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.

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 1-25shows the faceplate for the Gigabit Ethernet line card.
