When installed into a MIL-S1000 switch, this Module
provides 4 x 100Mbps Fast Ethernet fiber ports which can
be used to:
# Connect the Switch to the backbone of your network;
that is, to a basement switch, hub or router.
# Connector the Switch to a 100Mbps server or end
station.
An ST, SC, MT-RJ or VF-45 connector provides the link to
the multi-mode fiber cabling and three LEDs show five
status of the Module at-a glance. A DIP-switch sets the
operating mode to half duplex or full duplex (default).
