Viavi Solutions has acquired Expandium, a provider of core network monitoring and assurance solutions powered by big data.

The company did not reveal financial terms.

The deal to buy Expandium, based in Saint-Herblain, France, enhances Viavi’s network assurance portfolio with a cloud-native virtualized solution offering, and will address the needs of virtualization initiatives at service providers.

The acquisition of Expandium adds cloud-native, microservices-based, and 5G-ready mobile core assurance technologies as Viavi continues to virtualize its NITRO Mobile portfolio of core and RAN assurance solutions.

Expandium uses techniques such as machine learning, stream processing and pattern detection within a platform that is vendor-independent and can connect to heterogeneous data sources, offering analytics and insights for network monitoring, troubleshooting, fraud detection, and more.

“Our major service provider customers are reporting that up to 75 percent of their networks have already been virtualized, and they are expecting their vendors to deliver products that will fit into the new fully virtualized 5G SA architecture,” said Sameh Yamany, chief technology officer of Viavi.

Viavi will support Expandium’s position in railway mobile services, including GSM-R and migration to LTE-R and FRMCS.

Viavi reported revenue of $266.6 million in its fourth fiscal quarter ended June 27, 2020 and $1.136.3 billion in its fiscal year 2020. Americas, Asia-Pacific and EMEA customers represented 36.5 percent, 32.4 percent and 31.1 percent, respectively, of total net revenue for the year ended June 27, 2020.
