How to Connect to SFP Fiber Optic Ports
The switch provides two slots for SFP-compliant fiber-optic transceivers.
Note that all 1000BASE fiber optic ports operate at 1 Gbps full duplex. The 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.
