Mapulojekiti apano ofooka akakumana ndi kufalikira kwa mtunda wautali, ma fiber optics amagwiritsidwa ntchito nthawi zambiri.Chifukwa mtunda wotumizira wa fiber fiber ndi wautali kwambiri, nthawi zambiri, mtunda wotumizira wa fiber single-mode ndi wopitilira makilomita 10, ndipo mtunda wotumizira wamitundu yambiri umatha kufikira makilomita awiri.
Mu fiber optic network, nthawi zambiri timagwiritsa ntchito ma transceivers a fiber optic.Ndiye, momwe mungalumikizire ma transceivers a fiber optic?Tiyeni tione limodzi.
Choyamba, ntchito ya fiber optic transceivers
① The Optical fiber transceiver imatha kukulitsa mtunda wotumizira wa Efaneti ndikukulitsa utali wozungulira wa Efaneti.
② The optical fiber transceiver imatha kusintha pakati pa 10M, 100M kapena 1000M Ethernet mawonekedwe amagetsi ndi mawonekedwe a kuwala.
③ Kugwiritsa ntchito ma transceivers a fiber optic kupanga netiweki kumatha kupulumutsa ndalama pamaneti.
④ Ma transceivers opanga ma fiber amapangitsa kulumikizana pakati pa ma seva, obwereza, ma hubs, ma terminals ndi ma terminals mwachangu.
⑤ Optical fiber transceiver ali ndi microprocessor ndi mawonekedwe owunikira, omwe angapereke zambiri zokhudzana ndi machitidwe a deta.
Chachiwiri, ndi transceiver iti yomwe transceiver yamaso ili nayo ndipo imalandira iti?
Mukamagwiritsa ntchito ma transceivers opangira ma fiber, anzanu ambiri amakumana ndi mafunso awa:
1.Kodi ma transceivers optical fiber ayenera kugwiritsidwa ntchito pawiri?
2.Kodi optical fiber transceiver yagawidwa kukhala imodzi yolandirira ndi imodzi yotumiza?Kapena kodi ma transceivers owoneka awiri okha angagwiritsidwe ntchito ngati awiri?
3. Ngati ma transceivers a fiber optical ayenera kugwiritsidwa ntchito pawiri, kodi ndikofunikira kuti akhale amtundu womwewo ndi chitsanzo?Kapena mtundu uliwonse ungagwiritsidwe ntchito kuphatikiza?
Yankho: Ma transceivers opangira ma fiber nthawi zambiri amagwiritsidwa ntchito pawiri ngati zida zosinthira zithunzi, koma ndizothekanso kuphatikiza ma fiber optic transceivers ndi ma switch switch, fiber optic transceivers ndi ma transceivers a SFP.M'malo mwake, malinga ngati kuwala kwa kuwala kwawavelength kumakhala kofanana Mtundu wa encapsulation wa chizindikiro ndi wofanana ndipo onse amathandizira protocol inayake kuti akwaniritse kulumikizana kwa fiber.
Kawirikawiri, single-mode dual-fiber (ziwiri zimayenera kulankhulana bwino) ma transceivers sagawidwa mu mapeto otumizira ndi mapeto olandira, ndipo angagwiritsidwe ntchito malinga ngati akuwonekera awiriawiri.
Ndi transceiver ya fiber imodzi yokha (chingwe chimodzi chimafunika kuti tizilankhulana bwino) chidzakhala ndi mapeto otumizira ndi olandira.
Mwa kuyankhula kwina, mitengo yosiyana (100M ndi Gigabit) ndi mafunde osiyanasiyana (1310nm ndi 1300nm) sangathe kulankhulana wina ndi mzake.Kuonjezera apo, ngakhale transceiver imodzi ya fiber ndi ulusi wapawiri wa mtundu womwewo umagwirizana, sizingatheke kulankhulana.Zogwirizana.
Ndiye funso ndilakuti, Kodi transceiver ya fiber imodzi ndi chiyani ndipo transceiver yamitundu iwiri ndi chiyani?Kodi pali kusiyana kotani pakati pawo?
Kodi single-fiber transceiver ndi chiyani?Kodi transceiver ya dual-fiber ndi chiyani?
Transceiver ya single-fiber imatanthawuza chingwe chokhala ndi mawonekedwe amodzi.Transceiver ya fiber imodzi imagwiritsa ntchito pachimake chimodzi ndipo mbali zonse ziwiri zimalumikizidwa pachimake ichi.Ma transceivers kumbali zonse ziwiri amagwiritsa ntchito mawonekedwe osiyanasiyana a kuwala, kotero amatha kufalikira mu chizindikiro chimodzi chapakati.
Transceiver yamitundu iwiri imagwiritsa ntchito ma cores awiri, imodzi yotumizira ndi ina yolandirira, ndipo mbali imodzi iyenera kuyikidwa kumapeto kwina, ndipo mbali ziwirizo ziyenera kuwoloka.
1.Single fiber transceiver
Transceiver ya single-fiber iyenera kukhazikitsa ntchito yotumizira komanso yolandila.Imagwiritsa ntchito ukadaulo wogawika wavelength kugawa kufalitsa ndikulandila ma siginecha awiri okhala ndi mafunde osiyanasiyana pamtundu umodzi wa kuwala.
Choncho, transceiver ya single-mode-fiber transceiver imafalitsidwa kudzera muzitsulo zamtundu wa optical, kotero kuwala kotumizira ndi kulandira kumafalikira kudzera mumtundu wa fiber panthawi yomweyo.Pamenepa, kuti tikwaniritse kulankhulana bwino, mafunde awiri a kuwala ayenera kugwiritsidwa ntchito kusiyanitsa.
Chifukwa chake, gawo la optical la single-mode single-fiber transceiver lili ndi mafunde awiri a kuwala kotulutsa, nthawi zambiri 1310nm / 1550nm.Mwanjira iyi, pali kusiyana pakati pa mbali ziwiri za transceivers:
Transceiver kumbali imodzi imatumiza 1310nm ndikulandira 1550nm.
Mapeto ena amatulutsa 1550nm ndikulandira 1310nm.
Chifukwa chake ndikosavuta kwa ogwiritsa ntchito kusiyanitsa, ndipo nthawi zambiri amagwiritsa ntchito zilembo m'malo mwake.
A-terminal (1310nm / 1550nm) ndi B-terminal (1550nm / 1310nm) adawonekera.
Ogwiritsa ntchito ayenera kugwiritsa ntchito AB pairing, osati AA kapena BB kulumikizana.
Mapeto a AB amangogwiritsidwa ntchito pa ma transceivers a fiber optic amodzi.
2.Dual fiber transceiver
Transceiver yapawiri-fiber ili ndi doko la TX (chotumiza) ndi doko la RX (doko lolandila).Madoko onsewa amafalikira pamtunda womwewo wa 1310nm, ndipo kulandirirako kulinso 1310nm.Choncho, zingwe ziwiri zofanana za kuwala zomwe zimagwiritsidwa ntchito popanga mawaya ndizolumikizana.
3. Kodi mungasiyanitse bwanji transceiver ya fiber imodzi ndi transceiver ya ulusi wapawiri?
Panopa pali njira ziwiri zosiyanitsira ma transceivers a fiber single kuchokera ku ma transceivers a fiber-fiber.
①Pamene transceiver ya kuwala imayikidwa ndi module ya optical, transceiver optical imagawidwa kukhala transceiver ya fiber imodzi ndi transceiver yawiri-fiber malinga ndi chiwerengero cha ma cores a optical fiber jumper yolumikizidwa.Mzere wa optical fiber jumper wolumikizidwa ndi transceiver ya fiber imodzi (kumanja) ndi fiber core, yomwe imayang'anira kutumiza ndi kulandira deta;Mzerewu uli ndi mitundu iwiri.Chigawo chimodzi chimakhala ndi udindo wotumiza deta ndipo pachimake china chimakhala ndi udindo wolandira deta.
②Pamene transceiver ya fiber optical ilibe optical module yophatikizidwa, m'pofunika kusiyanitsa pakati pa transceiver ya fiber imodzi ndi transceiver yamtundu wapawiri malinga ndi gawo la optical module.Pamene imodzi ya fiber bidirectional optical module imalowetsedwa mu optical fiber transceiver, ndiko kuti, mawonekedwe ndi mtundu wa simplex, optical fiber transceiver ndi transceiver ya fiber imodzi (chithunzi choyenera);pamene ma module awiri a fiber bidirectional optical module amalowetsedwa mu transceiver ya optical fiber, Ndiko kuti, pamene mawonekedwewo ndi amtundu wa duplex, transceiver iyi ndi yapawiri-fiber transceiver (chithunzi chakumanzere).
Chachinayi, chizindikiro ndi kugwirizana kwa optical fiber transceiver
1. Chizindikiro cha optical fiber transceiver
Pachizindikiro cha optical fiber transceiver, tili ndi nkhani yapitayi yokhudzana ndi izi.
Apa tikubwerezanso chithunzi kuti timveke bwino.
2.Fiber optic transceiver kugwirizana
