Alcatel-Lucent 9500-MPR ODU Radio MPT-HC V2 3DB20476BAAB04 23 GHz Microwave Outdoor Unit

The Alcatel-Lucent 9500-MPR ODU Radio MPT-HC V2 is a state-of-the-art outdoor unit (ODU) designed for point-to-point microwave links in the 23 GHz frequency band. With its high capacity, advanced modulation schemes, and ruggedized enclosure, this ODU is the preferred choice for mobile backhaul, enterprise connectivity, and public safety networks requiring reliable, high-throughput wireless transport.

Product Description

This ODU, identified by the full product code 9558HC MPT-XP 3DB20476BAAB04, is part of Alcatel-Lucent's 9500 MPR series, which includes both indoor and outdoor microwave radios. The MPT-HC V2 variant features enhanced processing power and supports up to 4096 QAM, delivering data rates exceeding 1 Gbps over a single 56 MHz channel. The unit integrates seamlessly with the 9500 MPR indoor unit (IDU) via an IF cable, providing flexible deployment options for hub sites and remote terminals.

The 23 GHz band offers excellent spectrum availability and allows for compact antenna designs, making the ODU suitable for urban environments where tower space and frequency resources are limited. The unit's built-in automatic transmit power control (ATPC) and adaptive modulation ensure optimal link performance even under fading conditions.

Application in Mobile Backhaul

In 5G and LTE networks, the 9500-MPR ODU provides the high-capacity backhaul required to aggregate traffic from small cells and macro sites. The 23 GHz band is well-suited for short to medium hops (2-10 km) in dense urban areas. The ODU's low latency and high throughput enable seamless support of delay-sensitive services such as voice, video streaming, and critical IoT data. The MPT-HC V2's cross-polarization interference cancellation (XPIC) further doubles the link capacity by reusing both polarizations, a valuable feature in congested spectral environments.

Installation and Maintenance

Installation is simplified by the unit's lightweight construction and integrated mounting bracket. Alignment is assisted by an audio tone and RSSI indicator. The ODU includes comprehensive diagnostics, such as spectrum analysis, link margin measurement, and alarm logging. Firmware upgrades are performed remotely via the IDU, reducing site visits and operational costs.

Conclusion

The Alcatel-Lucent 9500-MPR ODU Radio MPT-HC V2 9558HC MPT-XP 3DB20476BAAB04 is a high-end microwave outdoor unit delivering exceptional performance in the 23 GHz band. Its combination of high capacity, adaptive modulation, and robust environmental tolerance makes it an indispensable component for modern wireless backhaul networks.
