The fiber modules feature ST fiber connections and provide “Link” activity LED, “Re-
ceiving” LED and a “Partition” LED.
The coax module features a coax BNC connector and provides “Receiving” and “Parti-
tioned” LED displays. It also provides a switch selectable termination element which
eliminates the need for an external termination resistor when connecting at the end of
a coax line.

Application 5. Single fiber backbone
In this case, two buildings are connected using a 2 km fiber . The LAN in building A
is interconnected via UTP and the LAN in building B is interconnected via coax. The
collision rule is met (5-4-1) with a fiber distance limit at 500 m. A detailed calculation
(not provided here) reveals that the 2 km fiber may be used.
