12.3.1 Connecting Fiber Optic Cables
The FOM-2000-SP Fiber Optics Network Module has 4 connections: RX2, RX1, TX2, and
TX1. R stands for Receive and T stands for Transmit.
• Wire the Fiber Optics Network Module from the TX connection to the RX connection,
and from 1 to 2:
• Connect a cable from TX1 of node 1 to RX2 of node 2, and a cable from RX1 of node
1 to TX2 of node 2.
• Connect a cable from TX1 of node 2 to RX2 of node 3, and a cable from RX1 of node
2 to TX2 of node 3.
