Remote Connections with Fiber Cable
Fiber optic technology allows for longer cabling than any other media type.
A 1000BASE-SX MMF Gigabit link can connect to a site up to 550m
away, a 1000BASE-LX (SMF) link up to 10 km, and a 1000BASE-ZX link
up to 70 km. This allows end-users at two sites to use the same Internet
connection, share server resources, and communicate with each other.
In the figure below, a 1000BASE-SX port on the switch in Building 1 is
providing 1000 Mbps connectivity to the switch in Building 2.

Making VLAN Connections
This switch supports VLANs which can be used to organize any group of
network nodes into separate broadcast domains. VLANs confine
broadcast traffic to the originating group, and can eliminate broadcast
storms in large networks. This provides a more secure and cleaner network
environment.
VLANs can be based on untagged port groups, or traffic can be explicitly
tagged to identify the VLAN group to which it belongs. Untagged VLANs
