Lub ntsiab yam ua rau attenuationntawm fiberLawv yog: intrinsic, dabtsi yog khoov, extrusion, impurities, non-uniformity thiab coupling.
1. Intrinsic: Nws yog lub hauv paus poob ntawm fiber ntau, xws li: Rayleigh scattering, intrinsic absorption, thiab lwm yam.
2. Khoov: Thaum kho qhov muag fiber ntau yog khoov, qee qhov ntawm lub teeb nyob rau hauv qhov kho qhov muag fiber ntau yuav ploj vim dispersion, ua rau poob.
3. Squeeze: Qhov poob tshwm sim los ntawm kev khoov me ntsis ntawm cov khoom siv kho qhov muag thaum nws nyem.
4. Impurity: Qhov poob los ntawm impurities nyob rau hauv fiber ntau uas nqus thiab tawg lub teeb propagating nyob rau hauv fiber.
5. Tsis sib xws: Qhov poob los ntawm qhov tsis sib xws refractive index ntawm cov khoomfiber ntau.
6. Butt Joint: Qhov poob generated thaum lub optical fiber yog txuas, xws li: tsis-axial (lub coaxiality ntawm ib hom optical fiber yuav tsum tsawg tshaj li 0.8 μm), lub ntsej muag kawg tsis yog perpendicular rau lub axis, Lub ntsej muag kawg tsis tiaj tus, lub taub qab lub taub hau tsis sib xws, thiab qhov vuam zoo tsis zoo.
