D-Link DES-1200M [19/48] Network planning

1000BASE-LX

 In Multi-mode, the fiber optic segment cannot exceed

550m(62.5/125µm), 550m(50/125µm) in length.

 In single mode the fiber optic segment cannot exceed

10km(9/125µm).

Network Planning

Using a switch, such as a 4-Slot Modular Switch, can expand

network topologies and enhance network performance.

Each port on a switch connects to a separate network with its

own collision domain. Separating networks with these switches

allows you to expand 10Base-T networks past the four-hub limit

and expand 100Base-TX networks past the one or two hub

limit.

These switches also filter incoming traffic. On standard hubs

and repeaters, any data received on a port is forwarded to all of

the other ports. On switches, data received on one port is

forwarded only to the port of the destination device, and if the

traffic is local, the data is not forwarded at all. Also, switches

can forward multiple data transaction at once.

To expand your network topology or enhance network

performance, use the Max Switch II as collapsed backbone or

to increase file server performance, to segment large networks,

to interconnect 10Mbps networks with 100Mbps networks, or to

overcome the limitations of 10Base-T and 100Base-TX

networks.
