Cisco ONS 15454 SDH Troubleshooting and Maintenance Guide, R3.3
May 2002
Chapter 3 Card Reference
E1000-2-G Card
3.27 E1000-2-G Card
The E1000-2-G card provides two ports of IEEE-compliant, 1000 MBits/s (Mbps) interfaces. Each
interface supports full-duplex operation for a maximum bandwidth of 2 GBits/s (Gbps) per port and 4
GBits/s (Gbps) per card. Each port auto-configures for full duplex and 802.3x flow control. The
E1000-2-G card uses GBIC modular receptacles for the optical interfaces.
Two GBIC modules are offered as separate orderable products for maximum customer flexibility: 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. The 1300 nm LX optics are
designed for single-mode fiber and distances of up to five kilometers. Other GBIC modules for long
reach 1550 nm and twisted-pair copper will be offered for use with the E1000 card in a future release.
Figure 3-45 shows the card faceplate and Figure 3-46 shows a block diagram of the card.
