XFP Module Connections
The 10GLR, 10GER, and 10GZR XFP modules include an optical transmitter and receiver pair
integrated with Clock and Data Recovery (CDR) integrated circuits. The XFP modules provide
high-speed serial links at the rate of 10.3125 Gbps (10-Gigabit Ethernet LAN PHY mode) and
9.95328 Gbps (10-Gigabit Ethernet WAN PHY mode) on single-mode fibers (SMF). 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 laser, enabling data transmission over SMF through an LC connector.
The receive side recovers and retimes the 10-Gbps optical data stream from a photo detector
transimpedance amplifier and passes it to an output driver.
See the label on the XFP module for the technology type and model. Figure 2-64 shows an XFP module
and Table 2-53 shows the XFP module specifications.
