光環(huán)行器是一種三端口或四端口的光學(xué)裝置，其設(shè)計(jì)使進(jìn)入任何端口的光從下一個(gè)端口出口。這意味著，如果光進(jìn)入端口1，它是從端口2發(fā)射出來的，但是如果一些發(fā)出的光被反射回循環(huán)器，它不是從端口1出來，而是從端口3退出。光纖環(huán)行器被用來分離在光纖中向相反方向運(yùn)動(dòng)的光信號(hào)，例如在一根光纖上實(shí)現(xiàn)雙向傳輸。[1]由于其對(duì)輸入光功率和反射光功率的高度隔離以及它們的低插入損耗，光環(huán)被廣泛地應(yīng)用于先進(jìn)的通信系統(tǒng)和光纖傳感器的應(yīng)用中。
