Solar panels get all the attention. But in a modern utility-scale solar installation, it is the trackers, inverters and cleaning robots that determine whether a farm meets its energy production targets. Trackers keep panels correctly oriented toward the sun, inverters convert what those panels produce into grid-usable AC power, and cleaning robots keep panel surfaces free of the dust and debris that silently erode energy yield between maintenance cycles. Between them, these three asset classes account for the majority of performance variability as well as costly failures.

Decision-makers evaluating linear pluggable optics (LPO) want numbers, not abstractions. If you're new to LPO, start with Blog 1: What Is Linear Pluggable Optics?, then come back here for the key quantitative parameters for 200G LPO deployment: power consumption by module type, optical reach, electrical loss tolerance, and host port calibration requirements.

Linear pluggable optics (LPO) is one of the most significant shifts in data center optical interconnect design in a decade — but the term still causes confusion. Is it a module type? A standard? A replacement for digital signal processing function or DSP-based optics entirely? This blog answers those questions from first principles.

The USB Type-C connector has become the universal interface of modern electronics. From laptops and smartphones to Artificial Intelligence (AI) computing platforms and industrial edge devices, USB Type-C supports both high-speed data transfer and high-wattage power delivery through a single cable. With the adoption of USB Power Delivery (USB PD) 3.1 and its Extended Power Range (EPR), (Table 1) VBUS line voltages have scaled from the familiar 20V/100W standard power range to 28V, 36V and 48V — enabling power delivery of up to 240W over a USB-C cable.

长期以来，亚洲一直被公认为物联网 (IoT) 采用最具活力的地区之一，而 2026 年亚洲科技新加坡展 (ATxSG) 让这一现实不容忽视。Semtech 和 LoRa Alliance® 将其完整的生态系统带到了此次活动中，反响完全符合团队的预期。
LoRa 联盟展馆汇聚了众多网关制造商和终端节点开发商，吸引了络绎不绝的人流，引发了有意义的技术交流，并且至少出现了一个具有里程碑意义的商业时刻，这表明 LoRaWAN® 在亚太地区取得了多么巨大的发展。
Here is a look back at everything that made ATxSG a milestone event for the LoRaWAN community.
