Ua raws li cov khoom sib txuas ntawm cov tub ntxhais, muaj ob hom xov tooj siv ntau. Lawv yog -
Kauj ruam-Performance index fiber- Qhov ntsuas qhov tsis yooj yim ntawm tus tub ntxhais yog qhov zoo thoob plaws thiab hla qhov hloov sai (lossis theem) ntawm tus ciam ciam.
Graded-index fiber ntau- Lub ntsiab lus tseem ceeb hloov los ua kom sib txawv raws li txoj haujlwm ntawm lub nrug deb ntawm qhov nruab nrab ntawm qhov fiber.
Ob qho no puav leej tau muab faib ntxiv -
Ib hom fiber ntau- Cov no muaj siab nrog laser.
Ntau hom fiber ntau- Cov no muaj siab nrog LED.
