XFP Description and Specifications

The 10 Gbps 1310 nm XFP transceiver is an integrated fiber optic transceiver that provides a high-speed

serial link at the following signaling rates: 9.95 Gbps, 10.31 Gbps, 10.51 Gbps, and

10.66/10.71/11.10 Gbps which apply to 10GBASE-LR (fibre channel and Ethernet) as well as

OC-192/STM-64 SONET/SDH. 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 DFB (distributed feed-back) laser, 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 8 and latched in

Figure 9. 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)

XFP temperature ranges are:

• COM—commercial operating temperature range -5 C to 70 C

• EXT—extended operating temperature range -5 C to 85 C

• IND—industrial operating temperature range -40 C to 85 C

Caution Do not add labels or markings to the XFPs.
