1.3 EMC39-12 OVERVIEW
The EMC39-12 converts Ethernet IEEE 802.3 10BASE-T signals to
Ethernet IEEE 802.3j 10BASE-FL signals. The rear panel has a 50-pin
Champ connector (RJ71) that supports twelve twisted pair segments. The
front panel has twelve 10BASE-FL single mode ST ports. Figure 1-1
shows the EMC39-12 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.
