TDM is the abbreviation of Time-division multiplexing which is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time in an alternating pattern.
TDM is one of the PON technogloy, the data packet is transmitted in downstream and upstream via TDM technology.
Downdream,the data packet is sent to all the ONU as forecast mode. Every user can receive the data.
Updream, the data is sent to central site by burst mode, the data is sent by every ONU user when they have data need send. By the TDM technology, the datas are sent to OLT smoothly, no collision.
