Kwiminyaka yakutshanje, ngophuhliso lweshishini lolwazi lwe-optical kunye neentengiso ezinxulumene noko, i-FTTH (i-Fiber to the Home) ibe sisisombululo somzekelo sophuhliso lwakutshanje lweenethiwekhi zokufikelela. Iyaziqhelanisa nophuhliso lwetekhnoloji kwicandelo le-optical kwaye ihambelana neemfuno zokudluliselwa kwesignali ngesantya esiphezulu, ezinomthamo ophezulu zabasebenzisi kwiinethiwekhi ze-optical. Kwiiprojekthi zokufikelela kwi-FTTH ezinomthamo ophezulu, ukugoba koomatshini kunye namandla okutsalwa kweentambo ze-optical zangaphakathi azisenakwanelisa iimfuno zeentambo ze-optical zangaphakathi ze-FTTH. Ukuphendula imfuno yemarike, iintambo ze-optical fiber eziqinileyo, ezigobileyo ezisezantsi, ziye zavela kwaye zisetyenziswa kakhulu kwiinethiwekhi zokufikelela kwi-FTTH.
Umgama ophezulu wokudluliselwa kwentambo yokuwisa unokufikelela kwiikhilomitha ezingama-70. Nangona kunjalo, ngokubanzi, isigaba sokwakha sigubungela inethiwekhi yomqolo we-fiber optic ukuya endlwini size siyiguqule nge-transceiver ye-optical. Nangona kunjalo, ukuba iprojekthi yekhilomitha enye yenziwa kusetyenziswa intambo yesikhumba, kufuneka ibe yifakelo yangaphandle. Intambo yesikhumba ngokwayo ibuthathaka kakhulu, okwenza kube lula kakhulu ukuyiqhekeza, kwaye ukuqina kwayo akuphezulu kakhulu.
Ngenxa yokuba ithambile kwaye ilula, intambo yedrop isetyenziswa kakhulu kwiinethiwekhi zokufikelela. Igama lesayensi lentambo yedrop yintambo yokungena efana nebhabhathane kwiinethiwekhi zokufikelela; ikwabizwa ngokuba yintambo yebhabhathane ngenxa yesimo sayo. Isetyenziselwa ukwenza iintambo ze-optical kunye neentambo ze-optical ze-figure-eight.
Intambo egqunyiweyo: Yintambo ye-optical engagobiyo enokubonelela nge-bandwidth ephezulu ukuphucula ukusebenza kothumelo lwenethiwekhi; nge-FRP ezimbini ezihambelanayo okanye ukuqinisa isinyithi, intambo ye-optical inokumelana okuhle kokucinezelwa ukukhusela intambo ye-optical; intambo ye-optical inesakhiwo esilula kunye nobunzima obulula, kunye nokusebenza okuhle; inoyilo olulodwa lomsele, kulula ukuyixobula, kwaye kulula ukuyidibanisa.
Ukuba yi-single-mode, inokuba kude, kodwa ukuba iprojekthi yekhilomitha enye yenziwe ngentambo yesikhumba, kufuneka ibe yiprojekthi yangaphandle, ngoko ke kuvakala ngathi intambo yesikhumba ibuthathaka kakhulu, kulula kakhulu ukuyiqhekeza, kwaye ayinawo amandla okuqhuba ixesha elide kangaka.
