Taw qhia
Raws li peb txhua tus paub, cov xim sib txawv ntawm lub tsho sab nrauv ntawm fiber ntau thaj qaum sawv cev rau ntau hom fiber ntau optic thaj qaum. Puas yog koj feem ntau tsis meej pem txog yuav ua li cas paub qhov txawv ntawm fiber ntau thaj qaum raws li xim ntawm lub tsho sab nrauv? Tsis txhob txhawj. Peb tuaj yeem xa mus rau EIA/TIA-598, tus qauv lees paub thoob ntiaj teb rau fiber ntau optic cable. Tsim los ntawm US Telecommunications Industry Association, EIA/TIA-598 txhais cov xim xim fiber ntau rau ntau hom fiber ntau thaj qaum. Cov cai qhia txog cov xim ntawm lub tsho sab nrauv, cov khoom sib txuas thiab fiber ntau optic, pab peb tswj cov fiber ntau thaj cords zoo dua thiab txo cov neeg ua yuam kev.
Xim ntawm Outer Jacket
Cov xim ntawm lub tsho sab nrauv ntawm cov hlua fiber ntau sib txawv nrog rau hom fiber ntau thiab daim ntawv thov ib puag ncig, raws li qhia hauv cov lus hauv qab no.
Ntxiv nrog rau cov xim tsho sab nrauv uas tau teev tseg hauv EIA/TIA-598 xim qauv, qee cov neeg muag khoom kuj tau faib cov hlua fiber ntau nrog cov qauv tshwj xeeb luam tawm ntawm lub tsho sab nrauv.
Xim ntawm Connector
Vim qhov sib txawv polishing rau fiber ntau connectors, fiber ntau xim coding feem ntau yog siv los sib txawv ntawm fiber ntau optic connector hom. Txawm li cas los xij, hlau fiber ntau optic connectors xws li FC thiab ST tsis tuaj yeem ua xim coded, yog li qee tus neeg muag khoom kos lawv siv lub tes tsho tshwj xeeb, cov xim uas yuav txawv ntawm tus neeg muag khoom rau tus neeg muag khoom.
Xim ntawm Fiber Optic
Raws li txhais los ntawm EIA/TIA-598, nyob rau hauv ib tug multi-core fiber optic thaj cable, cov fibers feem ntau yog xim coded nyob rau hauv pawg ntawm 12 thiab suav nyob rau hauv ib tug clockwise kev taw qhia.
Vim muaj qhov sib txawv ntawm fiber ntau cores, muaj ob qhov xwm txheej ntawm fiber ntau optic xim coding raws li hauv qab no.
Yog hais tias fiber cores muaj txog li 12: Yuav kom paub qhov txawv ntawm cov fibers sib txawv, txhua fiber ntau yuav raug cim nrog 12 xim sib txawv, xws li xiav rau thawj fibers thiab txiv kab ntxwv rau qhov thib ob, raws li cov lus qhia hauv qab no.
Yog tias cov cores fiber ntau ntau dua 12: Cov xim 12 yav dhau los feem ntau rov ua dua, tab sis cov fibers tau cim nrog lwm cov xim kom txawv lawv, piv txwv li 13th fiber ntau muaj lub tsho xiav sab nrauv nrog cov kab dub.
Xaus
Fiber optic xim coding pab peb kom pom cov hom fiber ntau optic thaj qaum thiab ua kom yooj yim rau kev tswj. Txawm li cas los xij, muaj ntau ntau hom thiab xim ntawm fiber ntau optic thaj qaum nyob rau hauv kev ua lag luam uas qee zaum nws tsis tuaj yeem paub qhov txawv ntawm lawv raws li cov ntaub ntawv no ib leeg, yog li koj tuaj yeem tshawb xyuas hom thiab qhov tshwj xeeb ntawm fiber optic thaj qaum los pab. koj zoo dua txawv lawv.
