PON Key Technology TDM Time-division multiplexing Introduction

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.

down stream TDM

Downdream,the data packet is sent to all the ONU as forecast mode. Every user can receive the data.

upstream TDM

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.

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
