Viavi solutions is the test equipment manufacturer spin off of JDSU after it split into two companies namely Viavi and Lumentum. Since JDSU started making test equipment, it acquired many Test Equipment manufacturers trade marks namely TTC , Acterna, Wandel and Golterman (WG), Wavetek, Circadiant, Innocor and others all involved in test solutions for the telecom market.
Simbol Test Systems has a lot of experience in the troubleshooting, repair and calibration of JDSU/Viavi equipment. When Viavi was created, it was decided it would no longer support many of the legacy JDSU branded optical test products such as RM meters, Attenuators, Optical Switches, etc. An agreement was reached between Viavi and Simbol so JDSU Customer support would refer customers in needs of service for such equipment to Simbol. Over the years, Simbol also gained experience in the repair and calibration of Viavi branded products mostly its MAP modular test platform and the numerous modules that can be fit in that mainframe.
