NPN stands for Negative-Positive-Negative, and in the telecom industry, it refers to a type of bipolar junction transistor (BJT) configuration. In an NPN transistor, the middle layer of the transistor is made of p-type semiconductor material, sandwiched between two layers of n-type semiconductor material. This configuration allows the transistor to amplify electrical signals and control the flow of current. NPN transistors are commonly used in amplifiers, oscillators, and digital circuits in telecommunications equipment due to their high efficiency and versatility.
