Fiber optic jumper (tseem hu ua fiber optic connector) yog hais txog kev teeb tsa ntawm cov txuas txuas ntawm ob qho kawg ntawm ib qho khoom siv kho qhov muag kom ua tiav kev sib txuas ntawm txoj kev kho qhov muag; Yog hais tias ib qho kawg yog nruab nrog lub ntsaws, nws yog hu ua tus Tsov tus tw fiber. Optical Fiber Patch Cord / Cable zoo ib yam li coaxial cables, tshwj tsis yog tias nws tsis muaj txheej thaiv mesh. Qhov chaw yog ib lub iav core rau lub teeb propagation. Hauv multimode optical fibers, txoj kab uas hla ntawm cov tub ntxhais yog 50 μ M ~ 65 μ m. Kwv yees li qhov tuab ntawm tib neeg cov plaub hau. Thiab txoj kab uas hla ntawm ib hom fiber ntau yog 8 μ M ~ 10 μ M. Cov txheej txheem txheej txheej ntawm cov tub ntxhais yog nyob ib puag ncig los ntawm lub hnab ntawv iav nrog qhov qis qis dua qhov ntsuas ntawm cov tub ntxhais, kom cov fiber ntau hauv cov tub ntxhais. Sab nraud yog ib lub tsho nyias nyias siv los tiv thaiv lub hnab ntawv.
