Figure 2.7.1: A P80F connects combinations of 10 Mbps and100Mbps network devices and
provides a Fast Ethernet fiber backbone for access to the central LAN.
Where there is existing 10 Mbps hubs or switches users, they can easily be cascaded
into any port of the P80F. This allows a simple plug-and-play addition of 100Mbps ports to an
existing 10 Mbps network without having to change it. Nodes that are capable of 100Mbps
speed can be moved to a P80F port, and will automatically operate at the higher speed.
The 100Mb fiber port on the P80F can be used for accommodating high performance
data transfers, and provides fiber connectivity built-in rather than needing an auxiliary media
converter unit. The 100Mbps traffic does not use the bandwidth of the 10 Mbps domain, so
overall performance of the network is sustained at the highest possible level.
Example 2. Magnum P80C
The Magnum P80C fits very well in a small business experiencing a need to scale its
LAN quickly and cost effectively. With its Half / Full duplex switching capability, the P80C
provides a very economical high bandwidth solution at each copper port. The Dual-Speed
functions support a mixed environment of 10 Mbps and 100Mbps users, and the switching full /
half duplex capability on all eight ports provides bandwidth for high performance. The up-link
on Port 1 enables easy expansion.
