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:

XR 12000 Series specifications

The Cisco Systems XR 12000 Series routers are designed to meet the demands of modern networking environments, ensuring high performance, scalability, and reliability for service providers and large enterprises. This series is engineered to deliver advanced features that facilitate a range of applications, including core routing, edge services, and data center interconnect.

One of the main features of the XR 12000 Series is its advanced routing capabilities. These routers utilize the Cisco IOS XR software architecture, which provides a modular and distributed operating system. This architecture enhances system reliability as individual processes can be restarted independently without affecting overall system operations. As a result, service providers can achieve higher uptime and enhanced service continuity.

The XR 12000 Series supports a robust set of technologies that enable efficient data handling and transport. Notably, the series includes support for Multiprotocol Label Switching (MPLS), which enhances traffic engineering, distributed bandwidth management, and Quality of Service (QoS) capabilities. This makes the XR 12000 a preferred choice for operators looking to optimize their network performance under increasing traffic loads.

Furthermore, the XR 12000 Series excels in scalability. With a flexible modular design, operators can customize their systems to fit specific needs by adding additional line cards or service modules. These enhancements enable operators to scale both up and down based on fluctuating demands, accommodating numerous high-bandwidth applications such as video streaming, cloud services, and IoT.

Security is another critical characteristic of the XR 12000 routers. Built-in cybersecurity features, including secure boot, strong encryption, and integrity checks, protect against unauthorized access and ensure data integrity. Coupled with advanced monitoring and logging capabilities, these routers can help operators maintain robust security postures.

Additionally, the XR 12000 Series is designed to facilitate seamless integration with existing network infrastructures. The routers support various protocols and interfaces, which ensure interoperability with legacy systems and enhance overall network efficiency. This flexibility allows service providers to future-proof their investments while adapting to evolving technological landscapes.

In summary, the Cisco XR 12000 Series routers stand out for their advanced routing capabilities, scalability, robust security features, and compatibility with modern and legacy network infrastructures. These attributes make them an ideal choice for organizations seeking to enhance their networking capabilities in a rapidly changing digital environment.
