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?
XPON dual band WiFi5 ONU ke sesebelisoa sa puisano se tsoetseng pele se kopanyang melemo ea theknoloji ea XPON, lihlopha tse peli tsa WiFi5, le ONU (Optical Network Unit).E etselitsoe ho fana ka khokahanyo ea inthanete e potlakileng le lits'ebeletso tse eketsehileng bakeng sa basebelisi ba bolulo le likhoebo tse nyane.
XPON, e emelang Passive Optical Network, ke theknoloji e sebelisang likhoele tsa fiber optic ho fana ka litšebeletso tsa data, lentsoe le video.E fana ka bandwidth e phahameng, latency e tlase, le scalability e phahameng, e e etsa tharollo e nepahetseng bakeng sa litlhoko tsa sejoale-joale tsa puisano.
Dual band WiFi5 e bua ka bokhoni ba ONU ba ho sebetsa ho lihlopha tse peli tsa 2.4GHz le 5GHz, tse lumellang likhokahano tsa mehala tse potlakileng le tse tsitsitseng haholoanyane.Sena se netefatsa hore basebelisi ba ka natefeloa ke ho phallela ka mokhoa o se nang moeli, lipapali tsa marang-rang, le mesebetsi e meng e matla ea bandwidth ntle le tšitiso ea letho.
Kaha ke sesebelisoa sa ONU, se sebetsa e le monyako pakeng tsa marang-rang a mofani oa litšebeletso le lisebelisoa tsa mosebedisi.E ts'ehetsa mekhoa e mengata ea marang-rang, ho kenyelletsa Static IP, DHCP, le PPPoE, e fa basebelisi monyetla oa ho khetha mokhoa oo ba o ratang oa ho hokahanya.
Ka lebelo la ho fihla ho 1200Mbps, XPON dual band WiFi5 ONU e fana ka khokahanyo ea WiFi e tšepahalang le e sebetsang hantle.E ts'ehetsa maemo a morao-rao a WiFi, ho kenyeletsoa 802.11b/g/n/ac, e netefatsang hore e tsamaellana le mefuta e mengata ea lisebelisoa.
Ntle le khokahano ea inthanete, XPON dual band WiFi5 ONU e boetse e fana ka lits'ebeletso tse tsoetseng pele tsa lentsoe.E tšehetsa SIP (Session Initiation Protocol) le H.248, e nolofalletsang basebelisi ho letsetsa VoIP (Voice over Internet Protocol) le ho fumana litšebeletso tse ling tsa lentsoe.
Ntho e 'ngoe e hlokomelehang ea XPON dual band WiFi5 ONU ke Dying Gasp Function, e fanang ka alamo ea ho tima.Sena se bolela hore ha motlakase o khaoha, ONU e tla romela letšoao ho lemosa mofani oa litšebeletso, e leng ho nolofalletsang ho nka khato ka potlako ho rarolla bothata.
Ho matlafatsa ts'epahalo ea ONU, e na le karolo ea boikhethelo e e lumellang ho tsoela pele ho sebetsa lihora tse 4 ntle le matla.Sena se netefatsa ts'ebeletso e sa sitisoeng nakong ea ho khaoha ha motlakase ka nako e khuts'oane kapa ha o chencha mehloli ea motlakase.
Ho laola le ho beha leihlo XPON dual band WiFi5 ONU, mekhoa e mengata ea taolo ea fumaneha.Tsena li kenyelletsa Telnet, Web, SNMP (Simple Network Management Protocol), OAM (Ts'ebetso, Tsamaiso, le Tlhokomelo), le TR069.
Qetellong, XPON dual band WiFi5 ONU ke sesebelisoa sa puisano se sebetsang ka mefuta-futa se kopanyang theknoloji ea XPON, lihlopha tse peli tsa WiFi5, le mesebetsi ea ONU.Ka khokahanyo ea eona ea inthanete e potlakileng, lits'ebeletso tse tsoetseng pele tsa lentsoe, le likhetho tse fapaneng tsa taolo, e fana ka tharollo e tšepahalang le e sebetsang bakeng sa basebelisi ba bolulo le likhoebo tse nyane.
