100 Gbps EDR QSFP28 cable

This Mellanox MCP1600-E001E30 is a 1 metre passive twinax cable with QSFP28 connectors on both ends. It carries 100 Gbps EDR InfiniBand or Ethernet traffic and draws power from the 3.3 volt port supply. The 26 AWG conductors meet a BER of 1E-13 to 1E-15 when used with Mellanox equipment.

Who this suits

The cable suits data-centre racks linking switches, adapters or storage nodes that accept QSFP28 ports at EDR rates. It is not for buyers who need longer reach than one metre, who require active optical cables, or who must connect SFP28 or legacy QSFP+ ports.

Installation notes

Push each QSFP28 end straight into the cage until the latch clicks; the 33 mm minimum bend radius means tight routing behind dense patch panels needs care. The PVC OFNR jacket is stiff when cold, so allow it to warm before sharp bends. A common issue is inserting the connector upside down, which damages the latch and prevents link-up.

Questions about this item

Which ports must my equipment already have to use this QSFP28-to-QSFP28 cable?

Both ends require a QSFP28 port that supports 100 Gbps EDR InfiniBand or Ethernet.

Will the 1 m length and 26 AWG twinax work with older QSFP+ gear running at lower speeds?

The cable is built for 100 Gbps EDR; older QSFP+ ports may not recognise the module or may fall back to unsupported rates.

How can I verify the link is operating at the rated 100 Gbps after installation?

Check the switch or HCA management interface for a 100 Gbps EDR link state and a bit error rate in the 1E-13 to 1E-15 range.
