1.3 EMC38-12 OVERVIEW
The EMC38-12 converts ethernet IEEE 802.3 10Base-T signals to
ethernet IEEE 802.3j 10Base-FL signals. It also converts ethernet
10Base-T signals to ethernet 10Base-FL signals. The rear panel has a
50-pin Champ connector (RJ-71) that supports twelve twisted pair
segments. The front panel has twelve 10Base-FL multimode ST ports.
Figure 1-1 shows the EMC38-12 ports. The 10Base-FL connectors are
backward compatible with FOIRL connectors.
Each of the rear panel twisted pair ports has a corresponding fiber port.
For example
: Twisted pair Port 1 converts signals to fiber optic Port 1,
twisted pair port 2 converts signals to fiber optic port 2, etc.
