Alcatel‑Lucent 9500‑MPR MPT‑HC 23GHz 1/1P ODU Radio – 3DB20473BA AA04

The Alcatel‑Lucent 9500‑MPR MPT‑HC 23GHz 1/1P ODU is a versatile microwave outdoor unit designed for carrier‑grade backhaul applications. With product code 3DB20473BA AA04, this radio supports both 1+0 (single) and 1+1 (protected) configurations, offering operators flexibility to balance capacity and availability. It operates in the 23 GHz band, delivering high throughput over short to medium distances.

Product Overview

This ODU is part of the 9500 Microwave Packet Radio series, which integrates native packet and TDM transport. The MPT‑HC (High Capacity) variant supports channel bandwidths up to 56 MHz and adaptive modulation from QPSK to 2048 QAM, allowing net data rates up to 1.2 Gbps in 1+0 mode and 1.1 Gbps with 1+1 protection (using two radios for diversity). The 1/1P designation indicates that the unit can be configured for either unprotected (1+0) or protected (1+1) operation, with the protection switchover occurring in less than 50 milliseconds.

The ODU includes a built‑in Ethernet switch for local aggregation and supports VLAN, QoS, and synchronization features (SyncE and IEEE 1588v2). It interfaces with the indoor unit (IDU) via a standard IF cable carrying data, control, and power.

Key Features

• Adaptive modulation for optimal performance under varying propagation conditions.

• Automatic transmit power control (ATPC) to maintain link margin.

• 1+1 protection with seamless switchover for high availability.

• Integrated 4‑port Gigabit Ethernet switch for flexible network connections.

• Advanced timing support for mobile backhaul (SyncE, 1588v2).

• Built‑in performance monitoring and diagnostic tools.

Deployment Scenarios

This ODU is ideal for cell site backhaul in LTE and 5G networks, where it aggregates traffic from multiple eNBs and forwards it to the aggregation router. The 1+1 protection option is particularly valuable for mission‑critical links, where service continuity is paramount. In enterprise networks, it can connect remote branch offices to a central data center over a wireless link, bypassing costly leased lines.

The 23 GHz band provides sufficient spectrum for high‑capacity links while maintaining antenna size small enough for urban tower deployments.

Management and Maintenance

Configuration and monitoring are performed via the IDU's web interface or SNMP. The ODU reports received signal level (RSL), modulation level, and bit error rate (BER) in real time. It also supports loopback testing for commissioning and troubleshooting.

Reliability

With a ruggedized enclosure and extensive thermal management, the ODU withstands extreme weather. MTBF exceeds 170,000 hours. The 1+1 option provides an additional layer of resilience, with automatic failover in case of radio or power failure.

Conclusion

The Alcatel‑Lucent 9500‑MPR MPT‑HC 23GHz 1/1P ODU (3DB20473BA AA04) offers a flexible and high‑capacity solution for modern wireless backhaul, balancing cost, capacity, and availability with its innovative protection options.
