Conveged Network Adaptor

Many of you using this type of network card, I am trying to understand how that works, hope someone will explain.
As I understand  that one card/switch support FoC,10GBe and 1GBE ,etc in once card.
My question is it going though one cable Or this card has to have mutiple ports, one for FC/FCoE, and another for 1GB ?
if i want these two network do i have to have a CNA card with two ports to connect two cable? that is one cable for FocE and another for 1GB.
i will appreciate if you put me a link/explanation.

All traffic goes over the same wire, although often the CNA is dual-port so that you can connect to two different switches for failover/multipath capabilities.

Here's a Cisco doc that discusses it:  http://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5000/sw/fcoe/b_Cisco_Nexus_5000_Series_NX-OS_Fibre_Channel_over_Ethernet_Configuration_Guide_/Cisco_Nexus_5000_Series_NX-OS_Fibre_Channel_over_Ethernet_Configuration_Guide__chapter3.html#concept_55AC900539DA4E359CE0C97C3197A0C9

It means that FCoE and 1GB goes out/in through single port, if that port goes down then we are in trouble that the reason some card has two port ,am I correct?
