Xadhkaha Fiber Optic waxaa loo isticmaalaa in laga sameeyo xadhkaha balastar ee qalabka ilaa isku xirka fiilooyinka fiber optic.Waxaa jira lakab difaac oo dhumuc weyn, kaas oo guud ahaan loo isticmaalo isku xirka u dhexeeya transceiver indhaha iyo sanduuqa terminalka.jumpers fiber indhaha (sidoo kale loo yaqaan xirayaasha fiber optic) tixraac xirayaasha xirayaasha ku rakiban labada daraf ee fiilada indhaha si loo xaqiijiyo isku xirka firfircoon ee wadada indhaha;furayaasha ku yaal hal daraf ayaa loo yaqaan pigtails.Xadhkaha Fiber patch-ka (Optical Fiber Patch Cord/Cable) waxay la mid yihiin fiilooyinka coaxial, laakiin aan lahayn gaashaanka mesh.Xaruntu waa udub dhexaadka galaaska ee uu iftiinku ku socdo.Fiber qaab-dhismeedka kala duwan leh, dhexroorka xudunta ayaa ah 50 μm ilaa 65 μm, kaas oo qiyaastii ah dhumucda timaha bini'aadamka.

Jumpers-ka fiber-ka indhaha ayaa inta badan loo qaybiyaa laba qaybood:

jumpers fiber indhaha waxaa loo qaybin karaa silikoon-ku salaysan caadiga ah fiber indhaha hal-mode iyo jumpers multi-mode sida ku xusan warbaahinta kala duwan, iyo boodada fiber indhaha kale sida caag ah sida dhexdhexaad ah gudbinta;marka loo eego qaab dhismeedka xidhiidhiyaha, waxa loo qaybin karaa: FC Jumper, SC jumper, ST jumper, LC jumper, MTRJ jumper, MPO jumper, MU jumper, SMA jumper, FDDI jumper, E2000 jumper, DIN4 jumper, D4 jumper, iwm qaab.Kuwa boodboodka ah ee caanka ah waxaa sidoo kale loo qaybin karaa FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST, iwm.
