HELLO RANJEET..
Thanks for sharing many important points but here i would like to ask you in what context you mean that All the TWDM ONTs must be colorless..
Which does it imply..??
Does it have any importance with reference to selection of the the transceiver section of the Optical Line Terminal Units (OLT) and Optical Network Terminals (ONUs) in TWDM-PON..?
I would appreciate if you explain a little further on this..
Thanks & regards
