Network Uplink Cards
Cisco Half-Height Gigabit Ethernet Line Card
The Cisco HHGE line card (Figure 1-25) contains a single Gigabit Ethernet port that provides a trunk
uplink to switches and core routers. The Cisco HHGE line card provides an IEEE 802.3z compliant
Ethernet interface that can run up to 1 Gbps in full duplex mode. The line card uses a Small Form-factor
Pluggable (SFP) Gigabit interface converter (GBIC) module that supports a variety of Gigabit Ethernet
interface types (SX
LX/LH, and ZX), which you can change or upgrade at any time.
Note Only SFP GBIC modules purchased from Cisco work with the Gigabit Ethernet line card software.
Figure 1-25 shows the faceplate for the Gigabit Ethernet line card.

Warning
Because invisible radiation may be emitted from the aperture of the port when no fiber cable is
connected, avoid exposure to radiation and do not stare into open apertures.

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 a 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 singe-mode fiber.
