Chapter 4 Configuring the Gigabit Ethernet Ports Figure 4-1 GBIC Module Installing, Removing, and Maintaining GBICs 11825 Receiver Transmitter Table 4-1 lists the GBIC modules that are supported by the Catalyst 2948G and 2980G switches. Table 4-1 Supported GBIC modules GBIC Type Model Number Fiber-optic 1000BASE-SX WS-G5484= Fiber-optic 1000BASE-LX/LH WS-G5486= Fiber-optic 1000BASE-ZX WS-G5487= Copper 1000BASE-TX GBIC WS-G5483= Coarse Wave Division Multiplexing (CWDM) fiber-optic 1000BASE-X GBIC CWDM-GBIC-1470= CWDM-GBIC-1490= CWDM-GBIC-1510= CWDM-GBIC-1530= CWDM-GBIC-1550= CWDM-GBIC-1570= CWDM-GBIC-1590= CWDM-GBIC-1610= Note Cisco 1000BASE-LX/LH interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 10 kilometers over single-mode fiber (SMF) versus the 5 kilometers specified in the standard. Other GBIC media types may be supported as additional technology becomes available. 78-6286-05 Catalyst 2984G, 2948G-GE-TX, and 2980G Switch Hardware Installation Guide 4-3
