Cov khoom tseem ceeb ntawm cov fiber ntau yog iav fiber. Cov khoom tseem ceeb ntawm cov iav fiber yog silica uas muaj purity siab. Nws raug ci rau hauv cov fiber ntau preform ntawm qhov kub ntawm 1500 degrees Celsius. Tom qab tsim cov fiber ntau preform, nws raug muab tso rau hauv lub thav duab kos duab. Lub raj annealing ntev 7,500-kilometer raug ntxuav kom tiv thaiv cov khoom tsis huv thiab hmoov av los ntawm kev poob rau ntawm cov fiber ntau thiab yaj rau hauv lub embryo mos ntawm qhov kub siab ntawm 2,200 degrees Celsius. Tom qab dhau los ntawm lub cub tawg, nws tuaj yeem rub tawm tas li. Lub raj annealing ntev 1-meter maj mam txias kom tsim cov fiber nrog lub cheeb ntawm 0.1 hli. Lub tshuab winding tig los tsav cov fiber kos duab thiab ua tiav cov fiber ntau sib dhos. Cov fiber ntau, ua los ntawm iav fiber, tuaj yeem xa cov teeb liab optical hla ntau txhiab mais. Pua pua lossis ntau txhiab tus fiber ntau tau sib xyaw ua ke los tsim cov xov hlau optical, uas tsis tsuas yog txhim kho lub zog ntawm cov fiber tab sis kuj ua rau muaj peev xwm sib txuas lus ntau ntxiv.
Qhov no yog cov txheej txheem tsim khoom ntawm cov fiber ntau optical. Qhov tsim tawm yog cov iav fiber ntau nyias nyias. Yog tias koj yaj cov fiber, koj yuav pom tias txhua lub xov hlau optical yog cov iav fiber pob tshab thaum nws raug tev tawm. Nws yooj yim tawg thiab yooj yim tawg, tab sis txawm tias koj rub npaum li cas los xij, koj tsis tuaj yeem rub ntxiv lawm. Yog vim li cas, thaum splicing fibers, koj feem ntau hnov cov neeg laus hais tias cov fiber ntau optical tsis tuaj yeem khoov thiab tawg yooj yim. Qhov no yog tus yam ntxwv ntawm cov fiber ntau optical.
Cable kho qhov muag
Hauv cov lus yooj yim, ib txoj hlua fiber ntau muaj ntau txoj hlua fiber ntau uas hla dhau ib lub plhaub tom qab ua tiav thiab txheej tiv thaiv los ntawm txheej. Qhov no tso cai rau cov fiber ntau fiber ntau xa cov ntaub ntawv hauv ob qho chaw sab hauv tsev thiab sab nraum zoov yam tsis tas yuav txiav tawm yooj yim, ua rau nws hloov tau raws li ntau qhov chaw. Raws li qhov tseem ceeb rau kev xa cov ntaub ntawv ceev ceev, cov hlua fiber ntau fiber ntau cuam tshuam rau peb lub neej. Hom nrov tshaj plaws yog fiber-to-the-home (FTTH). Txawm hais tias technically hu ua fiber-to-the-home, nws yog ib txoj hlua fiber ntau nyias hu ua sheathed optical cable. Cov hom hlua fiber ntau yog: 6-core, 8-core, 12-core, 48-core, 72-core, 96-core, 144-core, 288-core, thiab lwm yam. 6, 8, 12, 24, thiab 48-core optical cables yog cov siv ntau tshaj plaws.
Qhov txawv ntawm cov fiber ntau optical thiab cov cable optical: Feem ntau hais lus, cov fiber ntau optical yog cov cable optical, uas yog cov khoom xa mus. Tab sis hais lus nruj me ntsis, ob qho no yog cov khoom sib txawv. Qhov txawv ntawm cov fiber ntau optical thiab cov cable optical: Cov fiber ntau optical yog cov khoom nyias nyias, yooj ywm uas xa cov teeb ci. Feem ntau cov fiber ntau optical yuav tsum tau coated nrog ntau txheej ntawm cov qauv tiv thaiv ua ntej siv. Cov cable coated hu ua cov cable optical. Yog li ntawd, cov fiber ntau optical yog lub hauv paus ntawm cov cable optical thiab tau tiv thaiv los ntawm qee cov khoom pabcuam thiab cov txheej tiv thaiv los tsim cov cable optical.
