Network Port

In data communication systems, the selection of physical layer components directly affects port signal integrity, reliability, and cost. From 10G/25G ports in core switches, to PoE powering and lightning protection in industrial outdoor equipment, and to

Nowadays, more and more devices have local area network (LAN) connectivity. To facilitate communication, the simplest solution is to power the devices via a LAN cable (Power over Ethernet), thus eliminating the need for a separate power supply.PoE Transfo

When choosing a network transformer, you only look at speed, packaging, and PoE current, but the prototype repeatedly overturns in negotiation, packet loss, radiated emission, and temperature rise? The problem often lies in the few manual parameters that are skipped. VOOHU explains the five most critical parameters of the network transformer data manual - open-circuit inductance OCL, insertion loss, return loss, common mode rejection ratio CMRR, and DC resistance DCR - one by one: which test bench faults each corresponds to, how to read the numbers, and a quick checklist for selection based on

Overview of Ethernet Interface Hardware Architecture A typical Ethernet hardware interface consists of the following parts: CPU/MCU: Main control system, responsible for upper-layer protocol processing. MAC (Media Access Control): Media access contr
