Industrial Ethernet PHY

In audio systems, speakers and amplifiers are often the focus of discussion, while the audio transformer, a crucial component, is frequently overlooked. In reality, it plays an indispensable role in ensuring sound purity, reducing background noise, and ex

Why do IP-camera Ethernet ports drop offline and blow dead every storm season? VOOHU breaks down the three jobs of the RJ45 port—LAN-transformer isolation & PoE current rating, PoE power-transformer sizing for 802.3af/at/bt, and coordinated GDT/TVS/ESD surge protection—with a real part-number selection table for reliable outdoor ports.

On July 3, 2026, the three‑day electronica China came to a successful close at the Shanghai New International Expo Centre. VOOHU Electronics (VOOHU) presented its “Eight Major Solutions” and a complete portfolio of communication electronic com

100Mbps Ethernet Surge and Static Electricity Protection Standard Circuit Design ReferenceThis solution is a 100Mbps Ethernet standard solution from VOOHU Electronics Technology. The company has focused on communication electronic components for over 8 ye

With the rapid development of smart manufacturing and the Industrial Internet of Things (IIoT), industrial communications are moving towards high-speed and intelligent technologies. Industrial automation equipment requires real-time, efficient transmission of large amounts of data to achieve precise control and collaborative operations. Industrial Ethernet fieldbus, with its high speed, high reliability, and strong compatibility, has become the mainstream choice for industrial communications and is widely used in smart manufacturing, smart factories, industrial automation, and other fields. T

Gigabit Ethernet ports on industrial gateways and PLCs often share a cabinet with VFDs and switching supplies, where ground potential differences drive ground loops and common-mode noise couples into the pairs. This guide dissects the physical layer and gives in-stock VOOHU selection answers.
