A Hot Standby option is available for those links not otherwise protected
With little effort, the same SDR Series™ radio can be configured to provide traditional Hot Standby protection, as shown to the left. This is for those special situations where loop redundancy is neither available nor required. Since all SDR Series™ Radios use the same ODUs, regardless of configuration, should your requirement change, the radios can easily be reconfigured for Loop Redundancy. We use a special coupler at the rear of the antenna to combine the two ODUs required for Hot Standby operation.
