Overview of the Ethernet network and
the FMBT-21 module
Contents of this chapter
This chapter contains a short description of the Ethernet network and the topology
supported by the FMBT-21 adapter module.
Ethernet network
Ethernet standards support a variety of physical media (coaxial cable, twisted pair,
fiber optics) and topologies (bus and star).
The FMBT-21 module supports twisted pair as the physical media in a star topology.
The maximum length for an Ethernet segment on twisted pair media is 100 meters.
All twisted pair media between the Ethernet node and the switch or router must be
shorter than 100 meters, including media within patch panels.
