Mellanox MCP1600-C001E30N Passive Copper Cable ETH 100GbE QSFP28 1m Black

SKU CH-9N7P-9HQ3X

A 1 metre passive copper cable carrying 100 GbE over QSFP28 connectors

  • 100 GbE throughput for high-speed links
  • QSFP28 connectors fit standard 100G ports
  • Passive copper design needs no external power
  • 1 metre length suits rack-to-rack runs
  • 30 AWG conductors keep the cable flexible

100GbE QSFP28 passive copper cable

The Mellanox MCP1600-C001E30N is a one-metre passive copper cable built for 100GbE Ethernet links. It uses a QSFP28 connector on each end and a 30AWG conductor. The assembly suits data-centre racks and high-performance compute clusters that need a short, fixed-length interconnect.

Thermals noise and power draw

Passive copper construction means the cable draws no power and produces no audible noise. Heat generated by the transceivers at each end is dissipated through the connector housing without any active cooling. The 30AWG conductors keep resistive loss low across the one-metre span.

Sustained load behaviour

Signal integrity is maintained for continuous 100GbE throughput because the cable is factory-characterised for the full 100Gb/s rate. No active equalisation or retimer is present, so performance depends on the host ports meeting the same electrical specification. The fixed one-metre length prevents excess insertion loss that longer passive reaches would introduce.

Questions about this item

How do I install the MCP1600-C001E30N passive copper cable and what step is often missed?

Align the QSFP28 connector with the port, insert until the latch clicks, then verify the link LED shows 100GbE; the step often missed is not seating the latch fully, which leaves the link at a lower speed.

What maintenance or replacement will the MCP1600-C001E30N cable need over time?

The passive copper cable has no active parts to service; inspect the QSFP28 ends and 30AWG jacket periodically for dust or kinks, and replace the cable if the connector latch breaks or the link drops from 100GbE.

What limit appears first on the MCP1600-C001E30N during sustained 100GbE use?

The 1 metre length and 30AWG gauge set the reach limit; signal integrity degrades before thermal issues arise, so the cable must stay at or under 1 metre for reliable 100GbE operation.
