CAUTION: When 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 to lasers. To protect your eyes against
radiation harm, never stare into an open fiber-optic port.
Step 1: Insert the SFP optical module into its corresponding slot.
Step 2: Locate the Rx and Tx ports of the SIC-1FEF 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
SIC-1FEF panel. ON means an Rx link is present and OFF means the opposite. In
the latter case, check the line status.
SIC-8AS
Introduction SIC-8AS, the 8-port asynchronous serial interface card, is mainly used to transceive
and process the asynchronous data streams.
SIC-8AS has these features:
■ Each asynchronous serial port provides a rate up to 115.2 Kbps.
■ Supports the terminal access service and asynchronous dedicated line.
■ Serves as the small-/medium-sized ISP dial-up access server when an
asynchronous serial port is used for dial-up.
