Ntchito yayikulu ya cholumikizira cha fiber optic ndikulumikiza mwachangu ma ulusi awiriwo kuti chizindikiro cha kuwala chipitirize kupanga njira ya kuwala.Fiber optic connectors ndi mafoni, ogwiritsidwanso ntchito, ndipo ndizofunikira kwambiri komanso zomwe zimagwiritsidwa ntchito kwambiri pazigawo zoyankhulirana za optical.Zolumikizira za fiber optic zimalola kuti mbali ziwiri za mapeto a ulusi zikhale zogwirizana ndi matako kuti ziwonjezere kugwirizanitsa kwa mphamvu ya kuwala. kuchokera ku fiber yotumizira kupita ku fiber yomwe imalandira, ndipo zotsatira za dongosolo chifukwa cha kulowererapo ziyenera kuchepetsedwa.Chifukwa m'mimba mwake akunja kwa CHIKWANGWANI ndi 125um okha, ndipo kuwala kudutsa gawo laling'ono, single-mode CHIKWANGWANI ndi pafupifupi 9um, ndi multimode CHIKWANGWANI ndi 50um ndi 62.5um, kotero kugwirizana pakati ulusi ayenera kukhala ndendende. zogwirizana.
Zigawo zazikulu: ferrule
Kupyolera mu gawo la cholumikizira cha fiber optic, zitha kuwoneka kuti gawo lalikulu lomwe limakhudza magwiridwe antchito a cholumikizira ndi ferrule.Ubwino wa ferrule umakhudza mwachindunji docking yapakati pazitsulo ziwirizi.Nthawiyi imapangidwa ndi ceramic, zitsulo kapena pulasitiki.Ceramic ferrule imagwiritsidwa ntchito kwambiri, zinthu zazikulu ndi zirconium dioxide, zomwe zimakhala ndi kukhazikika kwabwino kwamafuta, kuuma kwakukulu, malo osungunuka kwambiri, kukana kuvala komanso kulondola kwambiri.Manja ndi gawo lina lofunikira la cholumikizira, ndipo manjawo amagwira ntchito ngati mayanidwe kuti athandizire kukwera kwa cholumikizira.M'kati mwake mwa malaya a ceramic ndi ocheperako pang'ono kuposa m'mimba mwake wakunja kwa ferrule, ndipo manja ong'ambika amamangitsa ma ferru awiriwa kuti agwirizane bwino.
Pofuna kupangitsa kuti mapeto a ulusiwo azilumikizana bwino, malekezero a ferrule nthawi zambiri amapangidwa mosiyanasiyana.PC, APC, ndi UPC zimayimira mawonekedwe akutsogolo a ceramic ferrule.PC ndi Physical Contact, kukhudzana ndi thupi. PC ndi yaying'ono-yozungulira pamwamba yopukutidwa ndi kupukutidwa, pamwamba pa ferrule imayikidwa pamalo ozungulira pang'ono, ndipo pakatikati pa chingwe cha kuwala chimakhala pamtunda wapamwamba kwambiri wopindika. Nkhope ziwiri za ulusi zimalumikizana ndi thupi.APC (Angled Physical Contact) imatchedwa kukhudzana kwa thupi, ndipo nkhope yamtundu wa ulusi nthawi zambiri imakhala pansi mpaka 8 ° bevel.8° angled bevel imapangitsa kuti kumapeto kwa ulusi kukhale kolimba komanso kumawonetsa kuwala kudzera pakona yake yopindika kupita ku chotchinga m'malo mobwerera komwe kumachokera, kumapereka kulumikizana kwabwinoko.UPC (Ultra Physical Contact), super physical end face.UPC idakhazikitsidwa pa PC kuti ikwaniritse kupukuta kumaso ndikumaliza, nkhope yomaliza imawoneka ngati dome.Zolumikizira zolumikizira ziyenera kukhala mu mawonekedwe a nkhope yofananira, mwachitsanzo APC ndi UPC sizingaphatikizidwe, zomwe zimapangitsa kuchepa kwa cholumikizira.
Zoyambira zoyambira: kutayika koyika, kutayika kobwerera
Chifukwa cha mawonekedwe osiyanasiyana amtundu wa ferrule, magwiridwe antchito a cholumikizira amakhalanso osiyana.Kuchita kwa kuwala kwa zolumikizira za fiber optic zimayesedwa makamaka ndi magawo awiri ofunikira: kutayika kwa kuyika ndi kutayika kobwerera.Ndiye, kutayika koyikako ndi chiyani?Kutayika kwa Insertion ("IL") ndiko kutayika kwa mphamvu ya kuwala chifukwa cha kugwirizana.Amagwiritsidwa ntchito kwambiri poyesa kutaya kwa kuwala pakati pa mfundo ziwiri zokhazikika mu ulusi, kawirikawiri chifukwa cha kupatuka kwapakati pakati pa ulusi awiriwo, kusiyana kwautali mu olowa CHIKWANGWANI, khalidwe la mapeto a nkhope, etc. Chigawo chimasonyezedwa mu decibels (dB).Zing'onozing'ono zimakhala bwino, zofunikira zonse siziyenera kupitirira 0.5dB.
Kubwerera Kutayika ("RL") kumatanthauza gawo la ntchito yowonetsera chizindikiro.Imalongosola kutayika kwa mphamvu kwa optical signal return/reflection.Nthawi zambiri, akakula bwino, mtengowo umawonetsedwa mu ma decibel (dB).Cholumikizira wamba cha APC chimakhala ndi mtengo wamba wa RL pafupifupi -60 dB ndipo cholumikizira cha PC chimakhala ndi mtengo wa RL pafupifupi -30 dB.
Kuphatikiza pa magawo awiri owoneka bwino a kutayika kwa kuyika ndi kutayika kobwerera, magwiridwe antchito a cholumikizira cha fiber optic ayeneranso kulabadira kusinthasintha, kubwereza, kulimba kwamphamvu komanso kutentha kwa ntchito kwa cholumikizira cha fiber optic., chiwerengero cha zolowetsa ndi zina zotero.
Mtundu wa cholumikizira
Zolumikizira zimagawidwa molingana ndi njira yolumikizira: LC, SC, FC, ST, MU, MT, MPO / MTP, etc.;malinga ndi nkhope yomaliza ya CHIKWANGWANI: FC, PC, UPC, APC.
LC cholumikizira
Cholumikizira chamtundu wa LC chimapangidwa ndi njira yosavuta yogwiritsira ntchito jack (RJ) latch.Kukula kwa zikhomo ndi manja omwe amagwiritsidwa ntchito mu LC chojambulira ndi 1.25 mm, yomwe ndi kukula kwa SC, FC, etc., kotero kukula kwakunja ndi theka la SC / FC.
SC cholumikizira
Chojambulira cha SC cholumikizira ('Subscriber Connector' kapena 'Standard Connector') ndi cholumikizira chokhazikika chokhazikika, chomwe chimangiriridwa ndi pulagi ndi kutsitsa, ndipo sichiyenera kuzunguliridwa.Cholumikizira chamtunduwu chimapangidwa ndi mapulasitiki aukadaulo, omwe ndi otsika mtengo komanso osavuta kuyika ndikuchotsa.
Cholumikizira cha FC
Chojambulira cha FC fiber (Ferrule Connector) ndi cholumikizira cha SC ndi kukula kofanana, kupatula kuti FC imapangidwa ndi manja achitsulo ndipo njira yomangirira ndiyotembenuza.Chitsanzo chothandizira chimakhala ndi ubwino wa kapangidwe kake, ntchito yabwino, kupanga kosavuta komanso kukhazikika, ndipo ingagwiritsidwe ntchito pamalo ogwedezeka kwambiri.
ST cholumikizira
Cholumikizira cha ST fiber optic (Nsonga Yowongoka) chili ndi chotchinga chakunja chozungulira chokhala ndi pulasitiki wokhala ngati mphete kapena chitsulo cha 2.5mm.Njira yokhazikika ndi turnbuckle, yomwe imagwiritsidwa ntchito kwambiri pamafelemu ogawa fiber.
Cholumikizira cha MTP/MPO
Cholumikizira cha MTP/MPO cha fiber optic ndi mtundu wapadera wa cholumikizira chamitundu yambiri.Mapangidwe a cholumikizira cha MPO ndizovuta, kulumikiza ulusi 12 kapena 24 mu ferrule yamakona anayi.Nthawi zambiri amagwiritsidwa ntchito pazinthu zolumikizirana kwambiri monga ma data center.
Kuphatikiza pazomwe zili pamwambapa, mitundu yolumikizira ndi MU zolumikizira, zolumikizira za MT, zolumikizira za MTRJ, zolumikizira E2000, ndi zina zotero.SC mwina ndi cholumikizira chogwiritsidwa ntchito kwambiri cha fiber optic, makamaka chifukwa cha kapangidwe kake kotsika mtengo.LC fiber optic connectors ndiwonso cholumikizira cha fiber optic chomwe chimagwiritsidwa ntchito kwambiri, makamaka polumikizana ndi SFP ndi SFP + fiber optic transceivers.FC imagwiritsidwa ntchito kwambiri mu single mode ndipo ndiyosowa mu multimode fiber.Zojambula zovuta komanso kugwiritsa ntchito zitsulo zimapangitsa kuti zikhale zodula.Zolumikizira za ST fiber optic nthawi zambiri zimagwiritsidwa ntchito pamapulogalamu aatali komanso aafupi monga masukulu ndi ma multimode fiber applications, mabizinesi apaintaneti, komanso ntchito zankhondo.
