It can be difficult to choose the proper SFP (Small Form-Factor Pluggable) transceivers for your Cisco ASR 1000 Series routers.
Consumers frequently inquire about compatibility and performance, for example, whether a certain SFP module is supported by their network switch or whether a particular transceiver will operate with their ASR 1001 router.
This page answers frequently asked questions and offers a detailed inventory of SFP transceivers that work with ASR 1000 Series routers.
Common Questions concerning SFP Modules from Users
A lot of consumers run into problems while choosing SFP modules for their networking equipment. These are a few typical queries:
Suitable for use with the ASR 1001 router:
Question: “I want to install fiber modules in the interface slots of the Cisco ASR 1001 router that we recently bought. Which fiber modules are compatible, please? Does one need a specific ASR series of SFPs, or are standard SFPs adequate?”
Problem with the GLC-TE Module and ASR 1002:
Question: “I have a GLC-TE Copper Base-T Module, however I’m having problems with my ASR 1002 router. There is no port appearing. How can I fix this?”
SFP transceivers that are suggested for ASR 1000 Series routers
The SFP-GE-T is the recommended SFP module for Cisco ASR 1000 Series Routers. In order to support a variety of Gigabit Interface Converters (GBICs) and Gigabit Ethernet SFP transceiver modules, Cisco has modified its platforms and software requirements.
The supported transceivers are listed in detail below, along with the minimum software release needed for each.
