The Viavi ONA-800 oneAdvisor is a next-generation, modular, handheld test platform designed for the installation, activation, and maintenance of fibre optic access and transport networks. Built for field technicians, the ONA-800 combines a large colour touchscreen display with a rugged, lightweight chassis and an intuitive user interface to streamline complex testing workflows.
