Hi:
I just learning communication technology, I saw the GPON farthest distance ranging technology has made all the ONU in logic, which based on TDMA technology makes when the beam splitter meet do not conflict, TDMA I used to know some, definition is know, but now also is very confused, dwell with logical distance, assuming not TDMA is to ensure that at the same time to the beam splitter, then with TDMA, in their own time slot to send, how to ensure an ONU time slot is not coincidence?
The beam splitter is passive, that is, TDMA time slot split occurred in ONU, I don't know if I understand right, one thousand have an ONU in TDMA time slot, and another time slot is just the same, no conflict? I think I understand there should be a problem, I please click on a minute, thank you
