Yini i-FTTX ncamashi?

Njengoba sibona isidingo sokwanda okumangazayo kwenani le-bandwidth elilethwa kumakhasimende, ngenxa ye-4K Definition TV TV, izinsizakalo ezifana nezinsizakalo zokwabelana ngokonga, sibona ukwenyuka kwezinsizakalo ze-FTTX noma i-X ". Sonke sithanda izithombe ezisheshayo ze-Intanethi ne-Crystal ecacile kuma-70 inch TV's kanye ne-fiber kuze kube sekhaya - i-FTTth inesibopho sokunethezeka okuncane.

Ngakho-ke kuyini "x"? I- "X" ingamelela izindawo eziningi ezinikezwa ama-Cable TV noma izinsizakalo ze-Broadband, njengekhaya, indawo yokuhlala ehlukahlukene, noma ihhovisi. Lezi zinhlobo zokuphakwa eziletha insiza ngqo kwizakhiwo zamakhasimende futhi lokhu kuvumela ukushesha kokuxhuma ngokushesha kanye nokwethenjwa okuningi kwabathengi. Indawo ehlukile yokuhanjiswa kwakho kungadala ukuguqulwa kwezinto ezahlukahlukene ezizogcina zithinta izinto ozidingayo zephrojekthi yakho. Izici ezingathinta i-fiber to the "x" ukuthunyelwa kungaba yizemvelo, isimo sezulu esihlobene nesimo sezulu, noma vele zidinga ukubhekwa lapho ziklama inethiwekhi. Ezigabeni ezingezansi, sizongena kweminye imishini evame kakhulu esetshenziswa ngaphakathi kwefayibha ekuthumelweni kwe- "X". Kuzoba nokwehluka, izitayela ezahlukene, kanye nabakhiqizi abahlukene, kepha ingxenye enkulu, yonke imishini iyindinganiso enhle ekuthumelweni.

Ihhovisi elikude eliphakathi

Isigxobo noma i-pad ebekwe ehhovisi eliphakathi nendawo noma ukuvalelwa kwenethiwekhi okuhlangene kusebenza njengendawo yesibili ekude yabahlinzeki bezinsizakalo abatholakala esigxotsheni noma emhlabathini. Le ebiyelwe yithuluzi elixhumanisa umhlinzeki wesevisi kuzo zonke ezinye izinto ekuthumelweni kwe-FTTX; Ziqukethe i-terminal yomugqa we-optical, okuyindlela yokugcina yomhlinzeki wesevisi nendawo lapho ukuguqulwa kusuka kwisiginali kagesi ku-Fibre Optic Signals kwenzeka. Zihlomele ngokuphelele isimo somoya, amayunithi okushisa, kanye nokunikezwa kwamandla ukuze ivikelwe ezintweni ezithile. Leli hhovisi eliphakathi nendawo liphakamisa ukuvalelwa kwe-HUB ngentambo yangaphandle yesitshalo fiber optic cable, kungaba izintambo zokungcwaba ezingaphansi komhlaba noma ezingaphansi komhlaba ngokuya ngendawo ephakathi nehhovisi eliphakathi. Lesi ngesinye sezingcezu ezibucayi kakhulu ekufakweni kwe-FTTX, ngoba yilapho konke kuqala.

I-Fibfice Distribution Hub

Le ebiyelwe yenzelwe ukuba yi-interconnect noma indawo yokuhlangana yezintambo ze-fiber optic. Izintambo zingena ebiyelwe kusuka ku-OLT - I-Optical Line terminal bese isibonakaliso sihlukaniswe yi-Optical fiber splitters noma amamojula we-splitter bese kuthunyelwa emuva ngamakhebuli asusiwe athunyelwa emakhaya noma ezakhiweni zamashumi ahlukahlukene. Le yunithi ivumela ukufinyelela okusheshayo kumakhebuli ukuze anikezwe noma alungiswe uma kudingeka. Ungahlola futhi ngaphakathi kwale yunithi ukuqinisekisa ukuthi konke ukuxhumana kusebenza ngokusebenza. Bafika ngosayizi nobukhulu obuhlukahlukene ngokuya ngokufakwa okwenzayo nenombolo yamakhasimende owahlela ekusebenzeni kusuka kuyunithi elilodwa.

Ukuvalelwa kwe-Splice

Ukufakwa kwama-splice kwangaphandle kubekwe ngemuva kwe-fiber distribution hub. Lezi zinhlaka zangaphandle zangaphandle zivumela ikhebula elingasetshenziswanga elingasetshenziswanga ukuba libe nendawo engenakutholwa le micu engatholakala nge-midspan bese ijoyine ikhebula lendlela.

Ama-Splitters

Ama-splitters angomunye wabadlali ababaluleke kakhulu kunoma iyiphi iphrojekthi ye-FTTX. Zisetshenziselwa ukuhlukanisa isiginali engenayo ukuze amakhasimende amaningi anganikezwa nge-fiber eyodwa. Zingabekwa ngaphakathi kwe-fiber Distribution Hubs, noma ezivalweni zangaphandle ze-splice. Ama-splitters avame ukuxhunyaniswa nezixhumi ze-SC / APC ukuze zisebenze kahle. Ama-splitters angaba ne-splits efana ne-1 × 4, 1 × 8, 1 × 32, no-1 × 64, njengoba izinkokhelo ze-FTTX ziba yizinkampani ezivamile futhi ze-Telecom zamukela ubuchwepheshe. Ama-splits amakhulu aya ngokuya evame kakhulu njengoku-1 × 32 noma 1 × 64. Lezi zinhlaka zifanekisela ngempela inani lamakhaya angatholwa yile fiber eyodwa egijima epladi yamehlo.

Amadivayisi we-Network interface (ama-nids)

Amadivayisi we-Network Interface noma amabhokisi e-nid ajwayele ukuthola ngaphandle kwekhaya elilodwa; Azijwayele ukusetshenziswa ekuthulweni kweMDU. Amabhokisi e-NID amabhokisi avalwe ngemvelo abekwe ohlangothini lwekhaya ukuvumela ikhebula le-optical ukuba lingene. Le ntambo imvamisa ikhebula elilinganiswe ngaphandle linqunyelwe ngesixhumi se-SC / APC. I-NID ivame ukuza nokuphuma okuphuma okuphumayo okuvumela ukusetshenziswa kosayizi abaningi bekhebula. Kukhona isikhala ngaphakathi kwebhokisi lamapaneli we-adaptha kanye nemikhono ye-splice. I-NID ayibizi kakhulu, futhi imvamisa incane ngosayizi uma iqhathaniswa nebhokisi leMDU.

Ibhokisi lokusabalalisa yabasebenzisi abaningi

Ibhokisi lokusabalalisa eliningi noma iMDU liwukuvalelwa odongeni olwakhiwe odongeni oluklanyelwe ukubekezelela izimo ezinzima futhi luvumela ukuhlukaniswa kwekhebula elingaphakathi, imvamisa, kungahle futhi ngezindawo ezihlukaniswa yi-SCC kanye nemikhono ye-spli. Lawa mabhokisi atholakala kuwo wonke amahlathi esakhiwo futhi ahlukaniswe abe yimicu eyodwa noma alahle izintambo ezigijimela engxenyeni ngayinye yalolo phasi.

Ibhokisi lokuqothuka

Ibhokisi lokuqothuka livame ukuba namachweba amabili we-fiber avumela ikhebula. Banabaphathi abakhengi abangenayo. Lawa mabhokisi azosetshenziswa ngaphakathi kweyunithi yokuhambisa ama-Multi Dest Tenant, iyunithi ngalinye noma indawo yehhovisi isakhiwo esizoba nebhokisi lokudilizwa elixhunywe ngentambo ebhokisini le-MDU elisesitezi saleyo yunithi. Lezi ngokuvamile zivame ukungabizi futhi zincane kakhulu ifomu lefomu ukuze lifakwe kalula ngaphakathi kweyunithi.

Ekupheleni kosuku, ukuhanjiswa kwe-FTTX akuhambi ndawo, futhi lezi ezinye zezinto esingazibona ekuthumelweni okujwayelekile kwe-FTTX. Kunezinketho eziningi lapho ezingasetshenziswa. Esikhathini esizayo esiseduze, sizobona nje ngokwengeziwe kwalokhu kuhanjiswa kulokho sibona ukwenyuka okwengeziwe kwesidingo se-bandwidth njengentuthuko yezobuchwepheshe. Sethemba ukuthi ukuthunyelwa kwe-FTTX kuzobe sekuza endaweni yakini ukuze futhi ujabulele izinzuzo zokukhuphuka kwejubane lenethiwekhi kanye nezinga eliphakeme lokwethenjwa kwezinsizakalo zakho.
