Optical fiber transceiver ndi Ethernet transmission media conversion unit yomwe imasintha ma siginecha amagetsi opindika mtunda waufupi ndi ma sign atali atali.Imatchedwanso fiber converter m'malo ambiri.
Ma transceivers opangira ma fiber nthawi zambiri amagwiritsidwa ntchito m'malo enieni amtaneti omwe sangathe kutsekedwa ndi zingwe za Efaneti ndipo amayenera kugwiritsa ntchito ulusi wowoneka bwino kuti atalikitse mtunda wotumizira, ndipo nthawi zambiri amakhala m'malo ogwiritsira ntchito ma network a Broadband Metropolitan Area;monga: kufalitsa chithunzithunzi chapamwamba cha kanema wowunikira ndi uinjiniya wachitetezo;Zimagwiranso ntchito yayikulu pothandizira kulumikiza mtunda womaliza wa fiber kupita ku metro ndi kupitilira apo.
Optical fiber transceivers amakumana ndi zovuta zosiyanasiyana pakagwiritsidwa ntchito.Lero, ndikugawana nanu zolakwika zodziwika bwino komanso zothetsera ma transceivers optical fiber.
1. Kuwala kwa Link kwazimitsidwa
(1) Onani ngati chingwe cha optical fiber chathyoka;
(2) Onani ngati kutayika kwa chingwe cha optical fiber ndi chachikulu kwambiri ndipo kumaposa kulandirira kwa zida;
(3) Onani ngati mawonekedwe a fiber optical alumikizidwa molondola, TX yakomweko imalumikizidwa ndi RX yakutali, ndipo TX yakutali imalumikizidwa ndi RX yakumaloko.
(4) Onani ngati cholumikizira cholumikizira chimayikidwa bwino mu mawonekedwe a chipangizocho, ngati mtundu wa jumper umagwirizana ndi mawonekedwe a chipangizocho, ngati mtundu wa chipangizocho umagwirizana ndi ulusi wa kuwala, komanso ngati kutalika kwa chipangizocho kumagwirizana ndi mtunda.
2. Kuwala kwa chigawo cha Link kwazimitsidwa
(1), fufuzani ngati chingwe cha netiweki ndichotseguka;
(2) Onani ngati mtundu wa kugwirizana ukufanana: khadi la maukonde ndi ma routers ndi zipangizo zina zimagwiritsa ntchito zingwe zodutsa, ndipo masiwichi, ma hubs ndi zipangizo zina zimagwiritsa ntchito zingwe zowongoka;
(3) Onani ngati mlingo wa kufala kwa chipangizocho ukufanana.
3. Kutayika kwakukulu kwa paketi ya maukonde
(1) Doko lamagetsi la transceiver silikugwirizana ndi mawonekedwe a chipangizo cha netiweki, kapena mawonekedwe a duplex a mawonekedwe a chipangizo kumapeto onse awiri;
(2) Ngati pali vuto ndi awiri opotoka ndi mutu wa RJ-45, yang'anani;
(3) Mavuto okhudzana ndi kuwala kwa fiber, kaya jumper ikugwirizana ndi mawonekedwe a chipangizo, kaya pigtail ikufanana ndi jumper ndi mtundu wa coupler, ndi zina zotero;
(4) Kaya kutayika kwa mzere wa optical fiber kumaposa kuvomereza kuvomereza kwa zipangizo.
4. Pambuyo pa transceiver ya optical fiber ikugwirizana, mapeto awiriwa sangathe kulankhulana
(1) Ulusi wa kuwala umasinthidwa, ndipo ulusi wa kuwala womwe umagwirizanitsidwa ndi TX ndi RX umasinthidwa;
(2) Kugwirizana pakati pa mawonekedwe a RJ45 ndi chipangizo chakunja sikulakwa (tcherani khutu ku njira yowongoka ndi splicing) ndi mawonekedwe a fiber optical (ceramic ferrule) sagwirizana.Cholakwika ichi chikuwonetsedwa makamaka mu transceiver ya 100M yokhala ndi optoelectronic mutual control function, monga APC ferrule.Ngati pigtail ikugwirizana ndi transceiver ya ferrule ya PC, sichitha kuyankhulana bwino, koma sichidzakhudza kugwirizana kwa transceiver yosagwirizana ndi magetsi.
5. Chochitika chotsegula ndi chotseka
(1) Zitha kukhala kuti njira yochepetsera kuwala ndi yayikulu kwambiri.Panthawiyi, mita yamagetsi yamagetsi ingagwiritsidwe ntchito kuyesa mphamvu ya kuwala kwa mapeto olandira.Ngati ili pafupi ndi mtundu wolandila, imatha kuonedwa ngati kulephera kwa njira mkati mwa 1-2dB;
(2) Zitha kukhala kuti chosinthira cholumikizidwa ndi transceiver ndicholakwika.Panthawiyi, sinthani kusinthana ndi PC, ndiko kuti, ma transceivers awiriwa amalumikizidwa mwachindunji ndi PC, ndipo malekezero awiriwa ali ndi pinged.Kulakwitsa;
(3) Transceiver ikhoza kukhala yolakwika.Panthawiyi, mutha kulumikiza malekezero onse a transceiver ku PC (osati kudzera pa switch).Pambuyo pa mapeto awiriwa alibe vuto ndi PING, tumizani fayilo yaikulu (100M) kuchokera kumapeto mpaka kumapeto.Yang'anani kuthamanga kwake, monga pang'onopang'ono (kutumiza mafayilo pansi pa 200M kwa mphindi zoposa 15), akhoza kuweruzidwa ngati kulephera kwa transceiver.
6. Pambuyo pakuwonongeka ndikuyambiranso, idzabwerera mwakale
Chodabwitsa ichi nthawi zambiri chimayamba chifukwa cha kusintha.Kusinthaku kudzachita kuzindikira zolakwika za CRC ndikuwunika kutalika kwa data yonse yolandilidwa.Mapaketi okhala ndi zolakwika adzatayidwa, ndipo mapaketi olondola adzatumizidwa.
Komabe, mapaketi ena olakwika munjira iyi sangawonekere pakuzindikira zolakwika za CRC ndikutsimikizira kutalika.Mapaketi oterowo sadzatumizidwa kapena kutayidwa panthawi yotumiza, ndipo adzaunjikana mu buffer yosinthika.(buffer), sichingatumizidwe konse.Buffer ikadzadza, ipangitsa kuti chosinthiracho chiwonongeke.Chifukwa panthawiyi kuyambitsanso transceiver kapena kuyambitsanso kusinthana kungapangitse kulankhulana kubwerera mwakale.
