Remote Connections with Fiber Cable
Fiber optic technology allows for longer cabling than any other media type.
A 10GBASE-SR (MMF) link can connect to a site up to 300 meters away,
and a 10GBASE-LR (SMF) link can connect to a remote site up to 10 km
away. This allows a 10 Gigabit Ethernet Switch to serve as a collapsed
backbone, providing direct connectivity for a widespread LAN.
A 10GBASE-SR XFP transceiver can be used for a high-speed connection
between floors in the same building, and a 10GBASE-LR XFP can be used
for high-bandwidth core connections between buildings in a campus
setting or to connect to a remote site.
The figure below illustrates this switch connecting multiple segments with
fiber cable.
