Zolumikizira zamagetsi zimagwiritsidwa ntchito polumikizana pakati pa zida zapaintaneti pazida zama data komanso kulumikizana kwaCHIKWANGWANI chamawonedwe chingweku zipangizo pa malo kasitomala (monga FTTH).Pakati pa mitundu yosiyanasiyana ya cholumikizira CHIKWANGWANI, SC ndi LC ndi ziwiri zolumikizira zomwe zimagwiritsidwa ntchito kwambiri.SC vs LC: pali kusiyana kotani ndipo ndi iti yomwe ili bwino?Ngati mulibe yankho panobe.Mutha kupeza chidziwitso apa.
Kodi SC Connector ndi chiyani?
Wopangidwa ndi ma laboratories ku Nippon Telegraph ndi Telephone (NTT) chapakati pa zaka makumi asanu ndi atatu, cholumikizira cha SC chinali chimodzi mwazolumikizira zoyamba kugundika pamsika kutsatira kubwera kwa ma ferrules a ceramic.Nthawi zina amatchedwa "square cholumikizira" SC imakhala ndi nkhope yolumikizirana ndi kasupe yokhala ndi ferrule ya ceramic.Poyamba ankafuna kuti Gigabit Ethernet networking, igwirizane ndi telecommunication specifications TIA-568-A mu 1991 ndipo inakula pang'onopang'ono kutchuka pamene ndalama zopangira zidatsika.Chifukwa chakuchita bwino kwambiri idalamulira ma fiber optics kwazaka zopitilira khumi ndi ST yokha yomwe idapikisana nayo.Zaka makumi atatu kupitilira, ikadali cholumikizira chachiwiri chodziwika bwino pakusunga ma polarization.SC ndiyoyenera kugwiritsa ntchito ma datacoms ndi ma telecom, kuphatikiza point to point ndi passive optical network.
Kodi LC Connector ndi chiyani?
Ena amaona ngati cholumikizira chamakono cha SC, kukhazikitsidwa kwa cholumikizira cha LC sikunachite bwino, mwina chifukwa cha chindapusa chokwera kuchokera kwa wopanga Lucent Corporation.Monga cholumikizira chokokeranso, LC imagwiritsa ntchito latch mosiyana ndi tabu yotsekera ya SC ndipo yokhala ndi ferrule yaying'ono imadziwika ngati cholumikizira chaching'ono.Kukhala ndi theka la phazi la cholumikizira cha SC kumapangitsa kutchuka kwakukulu mu ma datacoms ndi ntchito zina zochulukira kwambiri, chifukwa kuphatikiza kwake kakang'ono kakang'ono ndi mawonekedwe a latch kumapangitsa kukhala koyenera kwa ma rack / mapanelo okhala ndi anthu ambiri.Ndi kukhazikitsidwa kwa ma transceivers ogwirizana a LC ndi zida zogwirira ntchito zapaintaneti, kukula kwake kokhazikika mubwalo la FTTH kuyenera kupitilirabe.
SC vs LC: Momwe Amasiyanirana ndi Wina ndi Mnzake
Mutatha kumvetsetsa zolumikizira zonse za SC ndi LC, mutha kufunsa kuti pali kusiyana kotani ndipo akutanthauza chiyani pakukhazikitsa kwanu?Gome ili m'munsili likupereka chithunzithunzi cha mphamvu ndi zofooka.Ndipo kawirikawiri, kusiyana pakati pa LC ndi SC fiber optic cholumikizira chagona pakukula, kagwiridwe ndi mbiri yolumikizira, zomwe zidzakambidwe motsatana m'mawu otsatirawa.
- Kukula: LC ndi theka la kukula kwa SC.Kwenikweni, imodzi SC-adaputala ndi chimodzimodzi kukula ngati duplex LC adaputala.Chifukwa chake LC ndiyofala kwambiri m'maofesi apakati pomwe kachulukidwe (chiwerengero cha maulumikizidwe pagawo lililonse) ndichofunika kwambiri.
- Kugwira: SC ndi "push-pull-connector" yowona ndipo LC ndi "cholumikizira cholumikizira", ngakhale pali zatsopano, zenizeni "Push-pull-LCs" zomwe zilipo zomwe zili ndi mphamvu zofanana zogwirira ntchito monga SC.
- Mbiri ya Cholumikizira: LC ndi "wamng'ono" cholumikizira cha awiriwo, SC ikufalikira padziko lonse lapansi koma LC ikugwira.Zolumikizira zonse ziwiri zimakhala ndi kutayika kofanana koyika ndi kubweza kutayika.Nthawi zambiri, zimatengera komwe mukufuna kugwiritsa ntchito netiweki, ziribe kanthu SC kapena LC, ngakhale mitundu ina yolumikizirana.
Chidule
Ukadaulo wamakono komanso wamtsogolo wolumikizirana umafuna kugwira ntchito mwachangu, koyenera komanso kotetezeka pakulumikizana kwa data.Zosungira zazikulu ndi zovuta zonse zolumikizidwa ziyenera kulandira ndi kutumiza deta popanda kusokoneza kunja.Onse SC ndi LC adapangidwa kuti akwaniritse kufala kotereku.Ponena za funso lakuti "SC vs LC: ndi kusiyana kotani ndi komwe kuli bwino?", Mukungoyenera kukumbukira mfundo zitatu zofunika: 1. SC ili ndi nyumba yolumikizira yokulirapo komanso 2.5mm ferrule yayikulu.2. LC ili ndi nyumba yaing'ono yolumikizira ndi ferrule yaying'ono ya 1.25mm.3. SC kale anali ukali wonse, koma tsopano ndi LC.Mutha kukwanira zolumikizira zambiri pamakadi amzere, mapanelo, ndi zina zambiri ndi cholumikizira cha LC.
