Alcatel‑Lucent 9500‑MPR ODU MPT‑HC V2 23GHz Microwave Radio – 9558HC MPT‑XP
The Alcatel‑Lucent 9500‑MPR ODU MPT‑HC V2 is a cutting‑edge microwave outdoor unit operating in the 23 GHz band. With product code 3DB20476BAAA04 (also designated 9558HC MPT‑XP), this second‑generation radio delivers industry‑leading capacity through advanced cross‑polarization interference cancellation (XPIC), adaptive modulation up to 4096 QAM, and wide channel bandwidths up to 112 MHz. It is purpose‑built for mobile backhaul, enterprise connectivity, and high‑availability trunking in dense urban environments.
Architectural Overview
The ODU integrates a high‑performance modem with forward error correction (LDPC) and a low‑phase‑noise synthesizer, ensuring exceptional spectral efficiency and link stability. The MPT‑HC V2 platform supports both pure‑packet and hybrid TDM/packet modes, allowing seamless migration from legacy SDH/SONET to all‑IP transport. The unit features a built‑in 10 Gigabit Ethernet interface to the indoor unit (IDU) and a 4‑port Gigabit switch for local aggregation of eNodeB traffic.
XPIC technology enables simultaneous transmission of two independent data streams on orthogonal polarizations, effectively doubling the throughput without requiring additional frequency channels. This is particularly valuable in the 23 GHz band, where spectrum is often congested and licensing costs are high. The radio also incorporates hitless automatic transmit power control (ATPC) and adaptive coding and modulation (ACM) to maintain optimal performance during rain fade or multipath fading.

Deployment Scenarios
This ODU is ideal for high‑capacity mobile backhaul in 5G NR and LTE‑Advanced networks, connecting macro cells and small cells to aggregation hubs. The 23 GHz band provides abundant spectrum for multi‑gigabit links over distances up to 8 km. It is also used for campus backbones, connecting buildings across a corporate site, and for temporary event coverage with rapid setup.
With support for 1+1 protection (hot standby) and 2+0 configuration (dual‑polarization with XPIC), the radio offers flexibility to balance capacity and availability for critical infrastructure.
Management and Maintenance
Configuration and monitoring are performed through the 9500 MPR IDU's web GUI, CLI, or SNMP. The ODU reports real‑time parameters including received signal level, SNR, modulation, and XPIC cancellation depth. Built‑in loopback and spectrum analyser tools facilitate installation and troubleshooting.
Reliability and Compliance
Designed with redundant power paths and surge protection, the unit meets Telcordia GR‑3160, ETSI EN 300 019, and NEBS Level 3 standards. MTBF exceeds 170,000 hours.
Conclusion
The Alcatel‑Lucent 9500‑MPR ODU MPT‑HC V2 23GHz (3DB20476BAAA04) offers a future‑proof solution for high‑capacity microwave backhaul. Its combination of XPIC, wideband modulation, and robust design ensures carrier‑grade performance for the most demanding transport networks.
