Cisco has a Nexus 9000 model which supports FC. But all ports are QSFP, how can we connect FC to QSFP?

Model: Cisco Nexus 9336C-FX2-E Switch

Port: 36 x 40/100-Gbps QSFP28 ports

Descriptions: The Cisco Nexus 9336C-FX2-E Switch (Figure 2) is a 1RU switch that supports 7.2 Tbps of bandwidth and over 2.4 bpps. The switch can be configured to work as 1/10/25/40/50/100-Gbps or as 16-, 32-Gbps Fibre Channel ports[2] offering flexible options in a compact form factor. Breakout is supported on all ports.

You'll need breakouts for the QSFP28 ports - either QSFP28 to 4x SFP28 or QSFP+ to 4x SFP+ for DACs, or a QSFP28/+ short-wave transceiver on that end with a four-pair fiber fanout (MPO to 4x LC) and the appropriate single-lane FC transceivers on the other end.

  • Does breakout work for FC ? I cannot find any breakout specially for FC connectors. would you please guide me? May 10, 2021 at 7:16
  • The exact parts should be in the documentation. Since the breakout is on the Nexus 9000 side, the FC side doesn't see anything from it.
