Note - If using QSFP to QSFP cables to connect the adapter (configured in 4x10Gb mode) to a 40GbE switch, ensure that the QSFP ports on the switch are configured appropriately or support that configuration. Refer to the switch documentation for any special configurations for the QSFP port to work in the 10GbE mode.

Table 1 Connector and Cable Support For the Different Modes

Connector	Optical/Fibre Cable Support		Direct-Attach Copper Cable Support
	Dual 40GbE mode	2x2x10GbE mode	4x10GbE mode
Port 0 (A)	2x40GbE	2x10GbE	4x10GbE
Port 1 (B)	2x40GbE	2x10GbE

Note - In the 2x2x10GbE mode, direct-attach copper cables are not supported.

Note - For the 2x2x10GbE mode, use a Custom 2-way splitter cable which utilizes port C and D of the MPO/MTP connector. For all other modes, standard industry cables are supported.
