VIAVI Solutions has introduced the mOSA Module, adding optical spectrum analysis to the VIAVI Multiple Application Platform (MAP) optical manufacturing test system. The mOSA complements existing VIAVI solutions for optical power measurement, switching, signal conditioning and test automation.

The new MAP mOSA Module offers web and touchscreen user interfaces and claims a 30% improvement in measurement resolution as compared to similar products on the market. A member of the LightDirect family of hot swappable test modules, the single slot mOSA is smaller than legacy optical spectrum analysers, reducing the automated manufacturing test system footprint by up to six rack units. Joining the seventeen application modules already released for the VIAVI MAP System, the addition of the mOSA Module allows customers to leverage the full integrated power of the optical test platform.

“Optical communications manufacturers are racing to keep up with demand for next generation coherent and ethernet optical interfaces. Simultaneously, testing precision continues to increase, while pressure to hit aggressive cost targets has never been higher,” said Tom Fawcett, Vice President and General Manager, Lab and Production Business Unit, VIAVI. “Our new mOSA optical spectrum analyzer leapfrogs the competition in both performance and density, perfectly complementing the VIAVI MAP system that delivers unmatched scalability, efficiency and precision to meet escalating demands for optical manufacturing testing.”
