AC6223 Ingress blocker
The AC6223 is a plug-in ingress blocker module (PB f > 16 MHz) designed to be used in AC-series distribution amplifiers. It filters out the lowest frequency band of the upstream channel.
This plug-in module is designed to be used in AC-series distribution amplifiers. It filters out the lowest frequency band of the upstream channel. Lower ingress level guarantees the safe operation of the EMS transmission and prevents the overloading of the return path laser transmitter. This module is planned to be placed at the input of the upstream signal path instead of the input attenuator pad.
