Step 1: Insert the SFP optical module into its corresponding slot.
Step 2: Locate the Rx and Tx ports of the GEF interface. Connect them to another
device with two optical fibers: Rx to Tx and Tx to Rx.

Step 3: Power on the router and check the behavior of the LINK LED on the card
panel. ON means an Rx link is present and OFF means the opposite. In the latter
case, check the line status.

Introduction
FIC-2SAE/FIC-4SAE/FIC-8SAE, 2-/4-/8-port enhanced high-speed
synchronous/asynchronous serial interface card, transmits, receives, and processes
data on the synchronous/asynchronous serial interface. They support both
synchronous and asynchronous modes. In the former case, they support the
DTE/DCE mode.
