About the Product

The PBN AIMA3000 RRAR series Analog Return Receiver - Redundant (RRAR) are designed for multi-services operators to increase network-return capacities for the ever-growing demand for data and voice bandwidth, while minimizing physical headend space and power requirements.

The RRAR, is designed to plug into PBN’s latest generation Advanced Intelligent Multi- Service Headend Platform (AIMA3000). The RRAR incorporates four independent optical return-path receivers that can operate at any wavelength between 1260~1620 nm. This density allows up to 64 independent receivers in only 4 RU of space. The user can set each receiver individually for operation in either manual gain control (MGC) mode or automatic gain control (AGC) mode based on optical input power. The unit has a low-noise profile and highperformance amplifiers to ensure a good signal-to-noise ratio as well as low distortion characteristics. The RRAR is compatible with PBN’s existing optical nodes including the ODN1P, ODN2P, ODN4P, and ODN2000. With high RF outputs, the RRAR can be adapted to work with various headend configurations.

The RRAR can also be conveniently monitored and controlled through a computer connected to one of the Ethernet ports via the ASMM module.

All module settings are retained in non-volatile memory to ensure trouble-free operation. Bulk updating, automatic uploading and downloading of configuration files is possible using PBN’s NMSE web-based management system.
