frame signal meaning in English
帧信号
Examples
- 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 )
在上行信号回传时，由于从各onu端发出的光信号是经过长短不一的光缆到达局端，所以接收到的各路帧包信号的幅度和相位都不相同，各帧包信号之间的时间间隔很小，仅30bits左右，即192ns ( 155 . 52mbps时) ，且两路光功率之差可达15db ( g . 983建议) ，因此上行回传需采用特殊的“突发模式光发射和接收”器件。
