The 1-port Gigabit Ethernet line card provides:

•A trunk uplink to the core for Gigabit Ethernet aggregation

•The Cisco 10000 system with an IEEE 802.3z-compliant Ethernet interface running at 1 Gbps in full-duplex mode

The Cisco 10000 system supports multiple Gigabit Ethernet line cards to support connectivity to multiple destinations and for redundant and fault-tolerant configurations.

The port uses a Gigabit Interface Converter (GBIC) that supports Gigabit Ethernet rates on a variety of Gigabit Ethernet interface types (SX, LH/LX, ZX) which you can change or upgrade at any time (see Table 11-5).

If you are a registered Cisco.com user, see Feature Navigator for supported features.

Software and Hardware Compatibility

To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether line cards within a system are compatible, but does provide the minimum Cisco IOS requirements for individual hardware line cards, modules, or options.

Cables and Connectors

Table 11-5 lists the 1-port Gigabit Ethernet line card GBIC modules and their respective cable types and lengths.

Use these guidelines for installing GBIC modules:

•There is no correlation of the type of latch to the model (such as SX or LH) or technology type (such as Gigabit Ethernet) of GBIC modules. Always read the label on the GBIC module to determine the technology type and model.

•You can install and remove GBIC modules with power on to the system.

•Disconnect all cables before removing or installing a GBIC module. We strongly recommend that you do not install or remove the GBIC module with optical fiber cables attached to it.

•GBIC modules are keyed to prevent incorrect insertion.

1 Mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required. If you use an ordinary patch cord with MMF, 1000BASE-LX/LH GBICs, and a short link distance (tens of meters), this can cause transceiver saturation, resulting in an elevated bit error rate (BER). In addition, when you use the LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances greater than 984 ft (300 m). 2 100 km over premium single-mode fiber or dispersion shifted single-mode fiber.

Mode-Conditioning Gigabit Ethernet Patch Cord Description

A mode-conditioning patch cord can be used with the WS-G5486 (GBIC module) to allow reliable laser transmission between the single-mode laser source on the GBIC module and a multimode optical fiber cable.

When an unconditioned laser source designed for operation on single-mode optical fiber is directly coupled to a multimode optical fiber cable, an effect known as differential mode delay (DMD) might result in a degradation of the modal bandwidth of the optical fiber cable.

This degradation results in a decrease in the link span (the distance between a transmitter and a receiver) that can be supported reliably. The effect of DMD can be overcome by conditioning the launch characteristics of a laser source. A practical means of performing this conditioning is to use a device called a mode-conditioning patch cord.

A mode-conditioning patch cord is an optical fiber cable assembly that consists of a pair of optical fibers terminated with connector hardware. Specifically, the mode-conditioning patch cord is composed of a single-mode optical fiber permanently coupled off-center (see Offset in Figure 11-4) to a graded-index multimode optical fiber. Figure 11-4 shows a diagram of the mode-conditioning patch cord assembly.
