Hello Kelly,
That is upstream. I changed the WDM demux Wavelength, now I am getting two eye diagrams properly.
I designed WDM-PON, datarate = 10Gbps, channel spacing = 100Ghz, one bidirectinal feeder fiber, add an optical delay between feeder fiber and AWG.
I am not getting the proper eye diagram. Do you have any idea, how to get ?
Thanks in advance.
