Remote Connections With Fiber Cable; Making Vlan Connections - AMX NXA-ENET8-2POE Operation/Reference Manual

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 10 km, a 1000BASE-LH link up to
80 km, and a 100BASE-FX (SMF) link up to 20 km. This allows the switches to serve as a collapsed
backbone, providing direct connectivity for a widespread LAN.

Making VLAN Connections

The NXA-ENET8-2POE 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 can 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.
