During the period of up - stream transmission, the optical signals emitted from onu reach office center by fiber cable with different length. amplitude and phase of signals received are different. intervals between every framing signal are very short of only 30 bit, i. e. 192ns ( 155. 52mb / s ), the power difference of two signals can arrive at 15db ( g. 983 suggestions )
在上行信號回傳時，由於從各onu端發出的光信號是經過長短不一的光纜到達局端，所以接收到的各路幀包信號的幅度和相位都不相同，各幀包信號之間的時間間隔很小，僅30bits左右，即192ns （ 155 . 52mbps時） ，且兩路光功率之差可達15db （ g . 983建議） ，因此上行回傳需採用特殊的「突發模式光發射和接收」器件。
