,
LM241TW4, dual-mode ONU/ONT, ke e 'ngoe ea XPON optical network units, tšehetso ea GPON le EPON mekhoa e 'meli ea ho ikamahanya le maemo.E sebelisoa ho FTTH/FTTO, LM241TW4 e ka kopanya lits'ebetso tse se nang mohala tse tsamaellanang le litekanyetso tsa tekheniki tsa 802.11 a/b/g/n.E boetse e tšehetsa lets'oao la waelese la 2.4GHz.E ka fa basebelisi ts'ireletso ea ts'ireletso ea phetiso ea data e sebetsang hantle haholoanyane.'Me u fane ka litšebeletso tsa TV tse theko e tlaase ka boema-kepe ba 1 CATV.
XPON ONT ea 4-port e lumella basebelisi ho fihlella koung ea XPON ea inthanete e potlakileng, e arolelanoang le koung ea Gigabit Ethernet.Holimo 1.25Gbps, tlase ho 2.5 / 1.25Gbps, sebaka sa phetisetso ho fihlela ho 20Km.Ka lebelo la ho fihla ho 300Mbps, LM240TUW5 e sebelisa antenna e ka ntle ea omnidirectional ho eketsa marang-rang a marang-rang le kutloisiso, e le hore u ka fumana matšoao a se nang mohala kae kapa kae lapeng kapa ofising ea hau hape u ka hokahanya le TV, e ka ntlafatsang bophelo ba hau.
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?
Sebakeng sa kajeno sa dijithale se potlakileng, khokahano ea inthanete e tšepahalang le e potlakileng e fetohile ntho e hlokahalang.Ho fihlela tlhoko ena, Limee e lula e leka ka matla ho fana ka litharollo tse ncha.Layer 3 XGSPON OLT LM808XGS, e nang le likou tse 8 le 100G uplink, e hlaha e le mohanyetsi ea matla ho fana ka khokahanyo e sebetsang le e matla.

E na le ts'ebetso ea Layer 3, XGSPON OLT ena e tlisa melemo e mengata.E na le bokhoni ba ho tsamaisa le ho fetisa lipakete tsa data marang-rang a mangata, ho ntlafatsa ts'ebetso ea marang-rang le ho ntlafatsa boiphihlelo ba mosebelisi.Ts'ebetso ena e thusa ho laola sephethephethe hantle, ho netefatsa hore motho e mong le e mong ea ngolisitseng o fumana bandwidth eo a e abetsoeng ntle le tšitiso ea letho.
E 'ngoe ea melemo ea bohlokoa ea Layer 3 XGSPON OLT LM808XGS ke scalability ea eona.E na le likou tsa 8, e ka amohela palo e kholo ea ba ngolisitseng, e etsa hore e tšoanelehe bakeng sa lisebelisoa tse nyenyane le bafani ba litšebeletso tse kholoanyane.The 100G uplink e tiisa hore ha litlhoko tsa ba ngolisitseng li eketseha, marang-rang a ka sebetsana le sephethephethe se ntseng se eketseha ntle le ho sekisetsa tshebetso.
The Layer 3 XGSPON OLT LM808XGS e etelletsa pele ho ts'epahala le ts'ireletso ea marang-rang.E sebelisa liprothokholo tse tsoetseng pele le mekhoa ea encryption, ho netefatsa hore data ea ba ngolisitseng e lula e bolokehile ebile e sirelelitsoe ho phihlello e sa lumelloeng kapa litšokelong.Tsepamiso ena ea ts'ireletso e sireletsa tlhahisoleseling ea bohlokoa mme e fana ka khotso ea kelello ho bafani ba litšebeletso le ba ngolisitseng.
