Chapter 3 Installing a Cisco 7200 VXR Router
Connecting I/O Controller, NPE-G1, or NPE-G2 Cables
Gigabit Ethernet SFP Module Connections
The 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 3-16.)
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 3-15 shows the Class 1 warning label that appears on the Gigabit Ethernet optical ports.
Figure 3-15 Laser Class 1 Warning Label
Figure 3-16 shows 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 module ports on the NPE-G2.
Note We strongly recommend cleaning optical fiber connections before attaching cables to equipment. See the
“Fiber-Optic Cleaning Information” section on page 5-10 for information.
