Viavi Solutions, an American network test, measurement and assurance technology company, offered to acquire EXFO, a company that designs and manufactures test instruments and service assurance products for fixed and mobile telecom networks, for $430m. "There are clear strategic merits for combining VIAVI and EXFO to build the leader in communications test and measurement for the next decade. The strength of the combined teams and technology, combined with significantly greater scale and financial resources, would enable strong investment in growth while achieving greater operating leverage than either company could do alone," Viavi.
