RJ45 Plug

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

The driver type of an Ethernet PHY chip directly determines system signal integrity, anti-interference capability, and hardware design complexity. Voltage-mode and current-mode PHYs may appear to differ only in signal carrier, but they have fundamental di

In the information age, network communication technology is changing with each passing day, and high-speed and stable data transmission has become a key factor in the development of enterprises. As an indispensable component in communication equipment, ne

SFP fiber cage standards and corrosion resistance test The reliability of the SFP (Small Form-factor Pluggable) cage, as the mechanical and electrical interface of high-speed optical/electrical modules, directly affects the stability of the system. To ver

1、 Device Introduction A current transformer (CT) is a device used to measure and protect the current in a circuit. It converts high current into low current through the principle of electromagnetic induction for the purpose of measuring and protecting ci

In today's era of increasingly sophisticated and complex electronic devices, electromagnetic compatibility (EMC) has become a critical threshold for product reliability and market competitiveness. Both weak signals in high-speed transmission and the energy lifeline of stable power supply are constantly threatened by ubiquitous common mode noise. Such noise can, at best, cause data errors and audio-visual distortion; at worst, it may lead to system crashes or even endanger safety. As the "noise filter" of electronic systems, common mode chokes play an indispensable role. However, many engineer
