Kuti zitsimikizire kuti zizindikiro zotumizira mauthenga akutali komanso otsika mtengo zimagwiritsidwa ntchito, chingwe cha fiber optic chiyenera kukwaniritsa zochitika zina zachilengedwe. Kupindika pang'ono kapena kuipitsidwa kwa zingwe zowonera kungayambitse kuchepa kwa zizindikiro zowonera komanso kusokoneza kulumikizana.
1. Utali wa mzere wolumikizira chingwe cha fiber optic
Chifukwa cha mawonekedwe a zingwe zowunikira komanso kusalingana kwa njira zopangira, zizindikiro zowunikira zomwe zimafalikira mkati mwake zimafalikira nthawi zonse ndikuyamwa. Pamene chingwe cha fiber optic chili chachitali kwambiri, zimapangitsa kuti chizindikiro chonse cha kuwala cha chingwe chonsecho chichepetsedwe kuposa zofunikira pakukonza netiweki. Ngati kuchepa kwa chizindikiro cha kuwala kuli kwakukulu kwambiri, kumachepetsa mphamvu yolumikizirana.
2. Ngodya yopindika ya malo oyika chingwe cha kuwala ndi yayikulu kwambiri
Kuchepa kwa kupindika ndi kupsinjika kwa zingwe za kuwala kumachitika makamaka chifukwa cha kusintha kwa zingwe za kuwala, zomwe zimapangitsa kuti zisamakwanitse kuwunikira konse panthawi yotumiza kuwala. Zingwe za fiber optic zimakhala ndi kupindika kwinakwake, koma chingwe cha fiber optic chikapindika pa ngodya inayake, chimayambitsa kusintha kwa njira yofalitsira chizindikiro cha kuwala mu chingwe, zomwe zimapangitsa kuti kupindika kukhale kochepa. Izi zimafuna chisamaliro chapadera kuti zisiye ma angles okwanira kuti zilumikizane panthawi yomanga.
3. Chingwe cha fiber optic chimapanikizika kapena kusweka
Imeneyi ndi vuto lofala kwambiri pa kulephera kwa chingwe cha kuwala. Chifukwa cha mphamvu zakunja kapena masoka achilengedwe, ulusi wa kuwala ukhoza kukhala ndi mapindidwe ang'onoang'ono osakhazikika kapena kusweka. Kuswekako kukachitika mkati mwa bokosi la splice kapena chingwe cha kuwala, sikungadziwike kuchokera kunja. Komabe, pamalo osweka ulusi, padzakhala kusintha kwa refractive index, komanso kutayika kwa reflection, zomwe zidzawononga khalidwe la chizindikiro chotumizidwa cha ulusi. Pakadali pano, gwiritsani ntchito choyezera chingwe cha kuwala cha OTDR kuti mupeze reflection peak ndikupeza internal bending attenuation kapena fracture point ya ulusi wa kuwala.
4. Kulephera kwa kuphatikizika kwa ma fiber optic joint construction
Poika zingwe zowunikira, nthawi zambiri ma fiber fusion splicers amagwiritsidwa ntchito kuphatikiza magawo awiri a ulusi wa kuwala kukhala chimodzi. Chifukwa cha fusion splicing ya ulusi wagalasi mkati mwa chingwe cha kuwala, ndikofunikira kugwiritsa ntchito fusion splicer molondola malinga ndi mtundu wa chingwe chowunikira panthawi yomanga fusion splicing. Chifukwa chakuti ntchitoyo sikugwirizana ndi zofunikira pakupanga ndi kusintha kwa malo omanga, n'zosavuta kuti ulusi wa kuwala udetsedwe ndi dothi, zomwe zimapangitsa kuti zinyalala zisakanizike panthawi yophatikiza fusion splicing ndikupangitsa kuti kulumikizana konse kuchepe.
5. Ulalo wa waya wapakati wa fiber umasiyana
Chingwe cha kuwala kwa fiberKuyika nthawi zambiri kumagwiritsa ntchito njira zosiyanasiyana zolumikizirana, monga kulumikizana kwa flange, komwe kumagwiritsidwa ntchito kwambiri pakuyika maukonde a makompyuta m'nyumba. Kulumikizana kogwira ntchito nthawi zambiri kumakhala ndi kutayika kochepa, koma ngati mbali yomaliza ya ulusi wowala kapena flange siili yoyera panthawi yolumikizirana, kukula kwa ulusi wowala wa core kumakhala kosiyana, ndipo cholumikizira sichili cholimba, chidzawonjezera kwambiri kutayika kwa cholumikizira. Kudzera mu OTDR kapena kuyesa kwa mphamvu ziwiri, zolakwika za core diameter mismatch zitha kupezeka. Tiyenera kudziwa kuti ulusi wa single-mode ndi ulusi wa multi-mode zili ndi njira zosiyana zotumizira, ma wavelength, ndi njira zochepetsera kupatula kukula kwa ulusi wowala, kotero sizingasakanizidwe.
6. Kuipitsidwa kwa cholumikizira cha fiber optic
Kuipitsidwa kwa maulumikizidwe a fiber ya mchira ndi chinyezi chodumpha ulusi ndiye zifukwa zazikulu zomwe zimapangitsa kuti chingwe cha optical chilephereke. Makamaka m'maukonde amkati, pali ulusi wambiri waufupi ndi zida zosiyanasiyana zosinthira maukonde, ndipo kuyika ndi kuchotsa zolumikizira za fiber optic, kusintha flange, ndi kusinthana kumachitika kawirikawiri. Panthawi yogwira ntchito, fumbi lochuluka, kutayika kwa kulowetsa ndi kutulutsa, komanso kukhudza chala kumatha kupangitsa kuti cholumikizira cha fiber optic chikhale chodetsedwa mosavuta, zomwe zimapangitsa kuti chisathe kusintha njira ya optical kapena kuchepetsa kuwala kwambiri. Ma swab a mowa ayenera kugwiritsidwa ntchito poyeretsa.
7. Kupukuta koyipa pa malo olumikizirana mafupa
Kupukuta bwino kwa maulumikizidwe ndi chimodzi mwa zolakwika zazikulu mu maulumikizidwe a fiber optic. Gawo labwino kwambiri la fiber optic silipezeka m'malo enieni enieni, ndipo pali ma undulations kapena malo otsetsereka. Pamene kuwala mu chingwe cha optical cable link kukumana ndi gawo lotere, malo osakhazikika a joint amayambitsa kufalikira kwa kuwala ndi kuwonetsa kuwala, zomwe zimawonjezera kwambiri kuchepa kwa kuwala. Pa curve ya OTDR tester, dera lochepetsera kuwala la gawo lopukutidwa bwino ndi lalikulu kwambiri kuposa la nkhope yanthawi zonse.
Mafunso Ofunsidwa Kawirikawiri
Kodi doko lowala la switch liyenera kuyatsidwa?
Ma switch osakonzedwa a network management, kupatulapo optical port ya optical multiplexing port yomwe ikufunika kuyatsidwa, ma switch ena onse ali ndi ma plug and play optical ports omwe safuna kuti ma configuration ayatsidwe.
Ndiyenera kuchita chiyani ngati chowunikiracho sichikuyaka?
1. Chongani ngati doko la kuwala la chipangizocho ndi liwiro la gawo la kuwala lomwe lagwiritsidwa ntchito zikugwirizana.
2. Onetsetsani ngati ma module opangidwa ndi kuwala omwe amagwiritsidwa ntchito kumapeto onse awiri aphatikizidwa.
3. Onetsetsani ngati ulusi womwe wagwiritsidwa ntchito ukugwirizana ndi module ya optical. Module ya optical ya single mode imagwiritsa ntchito ulusi wa single-mode, module ya optical ya multi-mode imagwiritsa ntchito ulusi wa multi-mode, module ya optical ya dual fiber, ndipo ulusi awiri omwe ali kumapeto amodzi amasinthidwa kumanzere ndi kumanja.
4. Onetsetsani ngati ulalo wa fiber optic uli bwino ndipo gwiritsani ntchito ulusi waufupi poyesa.
5. Pakati pa ceramic ya optical module, tail fiber, kapena optical module ndi yodetsedwa kwambiri.
6. Cholumikizira cha optical kapena ulusi wamchira chawonongeka, kapena kusakanikirana kwa ulusi sikwabwino.
Zolakwika zokhudzana ndi fiber optic ndi zolakwika zomwe zimaonekera kwambiri komanso zomwe zimachitika kawirikawiri mukakonza zolakwika kapena kukonza. Chifukwa chake, chida chikufunika kuti muwone ngati kuwala kwa fiber optic kuli bwino. Izi zimafuna kugwiritsa ntchito zida zodziwira zolakwika za fiber optic, monga zoyezera mphamvu zamagetsi ndi zolembera zofiira. Zoyezera mphamvu zamagetsi zimagwiritsidwa ntchito poyesa kutayika kwa fiber optic ndipo ndizosavuta kugwiritsa ntchito, zosavuta, komanso zosavuta kugwiritsa ntchito, zomwe zimapangitsa kuti zikhale chisankho chabwino kwambiri pothetsa mavuto a fiber optic. Cholembera chofiira chimagwiritsidwa ntchito kupeza diski ya fiber optic yomwe fiber optic ili. Zida ziwiri zofunika kwambiri pothetsa mavuto a fiber optic, koma tsopano choyezera mphamvu zamagetsi ndi cholembera chofiira zimaphatikizidwa kukhala chida chimodzi, chomwe chili chosavuta kugwiritsa ntchito.
