ANDOVER, Mass., Nov. 21, 2023 (GLOBE NEWSWIRE) -- Casa Systems (Nasdaq: CASA), a market leader in cloud-native network solutions serving Tier 1 and regional service providers worldwide, today announced that Casa Systems’ Virtual CCAP (vCCAP), coupled with the company’s RPD200 (Remote PHY Device) solution, has secured a world’s first in performance that enables cable modems to achieve full utilization of the extended spectrum available via the DOCSIS 4.0 specification at the recent CableLabs® and Kyrio® Interop·Labs DOCSIS 4.0 Technology event. This successful demonstration showcased the interoperability of Casa Systems’ vCCAP and RPD solution with third-party DOCSIS 4.0 cable modems achieving remarkable extended spectrum utilization - up to 1.8 GHz downstream and 396 MHz upstream. This breakthrough not only marks a significant stride in technological innovation but also provides operators with unparalleled flexibility to deploy multi-gigabit broadband services, paving the way for the 10G era.

This latest innovation demonstrates Casa Systems’ sustained commitment to helping service providers across all access technologies – mobile, cable and wireline – embrace a cloud-native future to bring the best broadband technologies to customers around the world. Casa Systems’ unique software design uses programmable FPGAs that are tailored to flexibly meet operator requirements with the ability to accelerate time to market of new features quickly and easily as their networks evolve. The successful demonstration of full utilization of extended spectrum DOCSIS (ESD) will accelerate cable operators’ efforts to deliver competitive best-of-breed services to commercial and residential customers.

“Through our continuing commitment to innovation in the cable industry sustained over the past 20-plus years, Casa has been helping cable operators move their industry forward,” said Casa Systems CEO Michael Glickman. “The unprecedented performance of our market-leading access technologies, including our vCCAP, vBNG and mobile packet cores, will fundamentally shift the competitive landscape across the telecom industry, allowing providers to deliver multi-gigabit services as well as set a sustainable foundation for network evolution as we shift to a virtualized future.”

Casa Systems’ breakthrough achievement in unlocking superior cable performance comes at a time when the company is sharpening its focus on optimizing the performance and throughput of the subscriber core across cable, wireline, and mobile access technologies. The company has recently realigned all technology teams under Chief Product Officer Colin Kincaid as Chief Technology Officer Weidong Chen, a Casa Systems founder celebrated for shaping the company's core competencies in the cable industry, transitions to an advisory role with the company.
