Alcatel-Lucent 9500 Microwave Packet Radio MPT-3DB20547BBAA02

The Alcatel-Lucent 9500 Microwave Packet Radio, model MPT-3DB20547BBAA02, is a high-capacity outdoor unit (ODU) designed for split-mount microwave backhaul applications. This packet-optimized radio delivers carrier-class Ethernet and TDM services over licensed microwave frequencies, making it a versatile solution for mobile network backhaul, enterprise trunking, and disaster recovery.

Packet and TDM Convergence

The 9500 MPR supports both packet-switched and circuit-switched traffic, enabling a smooth migration from legacy SDH/PDH networks to all-IP transport. It incorporates advanced encapsulation techniques such as GFP, MPLS-TP, and Ethernet over SONET/SDH, ensuring efficient utilization of the microwave spectrum. The unit can handle up to 2 Gbps aggregate throughput, depending on modulation and channel bandwidth.

Split-Mount Architecture

The MPT-3DB20547BBAA02 is an outdoor unit that mounts directly on the antenna or mast, connected via an IF cable to the indoor unit (IDU). This split-mount design reduces feeder losses and simplifies installation. The ODU includes a transceiver with integrated duplexer, low-noise amplifier (LNA), and high-power amplifier (HPA), supporting frequency bands from 6 to 38 GHz.

Modulation and Adaptive Coding

Employing QPSK up to 4096-QAM modulation, the radio dynamically adapts to varying propagation conditions using adaptive modulation and coding (AMC). This ensures maximum throughput during clear weather and maintains link availability during rain fade or obstructions. The unit also supports hitless automatic transmit power control (ATPC) for optimizing signal quality.

Ethernet and Service Features

The 9500 MPR provides native Ethernet ports with VLAN tagging, QoS classification, and traffic shaping. It supports synchronous Ethernet and IEEE 1588v2 for precise frequency and phase synchronization, essential for LTE-TDD and small cell backhaul. The unit also includes OAM features like CFM, Y.1731, and performance monitoring for service-level agreements.

Environmental and Mechanical Robustness

Housed in a weatherproof enclosure (IP67), the ODU operates in temperatures from -33°C to +55°C and withstands high winds, ice, and solar radiation. It features a rugged die-cast aluminium chassis with integrated heatsink and optional heater for cold climates. The unit weighs approximately 15 kg and is easy to handle during pole or rooftop installations.

Management and Security

Integrated management via SNMP, CLI, and web interface allows remote configuration and fault monitoring. The radio supports AES-256 encryption for secure data transmission, as well as RADIUS authentication for management access. The unit also logs events and alarms, facilitating proactive maintenance and rapid fault localization.

Deployment Scenarios

Common deployments include mobile backhaul between cell sites and aggregation nodes, enterprise private networks, and temporary event connectivity. The 9500 MPR can also be used for redundant links in critical infrastructure, such as utilities and public safety networks.

Conclusion

The Alcatel-Lucent 9500 Microwave Packet Radio MPT-3DB20547BBAA02 is a future-ready microwave solution that combines packet efficiency with TDM reliability. Its high capacity, adaptive modulation, and robust construction make it a preferred choice for operators building next-generation transport networks.
