Performance test of antenna matching circuit for intelligent optical distribution frame

The implementation of broadband strategy brings huge access network pipeline resources, which makes operators increasingly demand for low-cost and high-efficiency optical distribution network (ODN). There are many problems in the construction, maintenance and operation of traditional ODN. Seriously hinder the development of optical access network services, intelligent ODN technology should be shipped. Intelligent ODN can solve the problem of traditional ODN pipeline resource management confusion. Using RFID intelligent tag mode, the port information hardware circuit is designed. Antenna matching circuit. When changing a certain parameter in the circuit, the read/write performance of the antenna will change, which is expressed in the vertical distance and offset distance. By drawing the parameter relationship graph, the optimal working parameters of the circuit can be optimized.
