Network cable tester Network cable tester is mainly used to test whether the 8-core line of the network cable is on. There are many kinds of network cable tester. The most common one is a single function network cable tester. Some are more powerful and have a more intuitive LCD display. Some are multi-functional, such …
Wireless lapel microphone, a type of wireless microphone, has become popular recently. It is a small, small and portable microphone, usually worn in the location of the user's clothing lapel. It can be freed from the cable, and the user can do whatever he or she wants without worrying about the sound. It is generally …
Inductor is usually called the feeling, the self inductance coil is called inductance, mutual inductance coil is called transformer, they are all with enameled wire, cotton covered wire or plastic skin line in insulation skeleton or core (typically high-frequency transformer), iron core made of round a set series of electromagnetic induction of coaxial circle element, …
Video optical transceiver is the equipment that converts 1 to multi-channel analog video signals into optical signals through various codes and transmits them through optical fiber medium. As video signals are converted into optical signals through analog conversion and digital conversion technologies, video optical transceiver is divided into analog optical transceiver and digital optical transceiver. …

Hall element is a device that applies hall effect. The so-called Hall effect was discovered by American physicist Hall in 1879. It refers to the physical phenomenon of transverse potential difference when the magnetic field acts on the carriers in the current-carrying gold conductor and semiconductor. When electric current through the metal foil, if the …
Resistance is one of the most widely used circuit components, accounting for more than 30% of the total number of components in electronic equipment, and its quality has a great impact on the stability of the circuit. It is mainly used to stabilize and regulate current and voltage in circuits, and also used as a …
