How to Connect to SFP Fiber Optic Ports

1. Attach the other end to an available port on the switch. Make sure each twisted
pair cable does not exceed 100 meters (328 ft) in length.
2. As each connection is made, the Link LED (on the switch) corresponding to
each port will turn on green to indicate that the connection is valid.
How to Connect to SFP Fiber Optic Ports
The switch provides four slots for SFP-compliant fiber-optic transceivers.
Note that all 1000BASE fiber optic ports operate at 1 Gbps full duplex. All 100BASE
fiber optic ports operate at 100 Mbps full duplex.
Note:
The length of fiber optic cable for a single switched link should not exceed
the relevant standards specified in this section. However, power budget constraints
should also be considered when calculating the maximum fiber optic cable length
for a particular link.
Note:
Maximum distances may vary for different SFP vendors.
