Use only the SFP and SFP+ modules supplied by Cisco Systems, Inc. with your Ethernet line card. Each
module contains an internal serial EEPROM that is security-programmed by the module manufacturer with
information that provides a way for the Cisco IOS XR software to identify and validate the module as qualified
to operate properly with Cisco Ethernet line cards. Unapproved SFP or SFP+ modules (those not purchased
directly from Cisco Systems, Inc.) do not work on Ethernet line cards. To verify the version of the installed
module, see Verifying the Transceiver Modules , on page 144.
Caution
10-Gigabit Ethernet XFP Modules
The 8-Port 10-Gigabit Ethernet (GE) 2:1 oversubscribed line card, 4-Port 10GE line card, and 8-Port 10GE
80 Gbps line rate card use single-mode fiber-optic cables. The maximum distance for single-mode installations
is determined by the amount of light loss in the fiber path. If your environment requires the light to travel
close to the typical maximum distance, you should use an OTDR to measure the power loss.
Fiber-Optic Interface Cables
Depending on the line card (see Ethernet Line Card and MPA Comparison), use a single-mode or multimode
fiber-optic interface cable with LC-type connectors to connect an Ethernet interface on the line card in your
Cisco ASR 9000 Series Router to another Ethernet interface, router, or switch.
Fiber optic cables are not available from Cisco Systems. They can be purchased from cable vendors.
Note
The following types of cables are used with line cards to connect your router to another router or switch:
• Single-mode—Generally yellow in color.
• Multimode—Generally gray or orange in color. Multimode cables are multifiber cables that carry 12
channels of fiber data.
• Lucent connector (LC)—See figure below Simplex LC Cable Connectorand Duplex LC Cable Connector.
You can use two cables with simplex connectors, or one cable with dual, keyed connectors.
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams or
view directly with optical instruments. Statement 1051
