Lumentum announces improvements to 800ZR+ transceivers


The company says that the modules, which incorporate both indium phosphide PICs and silicon photonics, can now serve a broader range of applications

Lumentum has announced that it has made significant performance enhancements to its 800ZR+ transceivers, which it says enable the modules to serve a wider range of applications, including expanded use in metro and regional networks through the ability to interface directly into routers. The company added that the enhanced performance modes now make 400ZR+ and 600ZR+ operation suitable for true long-haul applications, with OSNR and dispersion tolerance enabling reaches exceeding 2000 km at 400G. Lumentum’s 800ZR+ transceivers were recently recognised in the 2024 Lightwave Innovation Review Awards and demonstrated in a 400 km+ amplified link at OFC 2024.

While optimising its latest generation of 800ZR+ modules, Lumentum says it has aimed to maximise performance while maintaining a compact QSFP-DD and OSFP form factor. These modules employ the company’s latest hybrid PIC technology, which incorporates both its indium phosphide PICs and silicon photonics. According to Lumentum, the performance and use case flexibility provided by these modules mark a significant step in the evolution of high-speed communications networks.

“Lumentum's unique photonic component capabilities and innovative module designs, together with our partners' latest generation coherent DSPs, enable us to provide solutions that dramatically increase scalability for both cloud and telecom network operators,” said Wupen Yuen, president of Cloud and Networking at Lumentum. “Our advancements also help address the challenges of scaling datacentre interconnects for the bandwidth needs related to artificial intelligence and machine learning.”

Marc Stiller, vice president of Product Line Management at Lumentum, added: “Our new 800ZR+ and 400ZR+ modules enhance cost-efficiency in applications spanning DCI to metro and long-haul applications, with significant improvements in optical power and optical signal-to-noise ratio. They represent a major advance in reducing cost and power per bit versus existing technologies.”
