Chapter 4 Flexible Interface Cards (Router 6000)

4.4.5 Connecting the Interface Optic Fiber

Caution:

In connecting the optical fiber, observe the following:

Do not over-bend the optical fiber. Its curvature radius must be no less than 10 cm (3.9 in).

Ensure that the Tx and Rx ends are correctly connected. Ensure that the fiber ends are clean.

Warning:

Laser danger: Invisible laser radiation may be emitted from the fiber-optic ports which are connected with lasers. To protect your eyes against radiation harm, never stare into an open fiber-optic port.

Step 1: Insert the SFP module into its corresponding slot.

Step 2: Locate the Rx and Tx ports of the GE 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 status 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.
