ZTE Unveils World's First Multi-ONU Burst 200G-PON Prototype

• ZTE unveiled the industry's first multi-ONU burst 200G-PON prototype at MWC Barcelona 2026, achieving a groundbreaking 200 Gbps transmission rate
• Innovative optical signal "flash switch" technology enables nanosecond-level burst switching and 50ns frame recovery, addressing key industry challenges and paving the way for future 200G-PON standards

Barcelona, Spain, March 4, 2026 - ZTE Corporation (0763.HK / 000063.SZ), a global leading provider of integrated information and communication technology solutions, today unveiled the industry's first multi-ONU burst 200G-PON prototype at MWC Barcelona 2026, achieving a transmission rate of 200 Gbps.

The introduction of coherent technology into 200G-PON significantly enhances transmission speed and unlocks spectrum potential. However, the P2MP architecture of PON systems poses a major challenge. Coherent transmission is typically used for continuous signals, while PON uplink involves short bursts from multiple ONUs, imposing extremely high requirements on both transmission and reception. ZTE's newly released prototype addresses this critical challenge through breakthrough innovations, achieving seamless integration of coherent technology with the P2MP architecture, delivering both performance and efficiency gains.

ZTE has pioneered an innovative optical signal "flash switch" technology, enabling nanosecond-level on-off switching of burst frames at the transmitting end. This advancement dramatically improves burst signal switching gain while ensuring zero interference between multiple ONU burst frames, effectively addressing the industry challenge of rapid start-stop control in high-speed optical signals. At the receiving end, ZTE achieved ultra-fast 50ns frame recovery, substantially reducing transmission overhead and boosting throughput, thereby supporting massive concurrent terminal access with high efficiency.

This prototype release marks another milestone in ZTE's continuous innovation in optical access. It underscores the company's leadership in global optical communications and provides critical technical support and practical reference for the development and refinement of international 200G-PON standards. Looking ahead, ZTE will continue to advance optical communication technologies, deepen global industry collaboration, actively participate in standards development, and drive the evolution of the 200G-PON ecosystem—laying a solid all-optical foundation for the digital economy.
