3 Gigabit Ethernet SFP module
Step 1 Remove the plug from the SFP so that you can insert the cables. Keep the plug for use should you ever disconnect the
optical fiber cables.
Because invisible laser radiation may be emitted from the aperture of the port when no fiber cable is connected,
Warning
avoid exposure to laser radiation and do not stare into open apertures.
Step 2 Attach the appropriate optical fiber cable directly to the SFP. You can use either simplex or duplex connectors for most
devices.
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.
