Description
1. The coupler and the power splitter are used together, mainly to achieve a goal-to make the transmission power of the signal source to be evenly distributed to the antenna ports of the indoor distribution system as much as possible, so that the transmission power of each antenna port is basically the same.
2. In the microwave system, it is often necessary to divide the microwave power of one channel into several channels in proportion, which is the problem of power distribution. The components that realize this function are called power distribution components or couplers.
3. Optocoupler is a kind of electrical-optical-electrical conversion device that transmits electrical signals through light. It consists of two parts: a luminous source and a light receiver. The light-emitting source and the light-receiver are assembled in the same airtight housing, separated from each other by a transparent insulator.
