XPON Technology Uhlolojikelele
I-XPON ubuchwepheshe bokufinyelela ku-broadband obusekelwe ku-Passive Optical Network (PON). Ifinyelela ukudluliswa kwedatha yesivinini esikhulu kanye namandla amakhulu ngokudluliswa kwe-fiber eyodwa kabilirectional. Ubuchwepheshe be-XPON busebenzisa izici zokudlulisa ezingashintshiwe zamasiginali okukhanya ukuze kusabalalise amasiginali okubona kubasebenzisi abaningi, ngaleyo ndlela ibone ukwabelana kwezinsiza zenethiwekhi ezinomkhawulo.
Isakhiwo sesistimu ye-XPO
Uhlelo lwe-XPON ngokuyinhloko luqukethe izingxenye ezintathu: i-optical line terminal (OLT), i-optical network unit (ONU) kanye ne-passive optical splitter (Splitter). I-OLT itholakala ehhovisi elimaphakathi lo-opharetha futhi inomthwalo wemfanelo wokuhlinzeka ngendawo yokuxhumana eseceleni kwenethiwekhi kanye nokudlulisa imifudlana yedatha kumanethiwekhi asezingeni eliphezulu njengamanethiwekhi endawo yedolobha elikhulu. I-ONU itholakala ekugcineni komsebenzisi, inikeza abasebenzisi ukufinyelela kwenethiwekhi nokuqaphela ukuguqulwa nokucutshungulwa kolwazi lwedatha. Izihlukanisi ze-Passive Optical zisakaza amasiginali okukhanya kokuningiI-ONUs ukuzuza ukusabalala kwenethiwekhi.

Ubuchwepheshe bokudlulisa i-XPON
I-XPON isebenzisa ubuchwepheshe be-time division multiplexing (TDM) ukuze kuzuzwe ukudluliswa kwedatha. Kubuchwepheshe be-TDM, izikhala zesikhathi ezihlukene (Izikhala Zesikhathi) zihlukaniswa phakathi kwe-OLT ne-ONU ukuze kubonwe ukudluliswa kwedatha okukabili. Ngokuqondile, i-OLTyabela idatha kuma-ONU ahlukene ngokwezikhala zesikhathi endaweni ekhuphuka nomfula, futhi isakaza idatha kuwo wonke ama-ONU abheke ezansi nomfula. I-ONU ikhetha ukwamukela noma ukuthumela idatha ngokuya ngokuhlonzwa kwesikhala sesikhathi.

XPON idatha encapsulation kanye nokuhlaziywa
Kusistimu ye-XPON, ukufakwa kwedatha kubhekisela kunqubo yokwengeza ulwazi olufana nezihloko nama-trailer kumayunithi edatha adluliswa phakathi kwe-OLT ne-ONU. Lolu lwazi lusetshenziselwa ukukhomba uhlobo, indawo kanye nezinye izibaluli zeyunithi yedatha ukuze indawo eyamukelayo ihlaziye futhi icubungule idatha. Ukuhlaziya idatha kuyinqubo lapho isiphetho sokwamukela sibuyisela idatha kufomethi yayo yoqobo ngokusekelwe olwazini lwe-encapsulation.
Inqubo yokudlulisa idatha ye-XPO
Kuhlelo lwe-XPON, inqubo yokudlulisa idatha ikakhulukazi ihlanganisa lezi zinyathelo ezilandelayo:
1. I-OLT ihlanganisa idatha ibe amasignali optical futhi iwathumele kusihlukanisi se-passive optical ngentambo yokubona.
2. Isihlukanisi se-passive optical sisabalalisa isignali yokubona ku-ONU ehambisanayo.
3. Ngemva kokuthola isignali ye-optical, i-ONU yenza ukuguqulwa kwe-optical-to-electrical futhi ikhiphe idatha.
4. I-ONU inquma indawo yedatha ngokusekelwe kulwazi oluku-encapsulation yedatha, futhi ithumela idatha kudivayisi ehambisanayo noma umsebenzisi.
5. Idivayisi eyamukelayo noma umsebenzisi uhlaziya futhi acubungule idatha ngemva kokuyithola.
Indlela yokuphepha ye-XPO
Izinkinga zokuphepha ezibhekene ne-XPON ikakhulukazi zihlanganisa ukungena okungekho emthethweni, ukuhlasela okunonya kanye nokulalela idatha. Ukuze kuxazululwe lezi zinkinga, uhlelo lwe-XPON lusebenzisa izindlela zokuphepha ezihlukahlukene:
1. Indlela yokuqinisekisa: Yenza ukufakazela ubuwena ku-ONU ukuze uqinisekise ukuthi abasebenzisi abasemthethweni kuphela abangafinyelela inethiwekhi.
2. Indlela yokubethela: Bethela idatha edluliswayo ukuze uvikele idatha ukuthi ingavinjelwa noma iphazanyiswe.
3. Ukulawula ukufinyelela: Khawulela amalungelo abasebenzisi okufinyelela ukuze uvimbele abasebenzisi abangekho emthethweni ekusebenziseni kabi izinsiza zenethiwekhi.
4. Ukuqapha nokwethusa: Gada isimo senethiwekhi ngesikhathi sangempela, i-alamu ngesikhathi lapho kutholakala izimo ezingavamile, futhi uthathe izinyathelo zokuphepha ezihambisanayo.
Ukusetshenziswa kwe-XPON kunethiwekhi yasekhaya
Ubuchwepheshe be-XPON bunamathemba okusebenza abanzi kumanethiwekhi asekhaya. Okokuqala, i-XPON ingakwazi ukufinyelela ku-inthanethi ngesivinini esiphezulu ukuze ihlangabezane nezidingo zabasebenzisi basekhaya ngesivinini senethiwekhi; okwesibili, i-XPON ayidingi izintambo zasendlini, ezinciphisa ukufakwa nokugcinwa kwezindleko zamanethiwekhi asekhaya; ekugcineni, i-XPON ingakwazi ukubona ukuhlanganiswa kwamanethiwekhi amaningi, ukuhlanganisa izingcingo, ama-TV namakhompyutha. Inethiwekhi ihlanganiswe kunethiwekhi efanayo ukuze kube lula ukusetshenziswa nokuphathwa komsebenzisi.
