Fiber indhahaisa light conduction Tool kaas oo isticmaala mabda'a wadarta iftiinka iftiinka ee fiber ka samaysan dhalo ama caag.
Fiber aragga indhaha ayaa guud ahaan loo qaybiyaa saddex lakab: xudunta, daboolka iyo dahaarka.
Xudunta fiber indhaha iyo cladding waxay ka kooban yihiin galaas of tusmooyinka refractive kala duwan, oo leh xudunta dhalooyinka refractive sare (germanium-doped Silicon dioxide) ee xarunta iyo index hoose ee silikon cladding (silicon dioxide saafi ah) ee dhexe. Iftiinka waxaa lagu toogtaa fiber-ka xagal dhacdo gaar ah, qiiqa buuxana wuxuu ka dhacaa inta u dhaxaysa fiber-ka iyo xijaabka (sababtoo ah index refractive of cladding ayaa waxyar ka hooseeya xudunta), si uu ugu faafo fiberka. Shaqada ugu weyn ee lakabka daboolka ayaa ah in laga ilaaliyo fiber-ka dhaawaca dibadda, isla markaana kordhiya dabacsanaanta fiber-ka. Sida hore loo soo sheegay, xudunta iyo daboolku waxay ka samaysan yihiin muraayado, kuwaas oo aan la leexin karin oo aan jilicsanayn, isticmaalka lakabka daboolka ayaa ilaaliya oo kordhiya nolosha fiber-ka.
Kor ku xusan waa "qaab-dhismeedka fiber" ay keeneen HDV PhoelektaroonikTechnology LTD.Shirkadeena waa qalab shabakadeed oo khaas ah sida soosaarayaasha wax soo saarka ugu weyn, qalabka shabakada ee laxiriira waxay dabooshaa taxanaha OLT, taxanaha ONU, taxanaha beddelka, taxanaha moduleka indhaha iyo wixii la mid ah, ku soo dhawoow inaad fahamto.
