Cabling and Specifications

Note Use only the SFP modules supplied by Cisco with your Gigabit Ethernet line card. Each SFP module contains an internal serial EEPROM that is security-programmed by the SFP manufacturer with information that provides a way for Cisco (through the Cisco IOS software) to identify and validate the SFP module as a module type that was tested and qualified by Cisco to operate properly with Cisco Gigabit Ethernet line cards. Unapproved SFP modules (those not purchased directly from Cisco) will not work on the Gigabit Ethernet line card.

10-Gigabit Ethernet

The 1-Port 10-Gigabit Ethernet line card uses single-mode fiber-optic cable. The maximum distance for single-mode installations is determined by the amount of light loss in the fiber path. If your environment requires the light to travel close to the typical maximum distance (as listed in Table 16), you should use an optical time domain reflectometer (OTDR) to measure the power loss.

The Ethernet line card is offered in two transceiver options:

•Long haul or long wavelength, 1310 nanometers (nm) nominal, used for 1000BASE-LR links.

•Long haul or long wavelength, 1550 nm nominal, used for 1000BASE-ER links.

Table 15 describes the operating parameters for the transceiver options.

Fiber-Optic Interface Cables

Depending on the line card (refer to Table 4 on page 4), use a single-mode or multimode fiber-optic interface cable with LC-type or SC-type connectors to connect an Ethernet interface on the Ethernet line card in your Cisco XR 12000 Series Router to another Ethernet interface, router, or switch.

Note Fiber optic cables are not available from Cisco Systems. They can be purchased from cable vendors.

The following types of cables are used with Ethernet line cards to connect your router to another router or switch:
