Q1: Phapano ke efe pakeng tsa EPON GPON OLT le XGSPON OLT?
Phapang e kholo ke hore XGSPON OLT e tšehetsa GPON/XGPON/XGSPON, Lebelo le Lebelo.
Q2: Ke li-ONT tse kae tseo EPON kapa GPON OLT ea hau li ka hokelang ho tsona
A: E ipapisitse le palo ea likou le karolelano ea optical splitter.Bakeng sa EPON OLT, boema-kepe bo le 1 ba PON bo ka hokela ho 64 pcs ONTs boholo.Bakeng sa GPON OLT, 1 PON port e ka hokela ho 128 pcs ONTs boholo.
Q3: Sebaka se seholo sa phetisetso ea lihlahisoa tsa PON ho moreki ke eng?
A: Bohole bohle ba phetisetso ea pon port ke 20KM.
Q4: Na u ka tseba phapang ea ONT & ONU ke efe?
A: Ha ho na phapang ea bohlokoa, ka bobeli ke lisebelisoa tsa basebelisi.U ka boela ua re ONT ke karolo ea ONU.
Q5: FTTH/FTTO ke eng?
FTTH/FTTO ke eng?
