Ma fiber optic transceivers nthawi zambiri amagwiritsidwa ntchito pamalo enieni amtaneti pomwe zingwe za Efaneti sizingathe kubisala ndipo zimayenera kugwiritsa ntchito ulusi wa kuwala kuti atalikitse mtunda wotumizira. Nthawi zambiri amakhala pamalo olumikizirana ndi ma network a Broadband metropolitan area, ndipo amagwiritsidwa ntchito kwambiri pama projekiti osiyanasiyana owunikira ndi chitetezo. Koma mosakayikira tidzakumana ndi mavuto pogwiritsa ntchito ma transceivers a fiber optic, ndiye tingathane bwanji titakumana ndi vutoli.
Kulephera kofala ndi njira zothetsera ma transceivers optical fiber
1. Ndi kugwirizana kotani komwe kumagwiritsidwa ntchito pamene doko la transceiver RJ45 likugwirizana ndi zipangizo zina?
Chifukwa: Doko la RJ45 la transceiver limalumikizidwa ndi netiweki ya PC (DTE data terminal zida) pogwiritsa ntchito zopindika, ndi HUB kapenaSINTHA(DCE data communication equipment) imagwiritsidwa ntchito pamizere yofananira.
2. Chifukwa chiyani kuwala kwa TxLink kuzimitsidwa?
Zifukwa: a. Lumikizani zopotoka molakwika; b. Kulumikizana koyipa pakati pa mutu wopotoka wa kristalo ndi chipangizocho, kapena mtundu wopindika wokha; c. Chipangizocho sichimalumikizidwa bwino.
3. Nchifukwa chiyani kuwala kwa TxLink sikuthwanima koma kumakhalabe kuwala pambuyo poti chingwecho chilumikizidwa bwino?
Phokoso loyambirira: a. Cholakwacho nthawi zambiri chimayamba chifukwa cha mtunda wautali wotumizira; b. Kugwirizana ndi netiweki khadi (yolumikizidwa ndi PC).
4. Chifukwa chiyani kuwala kwa Fxlink kuzimitsidwa?
Zifukwa: a. Chingwe cha fiber sichimalumikizidwa molakwika. Njira yolumikizira yolondola ndi TX-RX, RX-TX kapena fiber mode ndiyolakwika; b. Mtunda wotumizira ndi wautali kwambiri kapena kutayika kwapakati kumakhala kwakukulu, kupitilira kutayika mwadzina kwa mankhwalawa. Yankho lake ndi: Chitanipo kanthu kuti muchepetse kutaya kwapakati kapena m'malo mwake ndi mtunda wautali wotumizira; c. Kutentha kwa ntchito ya optical fiber transceiver ndikokwera kwambiri.
5. Nchifukwa chiyani kuwala kwa Fxlink sikuthwanima koma kumakhalabe pambuyo poti fiber ilumikizidwa bwino?
Choyambitsa: Vutoli limayamba chifukwa mtunda wotumizira ndi wautali kwambiri kapena kutaya kwapakati kumakhala kwakukulu, kupitilira kutayika mwadzina kwa mankhwalawa. Yankho lake ndikuchepetsa kutayika kwapakati kapena m'malo mwake ndi transceiver yotalikirapo yotumizira.
6. Nditani ngati nyali zisanu zonse zayatsidwa kapena chizindikirocho chili chabwinobwino koma sichingathe kufalikira?
Chifukwa: Nthawi zambiri, thimitsani ndikuyambiranso kuti mubwezeretse bwino.
7. Kodi kutentha kozungulira kwa transceiver ndi kotani?
Chifukwa: Optical fiber module imakhudzidwa kwambiri ndi kutentha kozungulira. Ngakhale ili ndi gawo lodzipangira lodziwikiratu, kutentha kumapitilira muyeso wina, mphamvu ya optical ya module ya optical imakhudzidwa ndikuchepetsedwa, potero imafooketsa mphamvu ya chizindikiro cha optical network ndikupangitsa kutayika kwa paketi. ulalo wa kuwala; (nthawi zambiri kutentha kwa optical fiber module kumatha kufika 70 ℃)
8. Kodi kugwirizana ndi mgwirizano wa chipangizo chakunja ndi chiyani?
Chifukwa: 10 / 100M fiber transceivers ali ndi zoletsa zofanana ndi 10/100Mmasiwichi, kawirikawiri osapitirira 1522B kapena 1536B. Pamene akusinthayolumikizidwa ku ofesi yapakati imathandizira ma protocol ena apadera (monga Ciss 'ISL) Paketi yapaketi imachulukitsidwa (Ciss ISL paketi pamwamba ndi 30Bytes), yomwe imaposa malire apamwamba a kutalika kwa chimango cha transceiver ya fiber ndipo imatayidwa nayo, ikuwonetsera. kutayika kwa paketi kwapamwamba kapena kosapambana. Panthawiyi, MTU ya chipangizo chogwiritsira ntchito chiyenera kusinthidwa Mu gawo lotumizira, IP paketi yapamwamba ya IP ndi 18 bytes, ndipo MTU ndi 1500 bytes. Pakalipano, opanga zida zoyankhulirana zapamwamba ali ndi ma protocol amkati. Nthawi zambiri, njira yosiyana ya paketi imagwiritsidwa ntchito kukulitsa paketi ya IP pamwamba. Ngati deta ndi 1500 mabayiti Pambuyo IP paketi, kukula kwa IP paketi upambana 18 ndi kutayidwa), kotero kuti kukula kwa paketi opatsirana pa mzere ndi zokhutiritsa kwa malire chipangizo maukonde pa chimango kutalika. 1522 mabayiti a mapaketi amawonjezeredwa VLANtag.
9. Pamene galimotoyo yakhala ikugwira ntchito kwa nthawi ndithu, n’chifukwa chiyani makhadi ena amalephera kugwira ntchito bwino?
Chifukwa: magetsi oyambilira a chassis amatengera njira yolumikizirana. Kusakwanira kwa malire amagetsi ndi kutayika kwa mizere yayikulu ndizovuta zazikulu. Chassis ikagwira ntchito kwa nthawi yayitali, makhadi ena sangathe kugwira ntchito bwino. Makhadi ena akatulutsidwa, makhadi otsalawo amagwira ntchito bwino. Chassis itatha kugwira ntchito kwa nthawi yayitali, cholumikizira makutidwe ndi okosijeni chimayambitsa kutayika kwakukulu kwa cholumikizira. Mphamvu yamagetsi iyi imagwera kuposa malamulo. Kusiyanasiyana kofunikira kungapangitse khadi la chassis kukhala lachilendo. Ma diode amphamvu kwambiri a Schottky amagwiritsidwa ntchito kudzipatula ndikuteteza mphamvu ya chassiskusintha, kusintha mawonekedwe a cholumikizira, ndi kuchepetsa kutsika kwa magetsi chifukwa cha dera lolamulira ndi cholumikizira. Panthawi imodzimodziyo, kuperewera kwa mphamvu kwa magetsi kumawonjezeka, zomwe zimapangitsa kuti magetsi osungirako asungidwe kukhala abwino komanso otetezeka, ndikupangitsa kuti ikhale yoyenera pazofunikira za nthawi yayitali yosasokonezeka.
10. Kodi ma alarm a ulalo amapereka ntchito zotani pa transceiver?
Chifukwa: Transceiver ili ndi alamu yolumikizira (linkloss). Chingwe chikalumikizidwa, chimangobwerera ku doko lamagetsi (ndiko kuti, chizindikiro chomwe chili padoko lamagetsi chidzatulukanso). Ngati ndikusinthaali ndi kasamalidwe ka netiweki, zidzawonetsedwa kukusinthanthawi yomweyo. Network management software.
