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 2-65 shows an XFP module

and Table 2-54 shows the XFP module specifications.

XFP module dimensions are:

• Height: 12.5 mm

• Width: 18.35 mm

• Length: 71.1mm
