Iyini i-FTTx Impela?

Njengoba sibona isidingo sokwanda okumangazayo kwenani lomkhawulokudonsa olethwa kumakhasimende, ngenxa ye-TV enencazelo ephezulu ye-4K, amasevisi afana ne-YouTube namanye amasevisi okwabelana ngamavidiyo, kanye nezinsizakalo zokwabelana kontanga, sibona ukukhuphuka Ukufakwa kwe-FTTx noma i-Fiber eyengeziwe Ku-“x”.Sonke sithanda i-inthanethi esheshayo nezithombe ezicace bha kuma-TV ethu angu-70 inch kanye ne-Fiber To The Home – i-FTTH inesibopho salokhu kunethezeka okuncane.

Ngakho-ke yini "x"?U-“x” angamela izindawo eziningi lapho i-TV yekhebula noma amasevisi e-broadband elethwa kuzo, njengeKhaya, I-Multi Tenant Dwell, noma i-Office.Lezi zinhlobo zokuthunyelwa eziletha isevisi ngokuqondile emagcekeni ekhasimende futhi lokhu kuvumela isivinini sokuxhuma esisheshayo nokuthembeka okwengeziwe kubathengi.Indawo ehlukile yokuthunyelwa kwakho ingabangela ushintsho lwezinto ezihlukahlukene ezizogcina zithinte izinto ozidingayo kuphrojekthi yakho.Izinto ezingase zibe nomthelela ekusetshenzisweni kwe-Fiber To “x” kungaba ezemvelo, okuhlobene nesimo sezulu, noma ingqalasizinda ekhona kakade okudingeka inakwe lapho kuklanywa inethiwekhi.Ezigabeni ezingezansi, sizodlula kwezinye zezinto ezisetshenziswa kakhulu ezisetshenziswa ngaphakathi kwe-Fiber To the “x” ukusetshenziswa.Kuzoba khona ukuhlukahluka, izitayela ezahlukene, nabakhiqizi abahlukene, kodwa ingxenye enkulu, zonke izisetshenziswa zisezingeni elihle ekusetshenzisweni.

Ihhovisi Eliphakathi Elikude

Ipali noma iphedi efakwe ehhovisi elimaphakathi noma indawo yokuxhumanisa inethiwekhi isebenza njengendawo yesibili ekude yabahlinzeki besevisi abatholakala esigxotsheni noma phansi.Le ndawo ebiyelwe idivayisi exhuma umhlinzeki wesevisi kuzo zonke ezinye izingxenye ekusetshenzisweni kwe-FTTx;aqukethe Itheminali ye-Optical Line, okuyindawo yokugcina yomhlinzeki wesevisi kanye nendawo lapho ukuguqulwa kusuka kumasignali kagesi kuya kumasignali we-fiber optic kwenzeka.Ahlome ngokugcwele isiphephetha-moya, amayunithi okufudumeza, kanye nogesi ukuze avikeleke ezintweni.Leli hhovisi elimaphakathi liphakela izindawo ezivalekile zehabhu ngekhebula le-fiber optic lesitshalo elingaphandle, kungaba ngamakhebula asemoyeni noma angaphansi komhlaba kuye ngendawo yehhovisi elimaphakathi.Lesi ngesinye sezicucu ezibaluleke kakhulu kusitolimende se-FTTx, njengoba kulapho konke kuqala khona.

I-Fiber Distribution Hub

Le ndawo ebiyelwe iklanyelwe ukuthi ibe indawo yokuxhumana noma indawo yokuhlangana yezintambo ze-fiber optic.Amakhebuli angena endaweni ebiyelwe kuyo esuka ku-OLT - Optical Line Terminal bese le signali ihlukaniswa ngama-optical fibre splitters noma amamojula ahlukanisayo bese ibuyiselwa emuva ngamakhebula okudonsa abese ethunyelwa ezindlini noma ezakhiweni eziqashisayo eziningi.Lolu phiko luvumela ukufinyelela ngokushesha ezintamboni ukuze ziseviswe noma zilungiswe uma kudingeka.Ungaphinda uhlole ngaphakathi kwale yunithi ukuze uqinisekise ukuthi konke ukuxhumana kuyasebenza.Ziza ngosayizi abahlukahlukene kanye nokwakheka kuye ngokufaka okwenzayo kanye nenani lamakhasimende ohlela ukuwahlinzeka ngeyunithi eyodwa.

Ama-Splice Enclosures

Izivalo ze-splice zangaphandle zibekwe ngemuva kwehabhu lokusabalalisa i-fiber.Lezi zivalo ze-splice zangaphandle zivumela ikhebuli yangaphandle engasetshenzisiwe ukuthi ibe nendawo yokungenzi lutho lapho le micu ingafinyelelwa khona nge-midspan bese ihlanganiswa nekhebuli yokudonsa.

Ama-Splitters

Ama-Splitters angomunye wabadlali ababaluleke kakhulu kunoma iyiphi iphrojekthi ye-FTTx.Asetshenziselwa ukuhlukanisa isignali engenayo ukuze amakhasimende amaningi akwazi ukuseviswa ngefayibha eyodwa.Angafakwa ngaphakathi kwamahabhu okusabalalisa i-fiber, noma ezindaweni ezivalekile ze-splice.Izihlukanisi ngokuvamile zixhunywa nezixhumi ze-SC/APC ukuze zisebenze kahle.Izihlukanisi zingaba nokuhlukana okufana no-1×4, 1×8, 1×16, 1×32, kanye no-1×64, njengoba ukuthunyelwa kwe-FTTx kuya kuvame kakhulu futhi nezinkampani eziningi ze-telecom zamukela ubuchwepheshe.Ukuhlukaniswa okukhulu kuya ngokuya kuvame kakhulu njengokuthi 1×32 noma 1×64.Lezi zihlukaniso zifanekisela ngempela inani lamakhaya elingafinyelelwa yilo mucu owodwa ogijima ku-splitter ye-optical.

I-Network Interface Devices (NIDs)

Amadivayisi e-Network Interface noma amabhokisi e-NID ngokuvamile atholakala ngaphandle kwekhaya elilodwa;awavamisile ukusetshenziswa ekusetshenzisweni kwe-MDU.Ama-NID amabhokisi avalwe ngokwemvelo abekwe eceleni kwekhaya ukuze kungene intambo yokubona.Le khebula ivamise ukuba ikhebula lokuwisa elilinganiselwe ngaphandle elinqanyulwe ngesixhumi se-SC/APC.Ama-NID ngokuvamile afika nama-outlet grommets avumela ukusetshenziswa kosayizi abaningi bekhebula.Kunesikhala ngaphakathi kwebhokisi samaphaneli e-adaptha nemikhono ehlanganisayo.Ama-NID awabizi, futhi ngokuvamile mancane ngosayizi uma kuqhathaniswa nebhokisi le-MDU.

Ibhokisi Lokusabalalisa Abaqashi Abaningi

Ibhokisi lokusabalalisa abaqashi abaningi noma ibhokisi le-MDU liyindawo ebiyelwe odongeni eklanyelwe ukumelana nezimo ezinzima futhi ivumela imicu eminingi engenayo, ngokuvamile esesimweni sekhebula lokusabalalisa langaphakathi/ngaphandle, futhi lingafaka izihlukanisi ezibonakalayo ezinqanyulwe nge-SC. /Izixhumi ze-APC nemikhono ehlanganisayo.Lawa mabhokisi atholakala kuzo zonke izitezi zesakhiwo futhi ahlukaniswa abe imicu eyodwa noma izintambo zokuwisa ezigijima kuyunithi ngayinye kuleso sitezi.

Ibhokisi Lokuklama

Ibhokisi lokuklama ngokuvamile linezimbobo ezimbili zefayibha ezivumela ikhebuli.Banezibambi zemikhono ezakhelwe ngaphakathi.Lawa mabhokisi azosetshenziswa endaweni yokusabalalisa abaqashi abaningi, iyunithi ngayinye noma indawo yehhovisi isakhiwo esinaso sizoba nebhokisi lokuklama elixhunywe ngekhebula eBhokisini le-MDU elibekwe phansi kuleyo yunithi.Lokhu kuvame ukungabizi kakhulu futhi kuncane okuyifomu ukuze kubekwe kalula phakathi kweyunithi.

Ekupheleni kosuku, ukuthunyelwa kwe-FTTx akuyi ndawo, futhi lezi ezinye zezinto esingazibona ekusetshenzisweni okujwayelekile kwe-FTTx.Kunezinketho eziningi laphaya ezingase zisetshenziswe.Esikhathini esizayo esiseduze, sizobona kuphela ukwanda kwalokhu kuthunyelwa ngoba sibona ukwanda okwengeziwe kwesidingo somkhawulokudonsa njengoba ubuchwepheshe buthuthuka.Ngethemba, ukuthunyelwa kwe-FTTx kuzofika endaweni yangakini ukuze ukwazi futhi ukujabulela izinzuzo zokukhuphula isivinini senethiwekhi kanye nezinga eliphezulu lokwethembeka kumasevisi akho.
