XPON Technology mwachidule
XPON ndi ukadaulo wofikira ku Broadband yozikidwa pa Passive Optical Network (PON).Imakwaniritsa kufalitsa kwachangu komanso kokulirapo kwa data kudzera munjira imodzi ya fiber bidirectional transmission.Ukadaulo wa XPON umagwiritsa ntchito mawonekedwe osasunthika a ma siginecha owoneka kuti agawire ma siginecha owoneka kwa ogwiritsa ntchito angapo, potero kuzindikira kugawana zinthu zochepa zama network.
XPON dongosolo dongosolo
Makina a XPON makamaka amakhala ndi magawo atatu: optical line terminal (OLT), optical network unit (ONU) ndi passive optical splitter (Splitter).OLT ili ku ofesi yapakati ya opareshoni ndipo ili ndi udindo wopereka zolumikizira zam'mbali za netiweki ndikutumiza ma data kuma netiweki apamwamba monga ma netiweki amadera akumidzi.ONU ili pamapeto ogwiritsira ntchito, kupatsa ogwiritsa ntchito mwayi wopezera maukonde ndikuzindikira kutembenuka ndi kukonza chidziwitso cha data.Zogawanitsa za Passive Optical zimagawa ma siginecha owoneka ngati angapoONUs kukwaniritsa kufalikira kwa netiweki.

Ukadaulo wopatsirana wa XPON
XPON imagwiritsa ntchito ukadaulo wa time division multiplexing (TDM) kuti ikwaniritse kutumiza kwa data.Muukadaulo wa TDM, mipata yosiyana ya nthawi (Time Slots) amagawidwa pakati pa OLT ndi ONU kuti azindikire kufalikira kwa data kawiri.Makamaka, aOLTamagawa deta ku ma ONU osiyanasiyana malinga ndi nthawi yolowera kumtunda, ndikuwulutsa deta ku ma ONU onse kumunsi kwa mtsinje.ONU imasankha kulandira kapena kutumiza deta molingana ndi chizindikiritso cha nthawi.

XPON data encapsulation ndi kusanthula
Mu dongosolo la XPON, kuyika kwa data kumatanthawuza njira yowonjezerera zambiri monga mitu ndi ma trailer kumagawo a data omwe amafalitsidwa pakati pa OLT ndi ONU.Chidziwitsochi chimagwiritsidwa ntchito kuzindikiritsa mtundu, kopita ndi zikhumbo zina za data unit kotero kuti mapeto olandira akhoza kuwerengera ndi kukonza deta.Kuyika kwa data ndi njira yomwe mapeto olandirira amabwezeretsa deta ku mtundu wake woyambirira kutengera chidziwitso cha encapsulation.
Njira yotumizira deta ya XPON
Mu dongosolo la XPON, njira yotumizira deta imaphatikizapo izi:
1. OLT imayika deta mu zizindikiro za kuwala ndikuzitumiza ku passive optical splitter kudzera mu chingwe cha kuwala.
2. The passive optical splitter imagawira chizindikiro cha kuwala kwa ONU yofanana.
3. Pambuyo polandira chizindikiro cha kuwala, ONU imapanga kutembenuka kwa optical-to-electrical ndikuchotsa deta.
4. ONU imasankha kopita kwa deta malinga ndi zomwe zili mu encapsulation ya deta, ndikutumiza deta ku chipangizo chogwirizana kapena wogwiritsa ntchito.
5. Chipangizo cholandira kapena wogwiritsa ntchito amasanthula ndikusintha deta atalandira.
Njira yachitetezo cha XPON
Mavuto achitetezo omwe XPON amakumana nawo makamaka akuphatikizira kulowerera mosaloledwa, kuwukira koyipa komanso kuyang'ana ma data.Kuti athetse mavutowa, XPON imagwiritsa ntchito njira zosiyanasiyana zotetezera:
1. Njira yotsimikizira: Chitani zovomerezeka pa ONU kuti muwonetsetse kuti ogwiritsa ntchito ovomerezeka okha ndi omwe angathe kupeza intaneti.
2. Njira yobisalira: Sungani deta yotumizidwa kuti musamve kapena kusokonezedwa.
3. Kuwongolera kolowera: Kuletsa ufulu wa ogwiritsa ntchito kuti aletse ogwiritsa ntchito osaloledwa kugwiritsa ntchito molakwika maukonde.
4. Kuyang'anira ndi kuchititsa mantha: Yang'anirani mawonekedwe a netiweki munthawi yeniyeni, alamu panthawi yomwe zinthu zachilendo zipezeka, ndipo tsatirani njira zotetezera.
Kugwiritsa ntchito XPON pa intaneti yakunyumba
Ukadaulo wa XPON uli ndi mwayi wogwiritsa ntchito kwambiri pama network apanyumba.Choyamba, XPON ikhoza kukwaniritsa intaneti yothamanga kwambiri kuti ikwaniritse zosowa za ogwiritsa ntchito kunyumba chifukwa cha liwiro la intaneti;chachiwiri, XPON sikutanthauza mawaya m'nyumba, amene amachepetsa unsembe ndi kukonza nyumba Intaneti;Pomaliza, XPON imatha kuzindikira kuphatikiza kwa maukonde angapo, kuphatikiza mafoni, ma TV ndi makompyuta.Ma network amaphatikizidwa mu netiweki yomweyo kuti athandizire kugwiritsa ntchito ndi kasamalidwe ka ogwiritsa ntchito.
