Cisco 7200 VXR Installation and Configuration Guide
OL-5013-08
Chapter 3 Installing a Cisco 7200 VXR Router
Connecting I/O Controller, NPE-G1, or NPE-G2 Cables
The mode-conditioning patch cord assembly is composed of duplex optical fibers, including a
single-mode-to-multimode offset launch fiber connected to the transmitter, and a second conventional
graded-index multimode optical fiber connected to the receiver. The use of a plug-to-plug patch cord
maximizes the power budget of multimode 1000BASELX and 1000BASELH links.
Note
The mode-conditioning patch cord is required to comply with IEEE standards. The IEEE found that link
distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light
from the laser at a precise offset from the center, which is accomplished by using the mode-conditioning
patch cord. At the output of the patch cord, the
SFP-GE-L=
is compliant with the IEEE 802.3z standard
for 1000BASELX.
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.
Gigabit Ethernet GBIC Connections
The Gigabit Interface Converter (GBIC) port is a 1000-Mbps optical interface in the form of an SC-type
duplex port that supports IEEE 802.3z interfaces compliant with the 1000BASEX standard. (See
Figure 3-18
.)
Note
The GBIC is a separately orderable part and does not ship installed in your I/O controller. You must
install the GBIC before you connect the cables to it.
Figure 3-18
shows the simplex and duplex SC-type connectors on your multimode or single-mode
fiber-optic cables. For simplex connectors, two cables are required, one cable for transmit (TX) and a
second cable for receive (RX). For duplex connectors, one cable that has both TX and RX connectors is
required. You can use either simplex or duplex connectors for the C7200-I/O-GE+E or the NPE-G1.
