Step 1 Check to be sure that either the SFP optical port or the RJ-45 port is used on ports 0/0 and 0/1. Only one
of the pair can be chosen.
Step 2 Remove the plug from the SFP module so that you can insert the cables. Keep the plug for use should
you ever disconnect the optical fiber cables.
Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into
beams or view directly with optical instruments.
Statement 1051
Step 3 Attach the appropriate optical fiber cable directly to the SFP module. You can use either simplex or
duplex connectors for most devices. (Figure 2-16 shows an SFP module with a duplex connector being
installed in SFP port 0/1.)
• 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.
