Using Fiber with Ethernet
To use fiber with Ethernet switches, you need to use a switch with either built-in ports that
support a particular optical Ethernet standard, or a switch with modular ports that allow you
to change the Ethernet standard used on the port. Refer back to Figure 2-8, which shows a
photo of a switch with two SFP+ ports, into which you could insert any of the supported
SFP+ modules. Those SFP+ ports support a variety of 10-Gbps standards like those listed in
Table 2-4.
