摘　　要：为了降低光纤到房间系统中光网络单元的数量和成本,提出了半双工模式收发机方案。该方案通过模式切换开关连通不同电路组件,实现通信系统的收发功能。同时,将该收发机与Wi Fi无线收发系统配合使用,形成了“光纤-无线”半双工收发系统架构,实现光信号和射频信号在光纤到房间系统中的传输。测试结果表明,设计的模式切换开关与收发机协同工作顺畅,在数据传输速率为5 Gb/s时,接收端信号眼图清晰,验证了半双工模式收发机方案的可行性。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.
