Building the Future of Optical Communication and Integrated SDV on Top of 2 Million Production References
Vehicle-network demo based on PCIe over Fiber and MIPI over Fiber.
Autolink presented a next-generation SDV architecture direction centered around optical communication and centralized computing.
Target SOP is 2028.
What stood out at Auto China 2026 was how Chinese Tier-1 suppliers, already equipped with mass-production references measured in the millions of vehicles, had begun proposing entire SDV architectures to global OEMs. The Autolink booth showed where China’s SDV Tier-1 suppliers stand today - connecting centralized computing, optical communication, AI-based development workflows, and global validation systems into a single direction.

Finding the Autolink booth at Auto China 2026 was not driven by particularly high expectations. A Qualcomm-based cockpit domain controller supplier - that alone did not initially seem very different from major Chinese Tier-1 suppliers such as Desay SV. According to Autolink itself, the company ranks second in market size.
"If you look at market share, Desay is still larger in scale."
That came directly from an Autolink representative. Yet the context in which the comment was made was what made it interesting. While downplaying its own size, the company's broader explanation pointed somewhere else entirely. Centralized computing, optical in-vehicle networking, AI-driven development automation, even robotics integration - Autolink sounded less like a conventional cockpit Tier-1 supplier and more like a company attempting to design the execution layer of the SDV future. The booth also raised one of the more pointed questions at Auto China: where Autolink aligns with - and diverges from - global Tier-1 suppliers such as Bosch, Aumovio, Hyundai Mobis, and LG Electronics.
Autolink's AI workflow structure based on AUTOSAR Agent. The company was integrating AI not into vehicle functions themselves, but into the development process. Autolink's integrated cockpit and driving computing platform, jointly displayed with Qualcomm at Auto China 2026, based on a single SoC architecture.
Millions of Vehicles Are Already on the Road
Autolink's shipment volume based on Qualcomm's third-generation 8155 platform has already exceeded two million vehicles. The fourth-generation Qualcomm platform entered SOP in October 2025 and is now being supplied as a standard domain platform for cockpit and ADAS applications. The company has accumulated production experience across more than 100 vehicle models and is supplying products in over 100 countries.
What matters is not just the number itself. Building this production track record under the extreme price competition and compressed development cycles of the Chinese domestic market is itself a capability. In the automotive industry, production references are often the prerequisite for future sourcing decisions. It is becoming increasingly difficult to deny that Chinese local suppliers have begun to reshape their position in the smart cockpit and integrated control domains traditionally dominated by global OEMs and Tier-1 suppliers.
Another industry source at the event quietly remarked:
"Global Tier-1 suppliers are already taking these solutions very seriously as competition."
Speed, Cost - and the Boundaries Autolink Draws for Itself
The most obvious strengths of Chinese cockpit Tier-1 suppliers remain speed and cost. Chinese companies are typically the fastest to integrate Qualcomm's latest SoCs into production vehicles. Autolink had already completed the transition from Qualcomm's third-generation to fourth-generation platform at mass-production level, and its centralized computing demo vehicle based on the fifth-generation 8797 SoC at Auto China represented a continuation of that trajectory.
"The 8797 single-chip structure integrates cockpit operation, autonomous-driving functions, and body control into one system."
This was not simply about adopting the latest chip. Integrating cockpit, ADAS, and body control into a unified computing structure is effectively the centralized E/E architecture envisioned for the SDV era. The DCU also incorporates AMD chips.
Autolink was also direct about why it continues to rely on Qualcomm amid the rapid rise of Chinese domestic SoC suppliers.
"Qualcomm's fifth-generation chips are already reaching the 3-nanometer level. In terms of process technology, there are still no domestic Chinese suppliers capable of reaching that level yet."
Chinese SoC suppliers are advancing rapidly, but Autolink's view is that a meaningful gap still exists at the leading-edge process level. Yet the company was careful to emphasize that the difference is not simply a matter of process nodes. Software ecosystem maturity, toolchain support, and global production-validation experience are equally significant factors.
"For high-performance centralized computing platforms requiring maximum performance, power efficiency, and unified global development support, Qualcomm remains one of the core platform choices for global production programs today."
Although Autolink says it is closely monitoring Chinese semiconductor suppliers and remains open to a multi-platform strategy, Qualcomm still serves as the benchmark for global production programs.
At the same time, Autolink does not position itself as a company attempting to dominate an entire ecosystem the way Huawei does. The company deliberately draws a line there.
"We are not trying to control the entire ecosystem. We provide up to the application layer within the cockpit system. Essentially, we provide total control solutions built around the chip."
What makes this positioning interesting is that, even while differentiating itself from Huawei, Autolink ultimately defines its role as a "centralized computing integrator." The company says it aims to provide OEMs with an open, flexible, and scalable computing foundation by supporting the integration of key domains including cockpit, ADAS, and body control - rather than pursuing a one-size-fits-all ecosystem approach.
"Rather than pursuing a one-size-fits-all ecosystem approach, we aim to become a trusted technology partner as global OEMs transition toward centralized architectures."
As the SDV era blurs the boundaries between cockpit, ADAS, and body-control domains, the role of integrating the vertical structure from compute to the application layer increasingly overlaps with the territory traditionally occupied by established Tier-1 suppliers.
Optical Communication and AI Workflows- How Far Has It Reached?
One of the technologies most prominently featured by Autolink at Auto China was optical communication inside the vehicle. Phrases such as "PCIe over fiber," "MIPI over fiber," and "Optical Communication High Performance ZCU" appeared repeatedly across the demo vehicle and booth displays - hard to miss by the time you had walked the full length of the booth.
The background is the data explosion of the SDV era. As vehicles move toward advanced automation, data volumes from cameras, radar, displays, and AI inference grow exponentially, and discussions about the long-term limitations of copper-based E/E architectures are already underway across the industry. Autolink frames the limitations of copper in four areas: physical constraints on bandwidth and transmission distance; complex EMC environments created by high-voltage EV powertrains; weight and packaging burdens from wiring harnesses; and latency challenges in high-level autonomous driving that demands real-time sensor fusion and rapid decision-making.
"Optical communication is not yet widely used in vehicles today, but we are applying it as a data-transmission technology for next-generation E/E architectures."
Autolink first revealed this direction at CES 2026 and has since integrated optical communication control modules developed in collaboration with a Chinese optical-module supplier. The system has completed AEC-Q104 certification and is considered vehicle-deployable. The target SOP is 2028 - though one representative added a candid caveat:
"We'll need to see how the order situation develops first."
At present, Autolink has secured orders for 8797 centralized computing units under a semi-centralized architecture, but discussions have not yet advanced to full system-concept deployment. The company is currently in conversation with one Chinese OEM and one European OEM about this direction.
The AUTOSAR Agent demonstration was also notable. The screen displayed a connected workflow spanning AUTOSAR requirements, configuration, testing, a workflow processing engine, a knowledge-base learning engine, and integration with DeepSeek and GPT. The intent was not to place AI inside the vehicle, but inside the vehicle-development process itself. Autolink identifies testing as the most practical near-term application.
"As SDV functionality rapidly increases in complexity, traditional manual approaches to test-case development, regression execution, and result analysis are becoming increasingly difficult to scale - and are emerging as a major bottleneck in the development process."
The same direction extended to a Rockchip-based on-device AI BOX and multimodal AI collaboration with ModelBest. Inside the booth, all of these elements were presented within an ecosystem framework connecting Qualcomm, AMD, Tata Elxsi, and robotics companies - not an attempt to do everything alone, but a positioning as a hub for integrated SDV execution.

Can It Go Global? - The Remaining Challenges
Autolink already operates technical-support and business hubs in Germany, Japan, the United States, and Korea. The head of the Korean office previously worked at Hyundai Motor. Another booth guide had spent years at SAIC. The presence of people who understand OEM development structures and validation requirements from the inside said something about how seriously Autolink views the Korean market - and its global ambitions more broadly. The collaboration with Tata Elxsi adds India's software-engineering depth to the mix, linking it with China's SDV hardware ecosystem as part of a deliberate effort to build an actual global network.
When engaging with global OEMs outside China, Autolink says two concerns come up consistently. The first is ecosystem compatibility: whether the company's products can integrate effectively with global software environments including foundational software, cloud services, toolchains, and cybersecurity frameworks. The second is regulatory compliance: whether varying market-specific requirements in functional safety, cybersecurity, and data privacy can be addressed systematically at the architectural level. Autolink says it has aligned its development processes with ISO 26262, ISO/SAE 21434, and where applicable, GDPR.
"Our goal is not simply to enter global markets, but to integrate locally within different regulatory and ecosystem environments."
Perhaps the most candid moment at the booth came in response to a question about the biggest barrier preventing fully centralized SDV architectures from reaching large-scale production. The answer was not technology - it was organization.
"Many OEMs' existing development processes, organizational structures, and supplier-management systems were originally built around distributed E/E architectures. Transitioning to centralized computing requires fundamentally rethinking the entire vehicle E/E architecture, software-development methodologies, and even testing and validation frameworks."
The underlying technologies may be maturing quickly. But the larger obstacle, in Autolink's reading, is the organizational inertia embedded in how traditional OEMs were built. Stated plainly at a trade show booth, it was a more honest assessment than most suppliers would offer - and an implicit acknowledgment that no amount of price competitiveness or technical advantage alone will be enough to move that needle.
The Question Chinese Cockpit Tier-1 Suppliers Are Now Asking
Autolink now stands between two worlds: the speed-and-cost competitiveness validated in China's domestic market, and the trust that the global market demands. For established global Tier-1 suppliers, what makes this shift uncomfortable is not simply the arrival of another low-cost competitor. Chinese companies are now approaching global OEMs not with cheaper parts, but with proposals for integrated SDV architectures - and those proposals already rest on production references measured in the millions of vehicles.
Autolink frames this not as competition, but as complementarity.
"The future direction is collaboration and complementarity. Chinese companies can contribute rapid innovation and efficient deployment, while global partners bring deep experience in program execution, system robustness, and process maturity. Ultimately, the companies that successfully combine China speed with global standards will be best positioned to lead the SDV industry forward."
That was precisely what the Autolink booth at Auto China 2026 put on display. Chinese cockpit Tier-1 suppliers can no longer be described simply as parts vendors. How far they will ultimately go in clearing the barriers that remain in the global market is still an open question - but it is no longer one that global Tier-1 suppliers can afford to leave unanswered.
