1000BASE-SX Ethernet interface card

The 1000BASE-SX Ethernet interface card implements short-wavelength

(850 nm) laser transmissions. Use this interface card to connect to fiber Gigabit Ethernet interfaces on other devices in your network, as well as to provide increased throughput. The 1000BASE-SX Ethernet interface card has a single type LC fiber connector.

Figure 35 shows the 1000BASE-SX Ethernet interface card.

The port on the 1000BASE-SX Ethernet interface card accommodates a multimode fiber (MMF) cable that meets MMF standards. Select fiber cable for this interface as follows:

•50-micron MMF cable: provides a distance range of 500–550 meters (m)

•62.5-micron MMF cable: provides a distance range of 220–275 m

You can order a 10-foot MMF cable from Nortel:

•Order no. DM0011117 provides an LC-to-LC connector

•Order no. DM0011118 provides an LC-to-SC connector
