Milan Technology MIL-S1000 - Manual (Page 23)

1000BASE-SX and LX Network Guideline
1000BASE-SX
# In multi-mode, the fiber optic segment cannot exceed
220m(62.5/125 µm) or 500m(50/125µm) in length.
1000BASE-LX
# In multi-mode, the fiber optic segment cannot exceed
550m(62.5/125 µm), 550m(50/125µm) in length.
# In single-mode the fiber optic segment cannot exceed
10km(9/125 µm).
Network Planning
Using a switch, such as a MIL-S1000, 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.
