SONT, a high-speed optical module developer and producer based mostly in China, options merchandise focusing on the telecommunications and knowledge communications markets, alongside a complete suite of R&D and quantity manufacturing capabilities within the area of 100G-800G optical modules. Amid the accelerating AI knowledge middle buildup, the corporate has ramped up adoption of its 800G and higher-speed optical modules, whereas strengthening its technological readiness for SiPh and low-power connectivity architectures.

Crealights Expertise
Crealights Expertise attended this yr’s expo below the theme “Full-Spectrum AI Compute Interconnects,” focusing on purposes in AI knowledge facilities and hyperscale compute clusters. By way of reside demonstrations, bodily samples, and 3D fashions, the corporate showcased the great capabilities of its domestically developed AI compute infrastructure.

At this yr’s exhibition, Crealights Expertise highlighted its in-house 6.4T NPO mild engine answer tailor-made for hyperscale AI clusters comprising 10K processors and past. By overcoming technical bottlenecks associated to superior multi-chip modules (MCM), this answer provides three foremost benefits: excessive velocity, low latency, and excessive density, rising as a essential interconnect answer for next-generation super-node infrastructures. Attendees had the chance to expertise the efficiency of top-tier interconnect purposes by tangible, testable, and verifiable means.

Furthermore, Crealights Expertise demonstrated interoperability testing of its 1.6T OSFP224-IHS 2×DR4 SiPh module with optical switches. It additionally exhibited its full sequence of 200G/lane SiPh modules, showcasing the sequence’ confirmed capabilities from R&D to mature mass manufacturing.

Underpinning these merchandise is Crealights Expertise’s personal “Wafer-In, Module-Out” (WIMO) built-in platform. The corporate has developed the total suite of core applied sciences spanning SiPh chip design, wafer testing, packaging and coupling, and module manufacturing. Following the supply of SiPh wafers, the workflow of wafer-level testing, dicing, thinning, sorting, mild engine meeting, and closing testing is accomplished totally in-house.

This yr, Crealights Expertise additionally exhibited its in-house SiPh chips and demonstrated a full-stack, closed-loop know-how roadmap spanning chips and modules. By way of product improvement, the corporate provides a complete lineup of 400G-1.6T SiPh modules, complemented by ancillary options, akin to energetic optical cables (AOC), energetic electrical cables (AEC), and liquid-cooled optical modules. This portfolio covers interconnect eventualities throughout all scales, together with intra-rack, rack-to-rack, and inter-cluster connectivity, whereas co-developing a seamless know-how roadmap with 6.4T NPO mild engine options. Collectively, Crealights Expertise supplies one-stop full-lifecycle interconnect options for AI clusters, spanning present deployment to future iterations.

At CIOE 2026, gamers throughout the whole optical communications worth chain collectively demonstrated their presence and technological advances in AI computing purposes. Notably, Accelink and Crealights Expertise delivered reside demonstrations of 6.4T NPO mild engines, whereas Eoptolink, Linktel Expertise, and Luxshare Precision showcased their 1.6T-12.8T optical modules and XPO options. The exposition additional featured core optical chips, together with 200G EMLs, VCSELs, and CW LDs from Everbright, ZJeagles Comsemi, and Shijia Photons, alongside silicon photonics platforms developed by Tower Semiconductor, GlobalFoundries, and UMEC.

The prevailing high-speed evolution has turn into a bellwether throughout the venue, as demonstrated by the upscaling of 800G connectivity deployments, the accelerated adoption of 1.6T connectivity, and intensive early-stage R&D efforts into 3.2T, 6.4T, and 12.8T architectures. Competing know-how pathways, together with CPO/NPO/XPO, silicon photonics, OCS, hollow-core fiber, and LPO/LRO, shared the highlight, signaling that the shift from the copper to optical interconnects has materialized from {industry} forecasts into engineering actuality. Most notably, Chinese language suppliers have developed globally aggressive merchandise throughout practically each essential part of the worth chain, starting from chips and elements to modules, tools, and take a look at devices. Past their position as “connectivity elements,” optical interconnects are rising because the bedrock of AI computing techniques. Amid this AI-driven momentum, China’s optical communications {industry} is ushering in a brand new cycle, evolving from a follower place to parity, and in choose segments, assuming a number one position on the worldwide stage.
