XFP Module
The XFP transceiver module (Figure 5) is a bidirectional device with a transmitter and receiver in the same physical
package. The XFP module contains a 30-pin surface mount connector on the electrical interface and a duplex LC
connector on the optical interface.

Figure 6 shows an XFP transceiver module functional block diagram. It contains a transmitter and receiver.
●
Transmitter: In the transmit direction, the transceiver module receives a 10-Gbps electrical data signal and
transmits the data as an optical signal through an electrical to optical (E/O) converter. The optical output
power is held constant by an automatic power control circuit. The transmitter also contains a clock data
recovery circuit. The function of this circuit is to attenuate and reshape any jitter received on the electrical
interface.
●
Receiver: In the receive direction, the transceiver module receives a 10-Gbps optical signal and converts it to
an electrical equivalent. The receiver contains a clock data recovery circuit.
