    Tencent Publishes 102.4T NPO Switch Design Specification, a Step Closer to Large-Scale Deployment?

    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.

    NVIDIA and Cisco Jointly Define New USFP Pluggable Optical Module

    NVIDIA and Cisco jointly announced plans for the USFP (Ultra-Small Form Factor Pluggable) optical module on October 12. This high-density pluggable optical module supports 400Gb/s per lane and targets the scaling needs of next-generation AI factory networks, helping control network complexity, power consumption and cost as connection scale grows.

    Why we recommend it: The article explains the motivation behind two leading vendors jointly defining a new package form factor, helping assess the evolution of optical module formats for AI networks

    INMO AIR3 Recalled in US and Canada Over Temple Overheating, Testing Smart Glasses Thermal Design

    The US CPSC and Health Canada issued a recall on September 24 after the left temple of INMO AIR3 smart glasses could overheat during prolonged use. INMO has received 10 overheating reports, including burning sensations on the face and left ear. The recall covers about 1,643 pairs in the US and about 120 pairs in Canada, with free repairs and system updates offered as the remedy.

    Why we recommend it: The original paper gives the number of recalled units and incident reports, helping to understand the thermal engineering constraints of lightweight AI glasses
