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-ZX link up to 100 km. This
allows a switch 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. For long-haul connections, a 1000BASE-ZX SFP
transceiver can be used to reach another site up to 100 kilometers away.
The figure below illustrates three TigerSwitch 10/100/1000 units interconnecting
multiple segments with fiber cable.

Making VLAN Connections
This switch supports VLANs which can be used to organize any group of network
nodes into separate broadcast do m ains. VLANs confine broadcast traffic to the
originating group, and can eliminate broadcast storms in large networks. This
provides a more secure and cleaner networ k 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 ca n be used for small
networks attached to a single switch. However, tagged VLANs should be used for
larger networks, and all the VLANs assigned to the inter-switch links.
