AIMA3000 - RRAQ - Return Receiver Analogue Quad Module

The PBN AIMA3000 RRAQ series advanced quad return-path receivers are designed for multi-services operators to increase network-return capacities for the ever-growing data and voice bandwidth, while minimising physical headend space and power requirements.

The RRAQ, as a key element of the AIMA3000 platform, is designed to plug into PBN’s next-generation Advanced Intelligent Multi-services Access platform (AIMA3000). The RRAQ incorporates four independent optical return-path receivers that operate at any wavelength between 1260~1620 nm. This density allows up to 64 independent receivers in a 4RU rack space. The user can set each receiver individually for operation in either manual gain control (MGC) mode or automatic gain control (AGC) mode. The unit hosts low-noise and high-performance amplifiers to ensure good signal-to-noise as well as low distortion. The RRAQ is backward-compatible with PBN’s existing optical nodes including the ODN2P, ODN4P etc. With high RF outputs, the RRAQ is flexible for various headend configurations.

Microprocessor-based status monitoring and control requires an ASMM module in slot 0 of the chassis and optional hand-held controller (AHHC). The RRAQ can also be controlled through a netbook or laptop connected to one of the Ethernet ports on the AIMA3000’s ASMM module.  Remote control and monitoring by network operating centres is possible via SNMP and HTTP. All module settings are retained in NV memory to ensure trouble-free operation.
