XPON Technology Overview
XPON ke theknoloji ea phihlello ea Broadband e thehiloeng ho Passive Optical Network (PON).E fihlella phetiso ea data e potlakileng le e nang le bokhoni bo boholo ka phetiso ea fiber e le 'ngoe ea bidirectional.Theknoloji ea XPON e sebelisa mekhoa ea phetisetso e sa sebetseng ea matšoao a optical ho fana ka matšoao a optical ho basebelisi ba bangata, ka hona e hlokomela ho arolelana lisebelisoa tse fokolang tsa marang-rang.
XPON sebopeho sa tsamaiso
Sistimi ea XPON haholo-holo e na le likarolo tse tharo: optical line terminal (OLT), optical network unit (ONU) le passive optical splitter (Splitter).OLT e ofising e bohareng ea opareitara 'me e ikarabella ho fana ka likhokahano tsa mahlakore a marang-rang le ho fetisetsa melaetsa ea data ho marang-rang a marang-rang a holimo joalo ka marang-rang a libaka tsa litoropo.ONU e fumaneha qetellong ea basebelisi, e fa basebelisi monyetla oa ho fumana marang-rang le ho lemoha phetoho le ts'ebetso ea tlhahisoleseding ea data.Li-splitter tsa passive optical li aba lipontšo tsa optical ho tse ngataONUs ho fihlella kgaso ya marangrang.

Theknoloji ea phetisetso ea XPON
XPON e sebelisa theknoloji ea time division multiplexing (TDM) ho finyella phetiso ea data.Ho thekenoloji ea TDM, libaka tse fapaneng tsa nako (Time Slots) li arotsoe lipakeng tsa OLT le ONU ho hlokomela phetiso ea data ka mahlakoreng a mabeli.Ka ho khetheha, theOLTe abela lintlha ho li-ONU tse fapaneng ho latela nako e behiloeng sebakeng se ka holimo, 'me e hasanya data ho li-ONU tsohle tse ka tlase ho noka.ONU e khetha ho amohela kapa ho romela data ho latela boitsebiso ba nako.

XPON data encapsulation le tlhahlobo
Sistimi ea XPON, encapsulation ea data e bolela ts'ebetso ea ho kenyelletsa tlhahisoleseling joalo ka lihlooho le li-trailer ho likarolo tsa data tse fetisoang lipakeng tsa OLT le ONU.Tlhahisoleseding ena e sebelisetsoa ho khetholla mofuta, sebaka le litšoaneleho tse ling tsa yuniti ea data e le hore qetellong ea ho amohela e ka hlalosa le ho sebetsana le data.Phatlalatso ea data ke ts'ebetso eo pheletso e amohelang e khutlisetsang data sebopeho sa eona sa mantlha se ipapisitseng le tlhaiso-leseling ea encapsulation.
Mokhoa oa phetisetso ea data ea XPON
Sistimi ea XPON, ts'ebetso ea phetiso ea data haholo-holo e kenyelletsa mehato e latelang:
1. OLT e kenyelletsa lintlha ka har'a matšoao a optical mme e li romela ho passive optical splitter ka cable ea optical.
2. Phalliso ea passive optical e aba pontšo ea optical ho ONU e lumellanang.
3. Ka mor'a ho amohela letšoao la optical, ONU e etsa phetoho ea optical-to-electric le ho ntša lintlha.
4. ONU e etsa qeto ea hore na data e ea hokae ho latela boitsebiso bo ka har'a encapsulation ea data, 'me e romela boitsebiso ho sesebelisoa se lumellanang kapa mosebedisi.
5. Sesebelisoa se amohelang kapa mosebelisi se sekaseka le ho sebetsana le data ka mor'a ho e amohela.
Mokhoa oa ts'ireletso oa XPON
Mathata a ts'ireletso a tobaneng le XPON haholo-holo a kenyelletsa ho kenella ho seng molaong, litlhaselo tse lonya le ho mamela data.Bakeng sa ho rarolla mathata ana, sistimi ea XPON e sebelisa mekhoa e fapaneng ea ts'ireletso:
1. Mokhoa oa ho netefatsa: Etsa bonnete ba boitsebiso ho ONU ho netefatsa hore basebelisi ba molao feela ba ka fihlella marang-rang.
2. Mochine oa ho ngola ka mokhoa o sireletsehileng: Encrypt data e fetisoang ho thibela data hore e se ke ea mamela kapa ea senyeha.
3. Taolo ea phihlello: Thibela litokelo tsa phihlello tsa basebelisi ho thibela basebelisi ba seng molaong ho sebelisa hampe mehloli ea marang-rang.
4. Ho beha leihlo le ho tšosa: Sheba boemo ba marang-rang ka nako ea sebele, alamo ka nako ha maemo a sa tloaelehang a fumanoa, 'me u nke mehato e ts'oanang ea ts'ireletso.
Tšebeliso ea XPON marang-rang a lapeng
Theknoloji ea XPON e na le menyetla e pharaletseng ea ts'ebeliso ho marang-rang a lapeng.Pele ho tsohle, XPON e ka finyella ho kena Inthaneteng ka lebelo le phahameng ho finyella litlhoko tsa basebelisi ba lehae bakeng sa lebelo la marang-rang;ea bobeli, XPON ha e hloke wiring ea ka hare, e fokotsang litšenyehelo tsa ho kenya le ho hlokomela marang-rang a lapeng;Qetellong, XPON e ka hlokomela ho kopanngoa ha marang-rang a mangata, ho kopanya lithelefono, lithelevishene le lik'homphieutha.Marang-rang a kopantsoe le marang-rang a tšoanang ho nolofatsa tšebeliso le tsamaiso ea basebelisi.
