The 1-port Gigabit Ethernet half-height line card:
•
Contains one Gigabit Ethernet port that provides a trunk uplink to switches and core routers
•
Provides the Cisco 10000 series with an IEEE 802.3z-compliant Ethernet interface that can run up to 1 Gbps in full duplex mode.
Note
Bandwidth can reach a theoretical maximum of 711 Mbps due to backplane limitations of the PRE-1 (Part Number ESR-PRE1). The backplane bandwidth is not a limitation when using the PRE-2 (Part Number ESR-PRE2) or future PREs.
You install this line card in a Cisco 10000 chassis half-height slot carrier, which you must first install in the Cisco 10000 chassis slot. You can run this line card with a second line card in the other subslot.
The line card uses a small form-factor pluggable (SFP) module that supports a variety of Gigabit Ethernet interface types (SX, LX/LH, ZX, BASET, and CWDM), which you can change or upgrade at any time.
For more information about Coarse Wave Division Multiplexer (CWDM) Small Form-Factor Pluggable (SFP) laser optical transceiver modules, see the Cisco CWDM GBIC and CWDM SFP Installation Note at:
http://www.cisco.com/univercd/cc/td/doc/product/gbic_sfp/gbic_doc/78_15222.htm
Note
Only SFP modules purchased from Cisco work with the Gigabit Ethernet line card software.
Note
For the longwave 1470 nm laser SFP module (CWDM-SFP-1470=), use a long reach single-mode cable or an attenuator with a short reach cable.

Cables and Connectors
The 1-port Gigabit Ethernet half-height line card supports single Ethernet interfaces based on SFP technology. The following SFP modules are supported by this line card:
•
1000BASE-SX SFP—The SFP-GE-S=, 1000BASE-SX SFP module operates on ordinary multimode fiber-optic link spans of up to 550 meters in length.
•
1000BASE-LX/LH SFP—The SFP-GE-L=, 1000BASE-LX/LH SFP module operates on ordinary single-mode fiber-optic link spans of up to 10,000 meters in length.
•
1000BASE-ZX SFP—The GLC-ZX-SM=, 1000BASE-ZX SFP module operates on ordinary single mode fiber-optic link spans of up to 70 kilometers in length. Link spans of up to 100 km are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. The SFP module provides an optical link budget of 23 dB—the precise link span length depends on multiple factors such as fiber quality, number of splices, and connectors.
•
1000BASE-T SFP—The SFP-GE-T (1000BASE-T copper SFP module) provides full-duplex Gigabit Ethernet connectivity to high-end workstations and between wiring closets over an existing copper network infrastructure. The SFP-GE-T maximum cabling distance is 328 feet (100 m).
The Coarse Wave Division Multiplexer (CWDM) Small Form-Factor Pluggables (SFPs) are hot-swappable, laser optical transceiver modules. You can plug these SFPs into standard receptacles in Cisco routers and switches to convert Gigabit Ethernet electrical signals into a single-mode fiber-optic (SMF) interface. The router supports the following CWDM SFPs:
•
CWDM-SFP-1470 SFP—Longwave 1470 nm laser, single mode
•
CWDM-SFP-1490 SFP—Longwave 1490 nm laser, single mode
•
CWDM-SFP-1510 SFP—Longwave 1510 nm laser, single mode
•
CWDM-SFP-1530 SFP—Longwave 1530 nm laser, single mode
•
CWDM-SFP-1550 SFP—Longwave 1550 nm laser, single mode
•
CWDM-SFP-1570 SFP—Longwave 1570 nm laser, single mode
•
CWDM-SFP-1590 SFP—Longwave 1590 nm laser, single mode
•
CWDM-SFP-1610 SFP—Longwave 1610 nm laser, single mode
You can connect the CWDM SFPs to CWDM passive optical system optical add/drop multiplexer (OADM) or multiplexer/demultiplexer plug-in modules using single-mode fiber-optic cables with standard LC connectors. For more information, see the Cisco CWDM GBIC and CWDM SFP Installation Note at the following URL:
http://www.cisco.com/univercd/cc/td/doc/product/gbic_sfp/gbic_doc/78_15222.htm
When shorter distances of single-mode fiber are used, it may be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. A 5-decibel (dB) or 10-dB inline optical attenuator should be inserted between the fiber-optic cable plant and the receiving port on the GLC-ZX-SM= at each end of the link whenever the fiber-optic cable span is less than 25 km. CWDM SFPs require a minimum of 12-dB optical attenuation. If the fiber itself is not providing the attenuation, then an attenuator device is required.
Note
The required line card SFP module is shipped installed in the line card. Cisco sells individual SFP modules separately and you can change the type of Gigabit Ethernet interface supported by this line card by changing its SFP module.
Use these guidelines for installing SFP 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 SFP modules. Always read the label on the SFP module to determine the technology type and model.
•
You can install and remove SFP modules with power on to the system.
•
Disconnect all cables before removing or installing an SFP module. We strongly recommend that you do not install or remove the SFP module with optical fiber cables attached to it.
•
SFP modules are keyed to prevent incorrect insertion.

1 A mode-conditioning patch cord is required. Using an ordinary patch cord with MMF, 1000BASE-LX/LH SFP modules, and a short link distance (tens s of meters) can cause transceiver saturation resulting in an elevated bit error rate (BER). In addition, when using the LX/LH SFP module with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord between the SFP module 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).

Mode-Conditioning Gigabit Ethernet Patch Cord Description
A mode-conditioning patch cord can be used with the SFP-GE-L= (SFP module) to allow reliable laser transmission between the single-mode laser source on the SFP 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 10-4) to a graded-index multimode optical fiber. Figure 10-4 shows a diagram of the mode-conditioning patch cord assembly.

The mode-conditioning patch cord assembly is composed of duplex optical fibers, including a single-mode-to-multimode offset launch fiber connected to the transmitter, and a second conventional graded-index multimode optical fiber connected to the receiver. The use of a plug-to-plug patch cord maximizes the power budget of multimode 1000BASE-LX and 1000BASE-LH links.
The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center, which is accomplished by using the mode-conditioning patch cord. At the output of the patch cord, the SFP-GE-L= is compliant with the IEEE 802.3z standard for 1000BASE-LX.
