Description

XFP Module
– The XFP transceiver module 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.
– 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 converter. The optical output power is held constant by an automatic power control circuit. The transmitter also contains a Clock Data Recovery (CDR) 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 CDR circuit.
