This simply means that multiple test sets are required. The Network & Service Companion is a new category of compact hand-held device combining multiple test interfaces (PON, Ethernet, WiFi) with the VIAVI ‘OneCheck’ application concept to make network validation and high speed (Gigabit) service testing a simple and speedy process for all frontline techs and installers, be they beginner or expert.Ī single high-performance tool that allows techs to operate in multiple network environments and applications allowing network delivery and service performance to be easily documented with clear and fast demarcation/segmentation of any issues in under a minute. Without the all-in-one tool, fiber tests need to be conducted at different stages of the network lifecycle, such as during construction, acceptance, and maintenance.
