Recently, in Hanover, Maryland, telecommunications company Ciena reached an agreement with Nubis Communications to acquire it for $270 million. Nubis Communications focuses on high-performance, ultra compact, and low-power optoelectronic interconnect products designed to support artificial intelligence (AI) workloads. This transaction will expand Ciena's product portfolio and enhance its ability to respond to more opportunities within data centers.

 



Nubis’ solutions complement Ciena’s existing high-speed interconnects portfolio and will enable new capabilities to support growing AI workloads by significantly increasing scale up and scale out capacity and density inside the data center. For Ciena, the Nubis portfolio includes two key technologies: electrical active copper cables, and co-packaged optics (CPO)/near-packaged optics.

Nubis’ compact, high-density optical modules support up to 6.4 Tbps full-duplex bandwidth, and are optimized for low-latency, low-power operations, making them ideal for scaling AI systems. Combined with Ciena’s high-speed SerDes, Nubis’ optical engines enable differentiated CPO solutions to address high-performance connectivity needs inside and between racks.

In addition, the acquisition will strengthen Ciena’s expertise inside the data center, with the addition of more than 50 engineers to Ciena’s R&D team.

Under the terms of the agreement, Ciena will acquire Nubis in an all-cash transaction for $270 million, subject to a customary purchase price adjustment mechanism for the amount of cash, debt, and net working capital of Nubis at closing, among other items. The transaction is expected to close during Ciena’s fiscal fourth quarter 2025 and is subject to customary closing conditions.
