Alcatel-Lucent 9500-MPR MPT-HC 23GHz 2/2P ODU Radio

The Alcatel‑Lucent 9500‑MPR MPT‑HC 23GHz 2/2P outdoor unit (part number 3DB20474BA) is a high‑capacity microwave radio featuring dual‑polarization (2P) and XPIC (Cross‑Polarization Interference Cancellation) technology. This configuration provides two independent channels on orthogonal polarizations, effectively doubling capacity without additional spectrum. It is designed for short‑haul, ultra‑high‑throughput links in dense urban networks, mobile backhaul, and data center interconnects.

Overview

The 23 GHz band offers wide channel bandwidths up to 112 MHz, and with 2/2P operation, the ODU can deliver aggregate throughput exceeding 2.4 Gbps. The unit features advanced digital signal processing, adaptive modulation up to 2048QAM, and robust FEC. It is housed in a compact, IP67‑rated enclosure for outdoor installation. The 2/2P configuration supports independent traffic on each polarization, providing flexibility for service differentiation.
