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.
