Peb txhua tus paub tias optical fiber jumper yog cov khoom siv dav siv hauv kev sib txuas lus hauv kev sib txuas lus kho qhov muag. Nws tuaj yeem txuas ntau yam khoom siv hauv network thiab cov khoom siv nrog optical fiber ntau interfaces, xws li Optical module, adapter vaj huam sib luag, tis lub thawv, Wavelength-division multiplexing thiab demultiplexer, optical transceiver, thiab lwm yam. Hauv qab no yog phau ntawv qhia kev saib xyuas rau fiber ntau optic jumpers.
1. Ntxuav cov fiber ntau optic jumpers kom raws sijhawm
Kev sib kis ntawm cov connectors ntawm fiber ntau optic jumpers yog ib qho tseem ceeb ua rau lub network tsis ua haujlwm, thiab kev sib kis ntawm fiber ntau lub ntsej muag ntawm cov connectors nrog plua plav tuaj yeem ua rau cov teeb liab tsis zoo ntawm cov khoom siv kho qhov muag. Qhov chaw tseem ceeb rau kev tu cov fibers optical yog nyob rau ntawm qhov txuas txuas ntawm ob qhov kawg, thiab muaj ob txoj kev tu lub ntsiab: kev tu kom qhuav thiab ntub dej. Feem ntau siv cov ntxhua khaub ncaws qhuav xws li cassette hom fiber optic tu lub thawv thiab ib tus nias tu cwj mem, thaum cov ntxhua khaub ncaws ntub dej tsis muaj plua plav so daim ntawv, ntxuav cov nplaum, thiab lwm yam.
2. Khaws cov fiber ntau optic jumpers kom raug
Txawm hais tias lub fiber optic jumper siv los yog tsis, tsis txhob khoov ntau dhau los yog ncab nws. Qee qhov kev puas tsuaj los ntawm kev khoov yog pom ntawm qhov muag liab qab, txawm li cas los xij, qee zaum, qhov poob yuav tsis yooj yim txiav txim siab, xws li micro deformation ntawm optical fibers tshwm sim los ntawm qhov kub thiab txias, millimeter theem hloov chaw los ntawm qhov tsis xws luag hauv buffers lossis tsho. , kev teeb tsa tsis zoo, lossis lwm yam. Vim tias qhov kev puas tsuaj zoo li no tsis tuaj yeem tshawb pom ncaj qha, nws feem ntau tsis saib xyuas, thiab nyob rau lub sijhawm ntev, nws yuav ua rau muaj teeb meem ntau dua. Txhawm rau kom tsis txhob poob ntxiv, peb yuav tsum ua tib zoo mloog cov ntsiab lus hauv qab no:
(1) Tsis txhob khoov fiber ntau optic jumpers tshaj lawv qhov tsawg kawg nkaus khoov vojvoog, tshwj xeeb tshaj yog nyob rau hauv qhov chaw nqaim ntawm high-density fiber optic thaiv.
(2) Hloov kho fiber ntau optic jumper txoj hauv kev nrog cov cuab yeej tsim nyog los tiv thaiv cov kab hluav taws xob los ntawm kev puas tsuaj, xws li kab rov tav cable racks.
(3) Tsis txhob sib tsoo nrog lub fiber optic connector, vim nws yuav hnav lub ntsej muag kawg thiab cov khib nyiab tuaj yeem ua rau tawv nqaij. Yog li ntawd, nws raug pom zoo kom muab lub kaus mom plua plav ntawm lub jumper txhua lub sijhawm.
(4) Optical time-domain reflectometer (OTDR) thiab optical fiber microscope tuaj yeem siv tau yog tias cov cuab yeej yuav tsum tau kuaj xyuas thiab txheeb xyuas qhov tsis raug, xws li kev puas tsuaj thiab tag nrho cov attenuation hauv optical fiber jumper.
