  • Supports 100Gb/s throughput for high-bandwidth links
  • QSFP28 connectors fit standard 28-port switches
  • Passive copper design needs no external power
  • Three-metre reach suits typical rack-to-rack runs
  • Mellanox 1600 series built for EDR InfiniBand clusters

3 m QSFP28 passive copper cable

The Mellanox MCP1600-E003E26 is a 3 metre passive copper cable terminated with QSFP28 connectors. It is built for InfiniBand EDR links operating at up to 100 Gb/s between compatible switches, adapters or storage nodes. The assembly ships new and carries manufacturer part number MCP1600E003E26 with UPC 783555219225.

Suits short-reach rack cabling; not for longer runs

This cable suits installers who need a 3 metre point-to-point link inside a single rack or between adjacent racks where the port density and power budget favour passive copper. Buyers who need longer reach, active signal conditioning or optical media should look at other media types because the passive design limits the usable distance.

Passive construction keeps latency low

Because the cable uses no active electronics, it adds negligible latency and draws no power from the QSFP28 ports. The copper twinax maintains signal integrity across the full 3 metre length at 100 Gb/s, so sustained throughput matches the burst rate without thermal throttling or firmware initialisation delays.

Questions about this item

What QSFP28 ports must my switches or NICs already provide for this 3m Mellanox MCP1600-E003E26 cable to plug in?

Both ends need QSFP28 receptacles rated for up to 100Gb/s InfiniBand EDR; the cable plugs directly into those ports without transceivers.

Will this cable interoperate with legacy QSFP+ gear running at lower speeds in the same rack?

The cable is built for QSFP28 100Gb/s EDR links; mixing it with QSFP+ equipment would require separate compatible cables and matching port types.

How can I confirm the link is running at the intended 100Gb/s EDR rate after installation?

Check the switch or host interface counters for a 100Gb/s InfiniBand EDR connection and verify zero CRC errors on the port statistics.
