A compact instrument for techs and contractors handling installation, activation and troubleshooting of residential broadband, business services and Metro/Enterprise Ethernet services. Benchmarking network delivery, validating service performance and distribution while driving compliance to best practice to simply test everything anywhere


The Network and Service Companion (NSC-100) 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 and higher) service testing a simple and speedy process for all frontline techs and installers, be they beginner or expert.

A 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.
