The PBN RRAS-O series Analog Return Receiver module with FBC functions for the AIMA3000 access platform is designed for multi-services operators to increase network-return capacities for the ever-growing demand for bandwidth and to efficiently monitor the performance of multiple RF return path signals.

The embedded Full Band Capture (FBC) functionality enables the operator to capture and monitor the return path spectrum, helping to quickly locate upstream noise artifacts and analyse related upstream signal levels.

Advanced spectrum analysis software is available as a standalone tool or a module within PBN’s wider netWatch software suite. The spectrum analysis software toolset also support options for simple integration into operators existing network OSS or BSS.

Online management and control capabilities can be centrally monitored and controlled through a PBN netWatch server networked to one of the Ethernet ports of the ASMM module.

  • Bandwidth 5 ~ 204 MHz to meet DOCSIS 3.1 frequency band requirements
  • RF output 40 dBmV at -6 dBm optical input and OMI of 6%
  • Wide band receiver (1260 ~ 1620nm) to suit CWDM and DWDM applications
  • Allows up to 128 receivers (8x16 modules) in only 4 RU of space
  • User-selectable MGC or AGC
  • Easy to install due to RF-Paddle board backplane design
  • Intergrated Optical Passive Module DMUX with express port for increased headend optical shelf density
  • Full Band Capture offers automated and 24/7 return path/upstream RF and data performance monitoring and analysis
  • Dedicated test port per return channel
  • Real-time alarm monitoring
  • Help operators preemptively identify and address spectrum variances
  • Lower capital expenses by eliminating the need for expensive test equipment
  • Web-browser access eliminates the need for a thick client and a mobile APP is available
  • Improve network maintenance efficiency and Increase customer satisfaction
  • FBC software which can work independently, in PBN NMSE or be integrated into third-party systems
  • Individual eletric control attenuator and equalizer for each reciever
