面向FTTR的低成本半双工模式收发机方案及关键技术OA北大核心

To reduce the number and cost of optical network units in fiber-to-the-room systems,a half-duplex transceiver solution is proposed.This solution realizes the transceiver function of the communication system by connecting different circuit compo-nents through a mode switch.At the same time,the transceiver is used together with the WiFi wireless transceiver system to form a"fiber-wireless"half-duplex transceiver system architecture,enabling the transmission of optical signals and radio frequency sig-nals in the fiber-to-the-room system.The test results show that the designed mode switch and transceiver work smoothly together,and the signal eye diagram at the receiving end is clear when the data transmission rate is 5 Gb/s,verifying the feasibility of the half-duplex transceiver solution.
