Remote Connections with Fiber Cable

Fiber optic technology allows for longer cabling than any other media type. A

1000BASE-SX (MMF) link can connect to a site up to 550 meters away, a

1000BASE-LX (SMF) link up to 5 km, and a 1000BASE-LH link up to 70 km. This

allows a switch stack to serve as a collapsed backbone, providing direct connectivity

for a widespread LAN.

A 1000BASE-SX SFP transceiver can be used for a high-speed connection between

floors in the same building and a 10GBASE-LR module can be used for

high-bandwidth core connections between buildings in a campus setting. For

long-haul connections, a 1000BASE-LH SFP transceiver can be used to reach

another site up to 70 kilometers away.

The figure below illustrates three Gigabit Ethernet switch stacks interconnecting

multiple segments with fiber cable.
