Fibre Channel SFP Transceivers
The iSR6152 router supports SFP optical transceivers for the Fibre Channel ports.
A transceiver converts electrical signals to and from optical laser signals to
transmit and receive data. Duplex fibre optic cables plug into the transceivers,
which then connect to the devices. The Fibre Channel ports are capable of
transmitting at 2Gbps, 4Gbps, or 8Gbps; the transceiver must also be capable of
delivering these rates.
Although the SFP transceivers are hot-pluggable, this interrupts communication
with the connected device. For more information, see “Removing and Replacing
SFP Transceivers” on page 5-1.
