Tencent recently released the 102.4T NPO Switch Design Reference Specification, making public its design plans covering system architecture, chassis structure, fiber management, and software operations. The switch carries 32 3.2T NPO modules and 32 ELSFP external light source modules, providing 128 800G MPO16 optical ports. Tencent says that, compared with traditional pluggable switches, total system power consumption is reduced by about 1000W and end-to-end transmission latency by nearly 100ns.
Why we recommend it: From switch system design to multi-source supply disagreements, the material shows the concrete tension between NPO's open, disaggregated approach and industry specifications that have yet to converge.

An Omdia report notes that pre-terminated fiber solutions are expanding from traditional FTTH scenarios into data centers, edge computing and smart cities. Its data show that cloud business is driving data center capacity growth of 25% per year, and AI development will further increase demand for fast, reliable fiber deployment. Pre-terminated solutions reduce field termination errors through improved connectors and plug-and-play designs, while Clearfield's vertically integrated manufacturing is used to respond to customer needs and reduce dependence on overseas logistics.
Why we recommend it: The deployment advantages of pre-terminated solutions and manufacturing integration cases complement each other, providing context for understanding how passive component suppliers expand from FTTH into data centers.

Ao Li, vice president of the China Academy of Information and Communications Technology (CAICT), said the optical communications industry is shifting from being driven by traditional telecom to being driven by AI computing, with next-generation communications networks and optical networks evolving in parallel. He noted that 1.6T is at the early commercialization stage globally, hollow-core fiber is already used for low-latency dedicated lines and cross-domain computing interconnects, and multi-core fiber is entering high-density data center cable scenarios. He expects optical circuit switching systems to form an optoelectronic hybrid architecture with electrical switching, while the relevant technology roadmaps continue to develop in parallel.
Why we recommend it: Comparing high-speed interconnects, hollow-core and multi-core fiber, and optical switching under AI computing demand provides context for understanding the engineering pace of each optical communications pathway.

Mao Qian noted that control over fiber demand has shifted from carriers to cloud providers, and preform expansion cycles make supply-demand gaps difficult to ease quickly through pricing. A report he released estimates that global optical fiber and cable demand will reach about 630 million fiber-km in 2026, while effective supply will be only 480 million to 520 million fiber-km, leaving a gap of about 110 million to 150 million fiber-km. Preform plant construction takes 18 to 24 months, and product mix shifts combined with supply constraints are pushing the industry from price competition toward value competition.
Why we recommend it: Linking cloud provider demand with preform capacity expansion cycles explains why structural shortages can persist even when nominal capacity is ample, providing a framework for comparing different fiber categories.

Mao Qian released the 2026 Global Optical Fiber and Cable Industry Development Report, stating that the global market is forming two fragmented systems led by the US and China, while Chinese companies' overseas expansion is shifting from absorbing excess capacity to exporting value. APC data show that Chinese companies' combined global share exceeded 45% in 2026, with North American prices at two to three times the global benchmark. The report forecasts that Chinese companies' share will exceed 50% by 2030, and warns of risks from key raw material supply and a supply-demand reversal after new capacity comes online.
Why we recommend it: The report places trade barriers, overseas capacity and customer lock-in within a single competitive framework, providing context for understanding how Chinese fiber companies are shifting from scale expansion to value export.

Speaking at the Global Optical Fiber and Cable Conference, Wen Ku said AI, computing power and data centers are reshaping fiber optic cable demand, and urged upstream and downstream players to establish long-term price negotiation mechanisms and expand capacity rationally. He noted that global fiber demand grew 4.1% in 2025, with data communications and data center-related demand up 76%, while expanding optical fiber preform capacity takes two years. Wen Ku warned that high prices could trigger a concentrated release of new capacity, recommending more long-term contracts and navigating price cycles through low-latency, low-loss, high-density technologies and diversified applications.
Why we recommend it: Links AI-driven changes in fiber demand to the preform capacity expansion cycle and price mismatches, providing industry context for why the current boom carries risks of overcapacity.
Researchers have developed and demonstrated a GaP-on-diamond hybrid nanophotonic platform enabling controlled interaction between photons and silicon-vacancy (SiV) centers in diamond. Using stamp transfer, the team fabricated more than 600 nanophotonic cavities on a diamond substrate with a yield of 99.5%, achieving cooperativity above 1 and a spin relaxation time exceeding 0.4 milliseconds, enabling single-shot readout of SiV electron spins. Next steps include connecting multiple devices on the same chip and demonstrating entanglement.
Why we recommend it: A transfer process that avoids etching the diamond balances device yield with spin-photon coupling, offering a concrete example of how quantum network interfaces could move toward scalable manufacturing.
