• In pon, the transmission of downlink signal from olt to onu is not complex . usually, the information destined for onus are combined into a multiframe at olt via tdm before reaching the feeder fiber, and then broadcast to each onu via the passive optical demultiplexor . upon receiving the downlink multiframe signal, each onu takes out the part of information for itself only
