Sidaynu wada ogsoonahay in danabku yahay dareere ka dhasha koronto atmospheric ah taas oo ka dhalata kharashyo kala duwan oo daruuraha ku soo urura.Natiijadu waa tamar si kedis ah loo sii daayo taasoo keenta holac dhalaalaya oo gaar ah, oo ay ku xigto onkod.
Tusaale ahaan, kaliya ma saameyn doonto dhammaan kanaalada fiber-ka DWDM ee dillaaca gaagaaban, laakiin sidoo kale waxay saameynaysaa jihooyinka gudbinta isku mar marka loo eego cilmi-baarisyo badan.Waxay xitaa dhalin doontaa dab marka ay jiraan dareeraha hillaaca hadda jira.Inkasta oo calaamadaha fiilooyinka fiberku ay yihiin calaamadaha indhaha, inta badan fiilooyinka indhaha ee dibadda ah ee isticmaalaya koodhadhyo la xoojiyay ama fiilooyinka indhaha ee gaashaaman ayaa si sahlan u waxyeelloobi kara iftiinka hoostiisa sababtoo ah lakabka ilaalinta birta ee gudaha fiilada.Sidaa darteed, waxaa muhiim ah in la dhiso nidaamka ilaalinta hillaaca si loo ilaaliyo fiilooyinka indhaha.

Ilaalinta hillaaca ee khadadka fiilada indhaha ee tooska ah: ① Qaabka shaqada ee xafiiska, qaybaha birta ah ee fiilada indhaha waa in lagu xidhaa kala-goysyada, si ay udubdhexaadka xoojinta, lakabka qoyaanka-caddaynta iyo lakabka hubka ee qaybta gudbinta ee indhaha fiilada waxaa lagu hayaa xaalad isku xiran.②Sida ku xusan xeerarka YDJ14-91, lakabka qoyaanka-caddaynta, lakabka hubka iyo xoojinta xudunta u ah isku-xidhka fiilada indhaha waa in la gooyaa koronto, oo aan la isku dhejin, oo ay ku daboolan yihiin dhulka, taas oo ka fogaan karta raasamaal ee hillaaca hadda socda ee fiilada indhaha.Waxay ka fogaan kartaa in hillaaca hadda ka jira dhulka lagu soo geliyo fiilada indhaha ee qalabka dhulka hoostiisa sababtoo ah farqiga u dhexeeya xannibaadda fiilada qulqulka ilaalinta hillaaca iyo qaybta birta ee fiilada indhaha ee dhulka.

Xadhkaha sare ee indhaha: fiilooyinka ganaaxa sare waa in lagu xidhaa koronto oo la dejiyaa 2km kasta.Marka dhulka la dejiyo, si toos ah ayaa loo dejin karaa ama loo dejin karaa iyada oo loo marayo qalab ilaalin qalliin oo ku habboon.Sidan, siliga laalinku wuxuu leeyahay saamaynta ilaalinta ee siliga sare ee dhulka.

Kadib markiifiilada indhahawuxuu galaa sanduuqa terminaalka, sanduuqa terminaalka waa inuu ahaadaa mid dhulka la dhigo.Ka dib marka hadda hillaaca uu galo lakabka birta ee fiilada indhaha, dhulka hoostiisa ee sanduuqa terminaalka ayaa si dhakhso ah u sii deyn kara hillaaca hadda oo wuxuu ka ciyaaraa door difaac ah.Fiilada indhaha si toos ah loo aasay ayaa leh lakabka gaashaanka iyo xudunta la xoojiyay, galka dibaddana waa gal PE (polyethylene), kaas oo si wax ku ool ah uga hortagi kara daxalka iyo qaniinyada jiirka.
