Ethernet and Optical SFP Modules
The IR1101 Ethernet and Optical SFP modules provide connections to other devices. These field-replaceable
transceiver modules provide the uplink interfaces. The Ethernet and Optical modules can be either copper or
optical. Details are in the two tables listed below.
The Local connectors (LCs) provide the fiber-optic connection. RJ-45 connectors allow copper connections.
You can use any combination of the supported SFP modules listed in the table that follows.
Note: The IR1101 is designed to operate in the Industrial temperature range (-40C to +85C internal component
temperature range) and therefore cannot support commercial rated SFPs.
