Waa maxay FTTx?
FTTx waa "Fiber To The x" waana ereyga guud ee helitaanka fiber ee isgaarsiinta fiber optic.x waxay ka dhigan tahay halka loo socdo khadka fiber-ka.Sida x = H (Fiber to the Home), x = O (Fiber to the Office), x = B (Fiber to the House).Farsamada FTTx waxay u dhaxaysaa qalabka xafiiska dhexe ee qolka isgaadhsiinta gobolka ilaa qalabka adeegsadaha, oo ay ku jiraan terminaalka khadka indhaha (OLT), unugga shabakada indhaha (ONU), terminaalka shabakada indhaha (ONT).
Marka loo eego goobta ONU ee dhamaadka isticmaale ee unugga shabakada indhaha, waxaa jira noocyo badan oo FTTx ah, kuwaas oo loo qaybin karo fiber ilaa sanduuqa beddelka (FTTCab), fiber ilaa wadada dhinaceeda (FTTC), fiber ilaa dhismaha (FTTB), fiber to the home (FTTH), fiber To the office (FTTO) iyo foomamka adeegga kale.Hawlwadeenka Maraykanka Verizon wuxuu u jeedaa FTTB iyo FTTH inay yihiin fiber-ka dhismaha (FTTP).
FTTCab(Fiber ilaa Golaha Wasiirada)
Fiilada dhaqameedka waxaa lagu beddelaa fiber optic ah.ONU waxa la dhigayaa sanduuqa isgoyska.ONU-da hoose waxay isticmaashaa silig naxaas ah ama warbaahin kale si ay ugu xidho isticmaalaha.
FTTC(Fiber To the Curb)
Rakibaadda iyo isticmaalka xadhkaha indhaha ee laga soo bilaabo xafiiska dhexe ilaa waddooyinka dhinacyadeeda oo kun fiit u jira guryo ama xafiisyo.Guud ahaan, isku xirka gudbinta balaadhtanka ee suurtogalka ah oo aad ugu dhow isticmaalaha ayaa marka hore la dhigaa.Marka ay jirto baahi loo qabo adeegyada xayndaabyada, fiberku si dhakhso ah ayaa loo horseedi karaa isticmaalayaasha, fiber-ka ayaa lagu gaari karaa guriga.
FTTB(Fiber ilaa Dhismaha)
Waa habka marinka ballaadhan ee ku salaysan tignoolajiyada shabakadda fiber indhaha ee la hagaajiyay.Waxay u isticmaashaa fiber-ka dhismaha iyo fiilada isku-xidhka ee guriga si ay u gaadho marinka ballaadhan ee isticmaalaha.Guud ahaan, marin u heelan oo khadka ah ayaa la isticmaalaa, kaas oo fudud in la rakibo oo bixin kara ugu badnaan kor iyo heerka hoose ee 10Mbps (gaar ah).
FTTH(Fiber To The Home)
TTH waxaa loola jeedaa rakibaadda unugga shabakadda indhaha (ONU) ee isticmaale guriga ama isticmaale shirkadeed.Waa nooca arjiga shabakadda gelitaanka indhaha ee ugu dhow isticmaalaha marka laga reebo FTTD (fiber optical to desktop) ee taxanaha marinka indhaha.Tiknoolajiyada PON waxay noqotay goob kulul oo ay wadaagaan hawl-wadeennada ballaadhan ee caalamiga ah waxaana loo arkaa inay tahay mid ka mid ah xalalka farsamo ee ugu wanaagsan si loo gaaro FTTH.
FTTP(Fiber To the Premise)
FTTP waa erey Waqooyiga Ameerika.Waxaa ka mid ah FTTB, FTTC, iyo FTTH si cidhiidhi ah, oo waxay ku fidisaa fiilooyinka fiber indhaha guryaha ama shirkadaha.
