Viavi Solutions has introduced its latest solution, the ONE-1600, to meet the testing and validation demands of the new 1.6 terabit per second (Tb/s) ecosystem. This module, based on 224G SERDES technology, joins the ONE LabPro platform, which already includes the HSE-800 800Gb/s test module. It supports OSFP1600 and QSFP-DD1600 form factors.
The demand for higher bandwidth and scale, driven by applications like artificial intelligence (AI), machine learning (ML), high-performance computing (HPC), and quantum computing, has posed significant challenges for the industry. This rapid advancement necessitates advanced instrumentation for accurate and efficient deployment and testing.
Dr. Vladimir Kozlov, CEO and Chief Analyst at LightCounting, commented on the shift, “Use of optical connectivity in AI clusters accelerated adoption of 1.6Tb transceivers and 224G SERDES. LightCounting increased forecast for these products to a million units in 2025, up from tens of thousands in 2024. We have never seen such a sharp ramp for new products. This will be a stress test for the whole supply chain.”
The ONE LabPro platform integrates physical layer insights with multi-port, multi-flow data and control plane Layer 2/3 Ethernet testing. The system supports up to 64 x 1.6Tb/s test ports using ONE-1600 modules or 128 x 800Gb/s test ports using HSE-800 modules, managed by a single controller. This allows for synchronized mixed combinations of test modules, with full breakout capabilities, multi-user logical port support, and single-user per logical port granularity. It also features a contemporary, web-based user interface and a next-generation, Python-based automation framework, enabling advanced traffic generation and analysis.
Osa Mok, Chief Marketing Officer of InnoLight, expressed the company’s commitment, stating, “InnoLight has invested significantly in development of 1.6T products based on 224G SERDES technology and we are happy to announce our next-generation 1.6T optics. Our new 1.6T optics enable cloud operators to rapidly upgrade their compute and networks to meet end customer demand. VIAVI testing solutions have accelerated our development and assured product quality.”
Hui Xu, Group Vice President of Research and Development for Cloud and Networking at Lumentum, added, “Our 1.6T transceiver modules and our leadership in foundational high-speed indium phosphide photonic devices and chip-scale packaging will enable hyperscaler cloud operator and AI infrastructure provider customers to take their next steps in scaling their AI and ML solutions. VIAVI is an important partner, providing key product testing and verification solutions aiding in our product development programs and, ultimately, in delivering our advanced solutions that address rapidly growing customer needs.”
Tom Fawcett, Senior Vice President and General Manager, Lab & Production at Viavi, shared the company’s enthusiasm for the ONE-1600 development, stating, “VIAVI is pleased to support the growing 1.6T development ecosystem with the ONE-1600 testing module. Our ONE LabPro platform now supports 1.6Tb/s data rates on 224G SERDES in an innovative platform that will help our customers deliver on their aggressive, high-speed Ethernet roadmaps.”
