GBIC Port Connections
Step 1
Remove the plug from the GBIC module so that you can insert the cables. Keep the plug for use should
you ever disconnect the optical fiber cables.
Warning
Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is
connected, avoid exposure to laser radiation and do not stare into open apertures.
Step 2
Attach the appropriate optical fiber cable directly to the GBIC module. You can use either simplex or
duplex connectors for most devices. (
Figure 4-10
shows a GBIC module installed in Gigabit Ethernet
slot 0.)
•
For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for
receive (RX).
•
For duplex connectors, only one cable that has both TX and RX connectors is required.
