Main frame with cable and antenna analyzer module (12.5 MHz to 6 GHz) and single-mode OTDR module with accessories The VIAVI OneAdvisor 800 is designed to meet the evolving needs of service providers, field technicians and contractors as they scale 5G infrastructure. OneAdvisor 800 allows cell site technicians to test fiber, RF, and CPRI/Ethernet from a single instrument, replacing multiple independent tools (OTDR, CAA, Fiber Scope) and significantly reducing the total cost of ownership. The instrument’s workflow user interface carefully guides technicians through a pre-configured common test process, making sure that technicians complete the job in the same way and to the same specifications. With OneAdvisor 800, tower hands get built-in guidance, automatic test configuration, pass/fail results, and a single closeout report every time, at every site. OneAdvisor helps you get in, get out, get paid.
