All-In-One Cell Site Test Tool

One solution. One process. One report.


 OneAdvisor-800 allows cell site technicians to test fiber, coax, and RF from a single instrument, replacing multiple independent tools (OTDR, CAA, Fiber Scope) and significantly reducing the total cost of ownership. 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’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-800 helps you get in, get out, get paid.

1 Single-Mode, 2 Multi-Mode


  • Improved tool efficiency.  Replaces multiple independent tools (i.e. OTDR, CAA, Fiber scope, etc).
  • Broad coverage.  Covers all radios types (LTE and 5G) and topologies (Macro-cell, Small-cell, C-RAN, and/or DAS)
  • Scalable.  As a team’s test responsibility grows, so can the OneAdvisor platform with modular test components

OneAdvisor-800 Test Process Automation Benefits

  • Greater accuracy.  Complete test plans exactly to the specifications of the service provider with precise measurements.
  • Consistency. Test processes and workflows are defined centrally and “pushed” to test instruments, eliminating the variability of manual procedures and drives consistent, repeatable results, regardless of technician skill or experience level.
  • Lower Training Costs. Training focus shifts to the test process itself, which is faster and easier to learn, rather than on technical information that is generally time-consuming and overwhelming for new technicians.
  • Speed. Job Manager eliminates wasted technician time trying to remember which tests to run and how to run them
