link?

The 30m cable supports the full 100Gbps rate across the entire length; choose a shorter run only if your rack-to-rack distance is less than 30m to reduce slack.

What real-world throughput does the 100Gbps rating deliver inside a server?

In an InfiniBand EDR fabric the cable carries 100Gbps end-to-end, so applications see the full line rate minus only protocol overhead.

How does the QSFP28 interface limit the cable's performance in practice?

The QSFP28 connector is specified for 100Gbps InfiniBand EDR, so the interface itself does not cap the cable below its rated speed.
