E1000-2 Card
4.33 E1000-2 Card
Do not use the E1000-2 when the XC10G cross-connect card is in use. The ONS 15454 uses E1000-2
cards for Gigabit Ethernet (1000 Mbps). The E1000-2 card provides two IEEE-compliant, 1000 Mbps
ports for high-capacity customer LAN interconnections. Each port supports full-duplex operation.
Figure 4-36 shows the card faceplate and a block diagram of the card.
The E1000-2 card uses standard Cisco gigabit interface converter (GBIC) modular receptacles for the
optical ports. GBICs are hot-swappable input/output devices that plug into a Gigabit Ethernet port to link
the port to the fiber-optic network. Cisco provides two GBIC models: one for short-reach applications
and one for long-reach applications. The short-reach model connects to multimode fiber and the
long-reach model requires single-mode fiber.
For Software R2.2.0 and later, both GBIC modules are offered as separate orderable products: an IEEE
1000Base-SX compliant, 850 nm optical module and an IEEE 1000Base-LX-compliant, 1300 nm optical
module, the 850 nm SX optics are designed for multimode fiber and distances of up to 220 meters on
62.5 micron fiber and up to 550 meters on 50 micron fiber. For more information see the Cisco ONS
15454 Installation and Operations Guide.
