Network Port

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
