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
