A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32-128. A PON consists of an Optical Line Termination (OLT) at the service provider s central office and a number of Optical Network Units (ONUs) near end users. A PON configuration reduces the amount of fiber and central office equipment required compared with point to point architectures

詞法分析 1 試驗目的 設計,編制并調試一個此法分析程序,加深對此法分原理的理解. 2 試驗要求 1)待分析的簡單語言的詞法 * 關鍵字: begin if then while do end 所有關鍵字都是小寫. 2)運算符和界符: : = + * - / < <= <> > >= = ( ) # 3)其他單詞是標識符(ID)和整數型常數(NUM),通過一下正規式定義: ID=letter (letter|digit)* NUM=digit digit* 4)空格由空白,制表符和換行符組成,空格一般用來分隔ID,NUM,運算符,界符和關鍵字,此法分析階段通常被忽略. 3 各種單詞符號對應的種別碼如表所示
