4.14.4 Interface Optical Fiber

Like the FICCPOS, the ROUTER 1-PORT OC3 POS FIC uses optical fibers with
LC-type connectors (see Error! Reference source not found.).

4.14.5 Connecting the Interface Optical Fiber

Step 1: Insert the SFP card into its corresponding slot.
Step 2: Locate the Rx and Tx fiber-optic interfaces on the interface card. Use two
fibers to connect the ROUTER 1-PORT OC3 POS FIC to another device: Rx to Tx and
Tx to Rx.
Step 3: Power on the device and check the LINK LED on the ROUTER 1-PORT OC3
POS FIC panel: ON means the Rx link is present and OFF means the opposite. In the
latter case, check the line status.
Warning:
Because invisible laser radiation may be emitted from the aperture of an optical port when no fiber is
connected or the dust cap is removed, do not stare into the open aperture.
Replace the dust cap when no fiber is connected to the optical port.
OFF means no link is present; ON means a link is present.
OFF means no data is being transmitted or received; blinking means data is being
received or/and transmitted.
