4.20.3 XFP Description
The 10-Gbps 1310-nm and 1550-nm XFP transceivers are integrated fiber optic transceivers that provide
high-speed serial links at the following signaling rates: 9.95 Gbps, 10.31 Gbps, and 10.51 Gbps. The
XFP integrates the receiver and transmit path. The transmit side recovers and retimes the 10-Gbps serial
data and passes it to a laser driver. The laser driver biases and modulates a 1310-nm or 1550-nm
distributed feedback (DFB) laser, enabling data transmission over single-mode fiber (SMF) through an
LC connector. The receive side recovers and retimes the 10-Gbps optical data stream from a
positive-intrinsic-negative (PIN) photodetector, transimpedance amplifier and passes it to an output
driver.
The XFP module uses the bail clasp latching mechanism, shown unlatched in Figure 4-26 and latched in
Figure 4-27. See the label on the XFP for technology type and model.
