Hi . i am simulating GPON network . who can help me ? why output “optical delay component” no signal in upstream ? .Upstream faulty !!!!
Hi Hoat,
Can you please introduce the reference of your work? For downstream, there is one transmitter and each receiver receives part of that transmitter signal split by a spliter. But for upstream, the power of two upstream transmitters are combined. So which of these transmitters signal is the upstream receiver supposed to receive?

Hi Hoat,
In GPON, all ONUs for upstream uses the same wavelegnth and it is in TDMA manner which means each user transmits signal in a specific time slot. The upstream receiver would receive signal from all ONUs but not at the same time.
Hi Alistu .In your file ,This is TDM-GPON netwok simulation . In this system,it use 1 wavelength for downstream and 1 wavelengthfor upstream .I don’t get your point . Can you make it more clear?
Hi, the mistake is the iteration. U should set iteration to number 3 and than use the buffer selector =2.
Hi Hoat,
Because in TDM Pon, signals are transmitted and received according to different time slots given to all.
When there is no delay, and upstream and downstream time slots are same, and both gets overlap to each other.
Hence no output.
Thanks,
