NPE-G2 Memory Information and Specifications

Gigabit Ethernet SFP Connection Equipment

The small for-factor pluggable (SFP) port is a 1000-Mbps optical interface in the form of an LC-type duplex port that supports

IEEE 802.3z interfaces compliant with the 1000BASEX standard. (See Figure 6-10.)

Note The SFP module you ordered is shipped installed in the NPE-G2. Cisco sells individual SFP modules separately and you can change the type of Gigabit Ethernet interface supported by this network processing engine by simply changing its SFP module.

Warning Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures. Statement 70

Figure 6-9shows the Class 1 warning label that appears on the Gigabit Ethernet optical ports.

Figure 6-10shows the duplex LC-type connectors on your multimode or single-mode optical fiber cables. For simplex connectors, two cables are required, one cable for transmit (TX) and a second cable for receive (RX). For duplex connectors, only one cable that has both TX and RX connectors is required. You can use either simplex or duplex connectors to the SFP ports on the NPE-G2.
