OneAdvisor 800 Transport Platform

Field-ready network test platform up to 400G

OneAdvisor 800

The OneAdvisor 800 is a field-ready test tool that delivers all the test capabilities technicians and engineers need to install and maintain high-capacity networks up to 400G. Four-hundred gigabit Ethernet technology requires more energy and generates more heat than low-capacity networks. The OneAdvisor 800’s superior battery life and industry-leading heat dissipation make it perfectly suited to 400G testing in the field, including metro/core, data center interconnect, and business services testing. The OneAdvisor 800 features the same user interface as all in the T-BERD/MTS Family.
