Figure 4-3. Making SC Port Connections
4. As a connection is made, check the Activity LED on the
switch's front panel for the corresponding module to be sure
that the connection is valid.
Note: If you use the optional SC-ST Converter, be sure to connect
the converter's Tx (Rx) port to the Rx (Tx) port on the other
device.
The 100BASE-FX fiber optic ports operate only at 100 Mbps, full
duplex. You can run a fiber link up to 1.24 miles (2 kilometers).
However, note that power budget constraints must also be
considered when calculating the maximum cable length for your
specific environment.
The 1000BASE-SX fiber optic ports operate at 1 Gbps full duplex,
with auto-negotiation of flow control. The maximum length for
fiber optic cable operating at Gigabit speed will depend on the
fiber type as listed under "1000 Mbps Gigabit Ethernet Collision
Domain" on page 2-6.
