    Chidule cha zovuta zomwe zimachitika mu fiber optic transceivers

    Post Nthawi: Oct-12-2019

    Mavuto omwe adakumana nawo mu kukhazikitsa ndikugwiritsa ntchito ma tracker optic

    Gawo 1: Choyamba, kodi mukuwona ngati chisonyezo cha transceiver kapena gawo lowoneka bwino komanso chizindikiritso cha padoko?

    1.Ngati koloko (FX) ya wotchinga ili ndi port (FX) kuzindikiritsa kwa B Kutumiza kochokera ku doko kumasweka chifukwa doko lowoneka bwino la b jumper yasweka.

    2.Ngati doko lowoneka bwino (FX) la transceiver silikuwunikire, onani ngati ulalo wa fiber umalumikizidwa. Jiber jumper imalumikizidwa mofananamo ndipo inayo ndi yolumikizirana.

    3. Awiri opindika (TP) siyikuwala. Chonde onetsetsani kuti zingwe zopotoka ndizolakwika kapena zolumikizidwa molakwika. Chonde gwiritsani ntchito zotsatsa kuti mufufuze.

    4.masiwichindi mzere wowongoka. (Tonode) akuwonetsa kuti mzere wolumikizira kulumikizanamasiwichindi mzere.

    5.Some zotumiza zili ndi MPRkusinthaMbali: Chingwe cholumikizirana cholumikizamasiwichindi mzere wowongokakusintha: mzere wolumikizana wolumikizamasiwichindi njira yodutsa.

    Gawo 2: Fungani ngati pali vuto ndi mphete ya fiber ndi chingwe?

    Kulumikizana kwa fiber 1.Ptical: Gwiritsani ntchito nyali ya laser, kuwala kwa dzuwa, etc. Kuwunikira jumper.see ngati pali kuwala kumapeto kwina? Ngati pali kuwala kowoneka, jumper jumper siyikusweka.

    2.Kunika kotsalira: Ngati pali kuwala kowoneka, chingwecho sichinasweka.

    Gawo 3: Kodi Fodya / Yathunthu Puplex Vuto Lolakwika?

    Ma transceivers ena ali ndi FDXmasiwichikumbali: duplex yodzaza; Zithunzi za HDXmasiwichi: half duplex.

    Gawo 4: Pogwiritsa ntchito magetsi amphamvu a meta

    Mphamvu yowala ya transceal transceiver kapena module yowoneka bwino kwambiri: -10db-18db; mode imodzi 20km: -8db-15db; Mode Osakwatira 60kM: -5db-12DB ngati mphamvu yowunikira ma transceil ndi pakati -30db-45dB, ndiye kuti zitha kuweruzidwa kuti pamapeto pake pa transceiver iyi.

    Othamangitsa owoneka ayenera kumvetsera nkhani

    Chifukwa cha kuphweka, ndibwino kukhala ndi funso ndikuyankha kayendedwe, komwe kumatha kuchitika.

    1.Kodi tradial transceiver yomwe imathandizira Duplex ndi theka-duplex?

    Tchipisi china pamsika chikhoza kungogwiritsa ntchito malo anthawi zonse pakalipano, ndipo sindingathe kuthandizira theka la Duplex. Ngati mumalumikizana ndi mitundu ina yamasiwichi (SINTHA) kapena Hub (HUB), ndipo imagwiritsa ntchito modex pang'ono, zimayambitsa mikangano yayikulu ndi kuyika kwapadera.

    2.Anayesedwa kuti mulumikizane ndi zikwangwani zina za fiber?

    Pakadali pano pali zosintha zambiri zamisika yambiri pamsika. Mwachitsanzo, ngati kugwirizana kwa mitundu yosiyanasiyana ya ma transceints sikunayesedwepo, kumabweretsanso kuwonongeka kwa mapaketi, nthawi yayitali youndadwa, komanso mwachangu komanso pang'onopang'ono.

    3.Kodi pali chipangizo chotetezedwa kuti chitetezeke pacle?

    Opanga ena amagwiritsa ntchito njira yolembetsa deta kuti achepetse ndalama popanga ma trans optic. kutaya paketi.

    4.Temited kusinthidwa?

    Pamene chizungu cha fiber Optic chomwe chimagwiritsidwa ntchito, chimapanga kutentha kwambiri. Kutentha kumakhala kwakukulu kwambiri (osati kupitirira 50 ° C), kaya ndi hubere transceiver ntchito nthawi zambiri ndi chifukwa choyenera kuganizira ndi makasitomala!

    5.Kodi pali Ieee802.3U muyezo?

    Ngati ma track amayendetsa masitepe amakumana ndi Ieee802.3 Muyeso, ndiye kuti, nthawi yachedwa imayendetsedwa m'mabati 46. Ngati ipitilira ma bits 46, mtunda woperekedwa ndi womasulira wa Optial afupikitsidwa.

    6. Ntchito yogulitsa:

    Pofuna kupanga ntchito yogulitsa pambuyo poti alande mofulumira komanso molawirira kuti makasitomala agule makonda a fiber-Optic Malinga ndi mphamvu ya wopanga, ukadaulo, mbiri ina ndi makampani ena.
