Eminyakeni yamuva nje, ngokuthuthukiswa komkhakha wolwazi lwe-optical kanye nokukhushulwa okuhlobene, i-FTTH (i-Fiber to the Home) ibe yisisombululo esiyisibonelo sokuthuthukiswa kwamuva kwamanethiwekhi okufinyelela. Ivumelana nentuthuko yezobuchwepheshe emkhakheni we-optical futhi ihambisana nezidingo zokudlulisa isignali esheshayo, enamandla aphezulu zabasebenzisi kumanethiwekhi optical. Kumaphrojekthi okufinyelela e-FTTH anomthamo ophezulu, ukugoba komshini kanye namandla okudonsa ezintambo ze-optical zangaphakathi ezivamile akusakwazi ukuhlangabezana nezidingo zezintambo ze-FTTH zangaphakathi. Ngokuphendula isidingo semakethe, izintambo ze-optical fiber eziqinile, ezigobile kancane, ezimbozwe ngesikhumba ziye zavela futhi zisetshenziswa kabanzi kumanethiwekhi okufinyelela e-FTTH.
Ibanga eliphezulu lokudlulisa lekhebula lokudonsa lingafinyelela amakhilomitha angu-70. Kodwa-ke, ngokuvamile, isigaba sokwakha simboza inethiwekhi yomgogodla we-fiber optic kuze kufike endlini bese siyihlukanisa nge-transceiver ye-optical. Kodwa-ke, uma kwenziwa iphrojekthi yekhilomitha elilodwa kusetshenziswa ikhebula elimbozwe ngesikhumba, kumele kube ukufakwa kwangaphandle. Ikhebula elimbozwe ngesikhumba ngokwalo libuthakathaka kakhulu, okwenza kube lula kakhulu ukuliphula, futhi ukuqina kwalo akuphakeme kakhulu.
Ngenxa yobumnene bayo nokukhanya kwayo, ikhebula lokudonsa lisetshenziswa kabanzi kumanethiwekhi okufinyelela. Igama lesayensi lekhebula lokudonsa yikhebula lokungena elinomumo webhabhathane lamanethiwekhi okufinyelela; libizwa nangokuthi ikhebula lobhabhathane ngenxa yesimo salo. Lisetshenziselwa ukwakha amakhebula okukhanya kanye namakhebula okukhanya angu-figure-eight.
Ikhebula elimboziwe: Liyi-fiber optical engagobi enganikeza i-bandwidth ephezulu ukuthuthukisa ukusebenza kokudlulisa kwenethiwekhi; nge-FRP ezimbili noma ukuqinisa kwensimbi okuhambisanayo, ikhebula optical linokumelana okuhle kokucindezela ukuvikela i-fiber optical; ikhebula optical linesakhiwo esilula nesisindo esincane, kanye nokusebenza okuhle; linomklamo oyingqayizivele womsele, okulula ukuwukhipha, futhi kungaba lula ukuwuhlanganisa.
Uma kuyimodi eyodwa, ingaba kude, kodwa uma iphrojekthi yekhilomitha elilodwa yenziwe ngekhebula lesikhumba, kumele kube iphrojekthi yangaphandle, ngakho-ke kuzwakala sengathi ikhebula lesikhumba libuthakathaka kakhulu, kulula kakhulu ukuliphula, futhi alinamandla okugijima isikhathi eside kangaka.
