Fiber Ports - Moxa Technologies EtherDevice Hardware Installation Manual

There are also two types of Ethernet cable in use. The first type is
a straight-through cable, and the second type is a cross-over cable.
The general connection rules are:
A straight-through cable is used to connect dislike ports:
MDI ↔ MDI-X.
A cross-over cable is used to connect like ports:
MDI ↔ MDI or MDI-X ↔ MDI-X.
For example, you should use a straight-through cable to connect
your computer's Ethernet NIC to a HUB or switch, but use a
cross-over cable to connect your computer's Ethernet NIC to
another computer's Ethernet NIC.

Fiber Ports

Moxa EtherDevice Server's fiber switched ports operate at a fixed
100 Mbps speed and full-duplex mode to provide the best
performance. The fiber ports are factory-built as either a
multi-mode or single-mode SC connector. Consequently, you
should use fiber cables that have SC connectors at both ends.
When plugging the connector into the port, make sure the slider
guide is positioned to the right side so that it fits snuggly into the
port.
The 100 Mbps fiber ports are switched ports, and perform as a
domain, providing a high bandwidth backbone connection that
supports long fiber cable distances (up to 2 km for multi-mode, and
15 km for single-mode) for installation versatility.
