Alcatel‑Lucent 9500‑MPR ODU MPT‑HC V2 3DB20474BAAB04 23GHz 23 GHz Microwave Outdoor Unit – 9558HC MPT‑XP

The Alcatel‑Lucent 9500‑MPR ODU MPT‑HC V2 is a state‑of‑the‑art microwave outdoor unit operating in the 23 GHz frequency band. With the specific product code 3DB20474BAAB04 (also denoted as 9558HC MPT‑XP), this ODU offers multi‑gigabit throughput, advanced cross‑polarization interference cancellation (XPIC), and adaptive modulation to meet the stringent capacity and reliability demands of 4G and 5G mobile backhaul networks.

Product Architecture

This second‑generation (V2) MPT‑HC (High Capacity) ODU builds upon the proven 9500 MPR platform, incorporating enhanced digital signal processing, higher output power, and improved receiver sensitivity. It supports channel bandwidths up to 112 MHz and modulation up to 4096 QAM, enabling net data rates exceeding 2 Gbps per polarization. When XPIC is enabled, the unit can transmit two independent data streams on vertical and horizontal polarizations, effectively doubling capacity over a single frequency channel.

The ODU integrates a high‑performance modem, error correction (LDPC), and a low‑phase‑noise local oscillator. It interfaces with the indoor unit (IDU) via a standard IF cable carrying both power and 10 GbE data. The unit is equipped with a P120 waveguide flange for direct antenna mounting.

Key Features

• Adaptive modulation and coding (ACM) for dynamic link adaptation to rain and fading.

• Hitless automatic transmit power control (ATPC) to maintain optimal link margin.

• Cross‑polarization interference cancellation (XPIC) for dual‑polarization capacity.

• Integrated Ethernet switching with VLAN, QoS, and advanced synchronization (SyncE/1588).

• Built‑in spectrum analysis, loopback, and BER testing for commissioning.

• Remote firmware upgrade and configuration via the IDU.

Deployment Scenarios

This ODU is ideal for high‑capacity short‑ to medium‑haul backhaul links (up to 5‑8 km) in dense urban areas. The 23 GHz band offers abundant spectrum, making it suitable for clusters of small cells and macro sites where frequency coordination is tight. With XPIC, a single ODU can replace two separate radios, reducing tower space and antenna count while delivering double the throughput.

Typical applications include mobile fronthaul/backhaul for LTE‑Advanced and 5G NR, enterprise connectivity for campus networks, and temporary event coverage where rapid deployment is needed.

Integration and Management

The ODU is managed through the 9500 MPR IDU, which provides a web GUI, CLI, and SNMP. It reports real‑time RSL, modulation level, and error statistics. The unit supports both 1+1 and 2+0 configurations for protection and capacity aggregation. Advanced features like carrier‑grade Ethernet OAM (IEEE 802.1ag, Y.1731) enable fault and performance monitoring at the service layer.

Software licensing allows upgrading to higher capacities or enabling XPIC as the network grows, providing investment protection.

Reliability and Environmental

Built with military‑grade components, the ODU withstands extreme temperatures, humidity, and salt spray. It includes integrated lightning surge protection and a comprehensive self‑diagnostic routine that runs at startup and periodically. MTBF exceeds 180,000 hours.

Conclusion

The Alcatel‑Lucent 9500‑MPR ODU MPT‑HC V2 (3DB20474BAAB04) represents the pinnacle of microwave backhaul technology. Its exceptional capacity, advanced XPIC, and adaptive features ensure that it meets the ever‑growing bandwidth demands of modern mobile networks while maintaining carrier‑grade reliability.
