Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network).

Telephone components and accessories are used in telephone systems

LCR meters and impedance meters measures inductance (L), capacitance (C), and resistance or impedance (R

Scalar network analyzers measure the amplitude portion of scattering or S-parameters, reflection and transmission coefficients between the incident and reflection waves that describe a device’s behavior under linear conditions at the microwave frequency range

Network servers control and manage network resources such as files, printers, users, groups, etc

Telephones and cell phones convert voice or other sound signals into a form that can be transmitted to another device that receives and reconverts the waves back into sound

Network test equipment is used to test, probe, and analyze telecommunication, network and telephone systems
