Pakumanga maukonde ndi kugwiritsa ntchito, popeza mtunda wotalikirapo wa chingwe cha netiweki nthawi zambiri ndi 100 metres, ndikofunikira kugwiritsa ntchito zida zolumikizirana monga ma transceivers optical fiber potumiza maukonde akutali.Optical fiber transceiversNthawi zambiri amagwiritsidwa ntchito m'malo opangira maukonde pomwe zingwe za Efaneti sizingathe kuphimba ndipo ulusi wa kuwala uyenera kugwiritsidwa ntchito kukulitsa mtunda wotumizira. Ndiye, ndi chiyani chomwe chiyenera kutsatiridwa mukamagwiritsa ntchito ma fiber optic transceivers?

1. Kulumikizana kwa mawonekedwe a fiber optical kuyenera kumvetsera ku single-mode ndi multimode yofananira: ma transceivers amtundu umodzi amatha kugwira ntchito pansi pa fiber single-mode ndi multi-mode fiber, koma ma transceivers amtundu wamitundu yambiri sangathe kugwira ntchito pansi pa njira imodzi. fiber. Katswiriyo adanena kuti zida zamtundu umodzi zitha kugwiritsidwa ntchito ndi ma multi-mode fiber pomwe mtunda wotumizira ma fiber optical uli waufupi, koma katswiriyo amalimbikitsabe kuti m'malo mwake asinthe ndi cholumikizira chofananira cha fiber momwe angathere, kuti zida zitha kugwira ntchito zambiri. mokhazikika komanso modalirika. Kutayika kwa paketi.

2. Kusiyanitsa zida za fiber imodzi ndi ziwiri-ziwiri: doko la transmitter (TX) la transceiver kumapeto kwa chipangizo chapawiri-fiber chimagwirizanitsidwa ndi doko lolandira (RX) la transceiver pamapeto ena. Poyerekeza ndi zida zamitundu iwiri, zida zamtundu umodzi zitha kupewa vuto la kuyika kolakwika kwa doko la transmitter (TX) ndi doko lolandila (RX) mukamagwiritsa ntchito. Chifukwa ndi transceiver ya fiber imodzi, doko limodzi lokha la kuwala ndi TX ndi RX panthawi imodzimodzi, ndipo mawonekedwe a mawonekedwe a SC akhoza kulumikizidwa, omwe ndi osavuta kugwiritsa ntchito. Kuphatikiza apo, zida zamtundu umodzi zitha kupulumutsa kugwiritsa ntchito ulusi ndikuchepetsa bwino mtengo wonse wazowunikira.

3. Samalani kudalirika ndi kutentha kozungulira kwa zida za optical fiber transceiver: optical fiber transceiver yokha idzatulutsa kutentha kwakukulu pamene ikugwiritsidwa ntchito, ndipo transceiver ya optical fiber sichidzagwira ntchito bwino pamene kutentha kuli kwakukulu. Chifukwa chake, kuchuluka kwa kutentha kwa magwiridwe antchito mosakayika kungachepetse kuthekera kwa kulephera kosayembekezereka kwa zida zomwe zimafunikira kuthamanga kwa nthawi yayitali, ndipo kudalirika kwazinthuzo ndikwambiri. Makamera ambiri akutsogolo achitetezo chachitetezo cha mphezi amayikidwa panja panja, ndipo chiwopsezo cha kuwonongeka kwa mphezi kwa zida kapena zingwe ndizokwera kwambiri. Kuphatikiza apo, imakhudzidwanso kwambiri ndi kusokonezedwa ndi ma elekitiroma monga kuphatikizika kwa mphezi, kuchulukitsitsa kwamagetsi, kutulutsa ma electrostatic, ndi zina zambiri, zomwe zimatha kuwononga zida, ndipo zikavuta kwambiri zimatha kupangitsa kuti dongosolo lonse loyang'anira liyimitsidwe.

4. Kaya amathandizira full-duplex ndi theka-duplex: Ma transceivers ena a fiber optic pamsika amatha kugwiritsa ntchito malo okhala ndi duplex ndipo sangathe kuthandizira theka-duplex, monga kulumikiza ku mitundu ina ya ma switch kapena hubs, ndipo amagwiritsa ntchito theka- duplex mode , idzayambitsa mikangano yayikulu komanso kutayika kwa paketi.
