Chapter 2 Overview: Cisco 7600 Series Ethernet Services Plus Line Cards
Cisco 76-ES+XC-20G3C, 76-ES+XC-20G3CXL Line Card Overview
The XFP modules provide high-speed serial links at the following rates: 9.95 Gbps (OC-192) and
10.3125 Gbps (10 Gigabit Ethernet) on single-mode fiber (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 technology type and model.
XFP module dimensions are:
• Height: 12.5 mm
• Width: 18.35 mm
• Length: 71.1mm
The XFP module temperature range is 0°C to 70°C. Figure 2-41 shows a typical XFP module.

Connectors and Cabling
The XFP optical transceiver module on the Cisco 76-ES+XC-20G3C, 76-ES+XC-20G3CXL line card
require dual LC/PC connectors. Only connections with patch cords with PC or UPC connectors are
supported. Patch cords with APC connectors are not supported. All cables and cable assemblies used
must be compliant with the standards specified below:
• GR-20-CORE: Generic Requirements for Optical Fiber and Optical Fiber Cable
• GR-326-CORE: Generic Requirements for Singlemode Optical Connectors and Jumper Assemblies
• GR-1435-CORE: Generic Requirements for Multi-Fiber Optical Connectors
Figure 2-42 shows the cable type for use with the XFP optical transceiver module on the Cisco
76-ES+XC-20G3C, 76-ES+XC-20G3CXL line card.
