Cisco ONS 15454 Installation and Operations Guide, R3.2
March 2002
Chapter 9 Ethernet Operation
E Series Cards
9.1.7 G1000-4 Gigabit Interface Converters
Gigabit interface converters (GBICs) are hot-swappable input/output devices that plug into a Gigabit
Ethernet card to link the port with the fiber-optic network. Figure 9-6 shows a GBIC. The type of GBIC
determines the maximum distance that the Ethernet traffic will travel from the card to the next network
device.
The G1000-4 card supports three types of standard Cisco GBICs; SX, LX and ZX. Support for the
copper-media CX GBIC will be added in a future release.
1000BaseSX operates on multi-mode fiber optic link spans of up to 550 m in length. 1000BaseLX
operates on single-mode fiber optic links of up to 10 km in length. 1000BaseZX operates on single-mode
fiber optic link spans of up to 70 km in length, and link spans of up to 100 km are possible using premium
single mode fiber or dispersion shifted single mode fiber.
Figure 9-6 A gigabit interface converter
Table 9-1 shows the available GBICs for the G1000-4 card.
Caution Use only GBICs certified for use in the ONS 15454 G1000-4 card (Cisco product numbers
15454-GBIC-SX and 15454-GBIC-LX).
For GBIC installation and cabling instructions, see the “Fiber-Optic Cable Installation” section on
page 1-52.
9.2 E Series Cards
The E series cards incorporate layer 2 switching, while the G series card is a straight mapper card. The
ONS 15454 E series cards include the E100T-12/E100T-G and E1000-2/E1000-2-G. E series cards
support VLAN, IEEE 802.1Q, spanning tree, and IEEE 802.1D. An ONS 15454 holds a maximum of ten
Ethernet cards, and you can insert Ethernet cards in any multipurpose slot. For card specifications, see
the Card Reference chapter in the Cisco ONS 15454 Troubleshooting and Maintenance Guide.
