In the PON (Passive Optical Networks), the data transmission from ONU (optical network unit) to OLT (optical line termination) in the up-stream direction employing the style of TDMA (Time-Division Mutiple Access), is the burst-mode transmission also.

• 在无源光网络(PON)中,在上行方向从各网络用户单元(ONU)到光线路终端(OLT)的数据传输采用时分多址(TDMA)的方式,也是突发数据包的传输。
