Cisco XFP, OC-192/STM-64, Short-Reach/Intra-Office Optics Module 10000Mbit/s 1310nm network media converter

XFP, OC-192/STM-64, Short-Reach/Intra-Office Optics Module, 1310 nm, SMF, LC Transmitter
In the transmit direction, the transceiver module receives a 10-Gbps electrical data signal and transmits the data as an optical signal via an E/O 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.
