Network Adapter Card Installation Guide

Dual port adapters also simplify the task of relocating nodes in a network.
When a node is moved to a new location that also involves a change to the
media connection, such as from twisted pair cable to fiber optic cable, no
change to the adapter is necessary since the adapter has ports for both
types of medium.
Selecting which port to use on a dual port adapter is usually dictated by
the distance of the node from the Ethernet switch of hub or the working
environment. The maximum operating distance for the twisted pair port is
100 meters, typically making this port appropriate for nodes within that
operating distance from the Ethernet switch or hub.
The fiber optic port is appropriate for nodes that are greater than 100
meters from the switch or hub or in working environments where
electromagnetic emissions from manufacturing or other heavy equipment
could affect network transmissions over twisted pair cabling.
All of the adapters described in this guide use the same network adapter
card drivers. This further simplifies the task of network maintenance by
reducing the number of drivers you need to maintain.
