Alcatel‑Lucent 9500‑MPR ODU MPT‑HC 11GHz Microwave Outdoor Unit – 3DB20547ACAA01
The Alcatel‑Lucent 9500‑MPR ODU MPT‑HC is a high‑performance microwave outdoor unit (ODU) operating in the 11 GHz frequency band. With the specific variant 3DB20547ACAA01, this ODU is optimised for short‑ and medium‑haul backhaul links, providing carrier‑grade throughput, advanced modulation, and robust reliability for mobile and fixed wireless networks.
Product Description
This outdoor unit is part of the Alcatel‑Lucent 9500 Microwave Packet Radio (MPR) series, which combines TDM and packet‑based transport. The MPT‑HC (High Capacity) version supports channel bandwidths of 490, 500, and 530 MHz (selectable), enabling adaptive modulation from QPSK up to 2048 QAM. This flexibility allows operators to maximise capacity under favourable propagation conditions or to increase link robustness during rain fade by lowering modulation.
The ODU integrates seamlessly with the 9500 MPR indoor unit (IDU) via a standard IF cable. It includes a built‑in antenna interface (P100 flange) for direct connection to a parabolic antenna, reducing cable loss and improving system gain.

Key Features
Adaptive modulation and coding (ACM) for dynamic link adaptation.
Hitless automatic transmit power control (ATPC) to compensate for fading.
Integrated Ethernet switching with VLAN and QoS support.
Synchronous Ethernet and IEEE 1588v2 for mobile backhaul timing.
Advanced FEC (LDPC) for improved coding gain.
Cross‑polarization interference cancellation (XPIC) to double capacity (optional).
Deployment Scenarios
This ODU is ideal for cell site backhaul, connecting macro base stations and small cells to the aggregation network. The 11 GHz band provides a good balance between capacity and rain attenuation, making it suitable for moderate hop lengths (up to 10‑15 km). The high‑capacity version with 530 MHz spacing is particularly useful for sites with high traffic demand, such as urban hotspots and sports venues.
Operators can use the unit in both ring and hub‑and‑spoke topologies, with the 9500 MPR system supporting advanced protection schemes, including 1+1 HSB (hot standby) and diversity configurations.
Management and Diagnostics
The ODU is managed via the 9500 MPR IDU, which provides a web‑based GUI, CLI, and SNMP interfaces. It reports real‑time parameters such as received signal level (RSL), modulation, and BER. Built‑in spectrum analysis and loopback testing facilitate installation and troubleshooting.
Reliability and Environmental
Designed for harsh outdoor conditions, the unit features a ruggedized enclosure with corrosion‑resistant coatings and a weather‑proof cable connector. It includes surge protection and over‑voltage shutdown. Mean time between failures (MTBF) exceeds 150,000 hours.
Conclusion
The Alcatel‑Lucent 9500‑MPR ODU MPT‑HC 3DB20547ACAA01 is a versatile, high‑capacity microwave radio that meets the rigorous demands of modern wireless backhaul. Its advanced modulation, adaptive features, and robust design ensure reliable, high‑throughput connectivity for both 4G and 5G networks.
