Figure 13 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 ports on the
Cisco 7201 router.
Install the SFP Module Optical Fiber Cables
The SFP module ports support IEEE 802.3z (optical Gigabit Ethernet) interfaces compliant with 1000BASESX and
1000BASELX specifications.
SFP modules ordered with the Cisco 7201 router come installed in the system. Optical fiber cables are commercially available;
they are not available from Cisco.
Figure 12 Optical SFP Modules and Copper SFP Modules
The optical SFP modules can occupy any of the four optical Gigabit Ethernet ports, 0/0 through 0/3. However, the copper SFP
modules can occupy only optical Gigabit Ethernet ports 0/2 and 0/3.
