10GBASE Fiber Connections
The switch’s 10GBASE modules provide a cost-effective way to build a
10 Gbps Ethernet network. A 10GBASE-SR (MMF) link can connect to a
device up to 300 meters away, a 10GBASE-LR (SMF) link up to 10 km, and a
10GBASE-ER (SMF) link up to 40 km. This allows network managers to
scale their Ethernet networks from 10, 100, or 1000 Mbps to 10 Gbps.
A 10GBASE-SR XFP transceiver can be used for a high-speed connection
between floors in the same building and a 10GBASE-LR XFP transceiver
can be used for core connections between buildings in a campus setting. And
for long-haul connections, a 10GBASE-ER XFP transceiver can be used to
reach another site up to 40 km away.
The figure below illustrates a connection between two sites and to their
remote switches.
