Serenity: SIVE is not just a CPO laser supplier, but a key player in the next-generation optical interconnect architecture

**Key Market Insight: Sivers Semiconductor (SIVE) Is Far More Than a CPO Vertical Expansion Laser Supplier, Per Serenity Research** June 21: Independent research firm Serenity published an article correcting a widespread market misperception about Sivers Semiconductor (NASDAQ: SIVE)—that it is solely a laser vendor for Co-Packaged Optics (CPO) vertical expansion. The report clarifies SIVE’s laser portfolio spans all next-generation optical interconnect architectures, including pluggable optical modules, horizontal CPO scaling, vertical CPO scaling, and NPO. The strongest evidence supporting this broader role comes from SIVE’s partnership with global manufacturing leader Jabil: the pair co-developed a 1.6T optical transceiver using continuous-wave (CW) lasers, which effectively bypasses the capacity bottleneck of electro-absorption modulated lasers (EML) while delivering lower power consumption. Jabil’s management has labeled this a significant competitive moat for the joint solution. Since Jabil’s announcement, multiple other pluggable optical module manufacturers have proactively reached out to SIVE to enter joint development or certification processes, per Serenity. These non-public developments could trigger new official announcements at any time. Critically, most optical module suppliers (excluding Lumentum) lack vertical integration, amplifying the importance of SIVE’s independent laser supply position. Looking at long-term sector timelines: - Horizontal CPO scaling (interconnecting optics across racks or clusters to expand data center network capacity) is slated to launch in H2 2026, with SIVE as the laser supplier for players like POET. - Vertical CPO scaling (boosting bandwidth between GPUs/accelerators within a single AI server or rack via CPO) will ramp up in H2 2027, driven by the Ayar and NVIDIA NVLink CPO ecosystem—seen as a core scaling inflection point for the entire optical interconnect track. From a supply chain perspective, Serenity emphasized SIVE’s leading edge among peer laser vendors: it has maintained multi-year design partnerships with key industry players including Marvell Celestial, Lightmatter, and Lightelligence. SIVE is also a reference laser supplier at GlobalFoundries (Gf) foundries, and major manufacturer O-Net is building ELS solutions based on SIVE’s technology to target supply contracts for Asia’s largest cloud operators. Starting in 2027, SIVE will be integrated into nearly all new optical interconnect architectures, earning it Serenity’s title as its top-picked critical laser bottleneck target. *BlockBeats Clarification: CPO horizontal expansion refers to interconnecting optics across racks or clusters for data center-level network expansion; CPO vertical expansion refers to increasing interconnect bandwidth between GPUs/accelerators within a single AI server or rack using CPO.*
