Chapter 3 Overview: Cisco 7600 Series Router Shared Port Adapters Figure 3-46 XFP Illustration 1-Port 10-Gigabit Ethernet SPA Overview 129499 Note The 1-Port 10-Gigabit Ethernet SPA only accepts the XFP modules listed as supported in this document. An XFP check is run every time an XFP module is inserted into the 1-Port 10-Gigabit Ethernet SPA and only XFP modules that pass this check are usable by the 1-Port 10-Gigabit Ethernet SPA. The information in this document pertains only to XFP modules that plug into the 1-Port 10-Gigabit Ethernet SPA ports. XFP Port Cabling Specifications Table 3-26 provides XFP port cabling specifications.

Minimum cabling distance for optical XFP module is 2 meters, according to the IEEE 802.3ae standard. 2. Requires 5 dB 1550 nm fixed loss attenuator for < 20 km. Attenuator is available as a spare. The part number is 15216-ATT-LC-5=. You must use a 5 to 10dB of attenuation when connecting a fiber loopback to the XFP optical port. Connection of a direct fiber loopback to the XFP can permanently damage the port's optics. 3. Links longer than 30 km are considered engineered links. XFP Optical Transmit and Receive Specifications Table 3-27 provides XFP optical transmit and receive specifications.
