4.17.3 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), enabling data transmission over SMF through an LC connector. The receive
side recovers and retimes the 10 Gbps optical data stream from a PIN photo detector, transimpedance
amplifier and passes it to an output driver.
The XFP module uses the bail clasp latching mechanism as shown unlatched in Figure 4-21 and latched
in Figure 4-22. See the label on the XFP for technology type and model.
XFP dimensions are:
• Height 0.33 in. (8.5 mm)
• Width 0.72 in. (18.3 mm)
• Depth 3.1 in. (78 mm)
