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 (RJ21) that supports 12 twisted pair segments. The
front panel has twelve 10BASE-FL type single mode ST ports that are
backward compatible with FOIRL type connectors. Figure 1-1 shows the
EMC39-12 ports.
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.
