Choosing the Correct
Cables for the
100BASE-X SFP Ports
The 100BASE-LX10 SFP transceiver supports a direct connection to a
single-mode fiber-optic cable. The 100BASE-FX SFP transceiver supports a
direct connection to multi-mode fiber-optic cable. Table 20 describes the
port cable range for each connection:
