It immediatly retransmits the data
It signals to the other nodes that it is about to retransmit the data, and then does so
It waits for a random of time before checking the network for activity and then retransmits the data
It signals to the network that the its data were damaged in a collision, waits a brief period of time before checking the network for activity, and then retransmits the data
The SFP will be capable of higher throughputs
The SFP can be added or removed without affecting operations, thus allowing for customization and future upgrades
The SFP can accept multiple types of connectors, allowing the router to connect to dispirate network types
The SFP promises greater security, as it can encrypt and decrypt data
