Ukuvula Ukuxhumana Kwesizukulwane Esilandelayo
/ISIXAZULULO/
Amandla ezixazululo ze-XPON ONU
Ezweni lanamuhla elixhumene kakhulu, i-inthanethi ethembekile neshesha kakhulu ayiseyona into yokunethezeka—iyadingeka. Okuhamba phambili ekwenzeni lolu shintsho lwedijithali lusebenzeI-Oyi international., Ltd., inkampani yezintambo ze-fiber optic ephayona eseShenzhen. Selokhu yasungulwa ngo-2006, i-OYI izinikezele ekuletheni imikhiqizo nezixazululo ze-fiber ezisezingeni lomhlaba emhlabeni wonke. Njengoba inethimba eliqinile le-R&D lochwepheshe abangaphezu kuka-20, inkampani iqhuba njalo ukusungula izinto ezintsha kubuchwepheshe be-fiber. Imikhiqizo yayo, ethunyelwa emazweni angu-143 futhi ethenjwa ngabalingani besikhathi eside abangu-268, isetshenziswa kabanzi kuukuxhumana ngocingo, izikhungo zedatha, i-cable TV, kanye nezinhlelo zokusebenza zezimboni. Ukuzibophezela kwe-OYI ekhwalithini nasekusebenzeni kahle kwakha umgogodla wezixazululo zokuxhumana ezithuthukisiwe njenge-XPON ONU.
Iyini i-XPON ONU Solution?
I-XPON, noma i-10-Gigabit Capable Passive Optical Network, imelela igxathu elikhulu ku-inthanethi.ubuchwepheshe be-fiber optic. I-AnIyunithi Yenethiwekhi Yokukhanya (i-ONU)iyithuluzi elibalulekile kulokhu kusethwa, elisebenza njengendawo yokugcina kunethiwekhi ye-fiber-to-the-premises (FTTP). Isixazululo se-XPON ONU sihlanganisa idatha esheshayo, izwi, kanye nezinsizakalo zevidiyo kumugqa owodwa we-fiber, sihlinzeka ngengqalasizinda esebenza kahle futhi evikela ikusasa. Kodwa ngale kwencazelo yobuchwepheshe, okubaluleke ngempela inani elibonakalayo elililetha kubasebenzisi.
Ukuxazulula Izinkinga Zangempela
Inselele eyinhloko ekuxhumaneni kwenethiwekhi yesimanje ukuletha i-bandwidth enkulu ukusekela izinhlelo zokusebenza ezisebenzisa idatha eningi—kusukela ekusakazeni kwe-4K kanye nokudlala ku-inthanethi kuya kumasevisi efu kanye namadivayisi e-IoT.amanethiwekhi ivame ukwehluleka, ihlushwa ukulinganiselwa kwesivinini, ukuwohloka kwesignali, kanye nezindleko zokulungisa eziphezulu. Isixazululo se-XPON ONU sibhekana ngqo nalezi zinkinga ngokusebenzisa ama-fiber optic ahlanzekile, siqinisekisa i-inthanethi enesivinini esiphezulu esilinganayo—okusho ukuthi isivinini sokulayisha nokulanda singafinyelela ku-10 Gbps. Lokhu kuqeda izithiyo, kunciphisa ukubambezeleka, futhi kunikeza ulwazi lomsebenzisi olungenamthungo ngisho nangesikhathi samahora okusetshenziswa okuphezulu.
Izicelo Eziyinhloko kanye Nokusetshenziswa
Lesi sixazululo sisebenziseka ngezindlela eziningi kakhulu, okwenza sifanelekele izindawo ezahlukene. Ezindaweni zokuhlala, senza kube lulaI-Fiber-to-the-Home (FTTH)ukuxhumana, ukusekelaamakhaya ahlakaniphilekanye nezinhlelo zokuzijabulisa. Kwamabhizinisi, inikeza i-bandwidth ethembekile yemihlangano yevidiyo, ukudluliselwa kwedatha enkulu, kanye nezinhlelo zokusebenza ezisingathiwe. Izinkampani zokuxhumana zisebenzisa i-XPON ONU ukuthuthukisa okunikezwayo kwezinsizakalo zazo, kuyilapho amapaki ezimboni namakhampasi eyisebenzisela ukuxhumana kwangaphakathi okuqinile. Empeleni, noma kuphi lapho i-inthanethi esheshayo nezinzile ibalulekile,I-XPON ONUinikeza impendulo enokukhuliswa.
Indlela Esebenza Ngayo: Ukulula Kokuklama
Isimiso esiyisisekelo sobuchwepheshe be-XPON sinobuhle. Sisebenzisa i-topology ye-point-to-multipoint, lapho i-single optical line terminal (OLT) ekugcineni komhlinzeki wesevisi ixhumana nama-ONU amaningi endaweni yamakhasimende. Idatha idluliselwa ngamasignali okukhanya phezu kwefayibha eyodwa, ehlukaniswa ibe yimigqa eminingi kusetshenziswa ama-splitter angasebenzi. Lokhu "ukungasebenzi" kusho ukuthi izingxenye zenethiwekhi phakathi kwe-OLT ne-ONU azidingi amandla, okukhulisa kakhulu ukuthembeka nokunciphisa izindleko zokusebenza. Idivayisi ye-ONU ngokwayo iguqula lezi zimpawu zokukhanya zibe amasignali kagesi angasetshenziswa amakhompyutha, ama-router, kanye namafoni.
Inqubo Yokufaka Elula
Ukufaka isixazululo se-XPON ONU kulula, ikakhulukazi uma kuhlanganiswe nezingxenye ezihambisanayo. Inqubo iqala ngokubeka ikhebula le-fiber optic—njenge-Drop Cable noma i-Outdoor Drop Cable—kusuka endaweni eyinhloko yokusabalalisa. Le khebula ixhumeka kwi-Optical Distribution Box noma i-Fiber Termination Box esakhiweni. Ukusuka lapho, i-Drop Fibre Cable isebenza kuyunithi ngayinye, iphele kwi-Fiber Patch Box noma i-Optical Termination point. Idivayisi ye-ONU ibe isixhunywa, ngokuvamile eceleni kwe-Splitter njenge-FTTH Fiber Splitter, ukuphatha ukuxhumana okuningi. Izesekeli ezibalulekile njenge-Cable Fittings, i-Anchoring Clamp, kanye ne-Hardware ADSS ziqinisekisa ukuthi ziphephile futhi zihlala isikhathi eside.ukufakwa kwangaphandle, kuyilapho amabhokisi okuvala i-Fiber kanye namabhokisi okushintsha i-Fiber evikela iziphambano ezibalulekile.
Kulabo abathuthukisa ingqalasizinda yabo yenethiwekhi, i-OYI inikeza imikhiqizo ehlukahlukene ethembekile ehambisana ne-ecosystem ye-XPON ONU. Lokhu kufaka phakathi i-OPGW Fiber Cable yemigqa eqinile ye-overhead, i-Central Tube Cable yezinhlelo zokusebenza ezinabantu abaningi, kanye nezesekeli ze-Fiber Drop ukuze kube lula ukuzisebenzisa. Umkhiqizo ngamunye wenzelwe ukusebenza kahle ngaphakathi kwesixazululo, ukuqinisekisa ukusebenza kusukela ekuqaleni kuze kube sekupheleni.
Isixazululo se-XPON ONU singaphezu nje kokuthuthukiswa kobuchwepheshe; siyindlela yokutshala imali ehlelekile ekuxhumaneni okulungele ikusasa. Ngokuxazulula izinkinga eziyinhloko ze-bandwidth, ukuthembeka, kanye nezindleko, sinika amandla abahlinzeki bezinsizakalo, amabhizinisi, kanye nabanini bezindlu ngokufanayo. Isekelwa ulwazi olubanzi lwe-OYI kanye nemikhiqizo yokusekela esezingeni eliphezulu—kusukela ku-ONU Splitters kuya ku-Amabhokisi Okuvala Ifayibha—lesi sixazululo simelela indinganiso yegolide kwezokuxhumana kwe-optical. Njengoba isidingo sedatha siqhubeka nokukhula, ukwamukela i-XPON ONU akuyona nje inketho kodwa kuyisidingo sokuhlala uxhumekile enkathini yedijithali.
