Pankhani yotumiza mtunda wautali, poganizira za mtengo wake, woyendetsa wakale adzayamba kuganizira zinthu ziwiri: ma transceivers a fiber optic ndi milatho.Ndi fiber Optics, gwiritsani ntchito ma transceivers.Ngati palibe CHIKWANGWANI chamawonedwe, zimatengera ngati chilengedwe chenicheni chingagwirizane ndi mlatho.
Makilomita opitilira khumi ndi ma kilomita angapo, komanso kuti mutsimikizire kufalikira kokhazikika komanso kodalirika, ulusi wa kuwala ndikofunikira.
Lero, tiyeni tikambirane njira yotsogola pakulankhulana kwa fiber optical - optical fiber transceiver.
Transceiver ndi chipangizo chosinthira chizindikiro, chomwe nthawi zambiri chimatchedwa fiber optic transceiver.The zikamera wa kuwala CHIKWANGWANI transceivers otembenuka zokhota pawiri zizindikiro magetsi ndi kuwala chizindikiro kwa wina ndi mzake, kuonetsetsa kufala yosalala mapaketi deta pakati pa maukonde awiri, ndipo nthawi yomweyo kuwonjezera kufala malire mtunda wa maukonde kuchokera 100 mamita mawaya amkuwa kuti 100. Makilomita (Single mode fiber).
Ndi chitukuko chosalekeza chaukadaulo, zakhala zomwe zikuchitika masiku ano kuti ukadaulo wothamanga kwambiri wa VO ulowa m'malo mwaukadaulo wofananira wa I/O.Liwiro la mawonekedwe a basi ndi 133 MB/s wa ATA7.Chiwongola dzanja choperekedwa ndi ndondomeko ya SATA1.0 yomwe inatulutsidwa mu 2003 yafika 150 MB / s, ndipo liwiro la SATA3.0 lafika 600 MB / s.Chidacho chikagwira ntchito mothamanga kwambiri, basi yofananira imatha kusokoneza komanso kuphatikizika, zomwe zimapangitsa waya kukhala wovuta kwambiri.Kugwiritsa ntchito ma serial transceivers kumatha kufewetsa kapangidwe kake ndikuchepetsa kuchuluka kwa zolumikizira.Ma seri interfaces amadyanso mphamvu zochepa kuposa madoko ofananira omwe ali ndi bandwidth yomweyi.Ndipo njira yogwirira ntchito ya chipangizocho imasinthidwa kuchoka ku kufalikira kofanana kupita ku kachilombo ka serial, ndipo liwiro la seriyo likhoza kuwirikiza kawiri pamene mafupipafupi akuwonjezeka.
FPGA-based ophatikizidwa Gb liwiro mlingo ndi otsika mphamvu zomangamanga ubwino, zimathandiza okonza kugwiritsa ntchito bwino EDA zida kuthetsa mwamsanga vuto la protocol ndi liwiro kusintha.Ndi kugwiritsa ntchito kwakukulu kwa FPGA, transceiver imaphatikizidwa mu FPGA, yomwe yakhala njira yabwino yothetsera vuto la liwiro la kutumizira zida.
Ma transceivers othamanga kwambiri amachititsa kuti azitha kutumizira zambiri za data point-to-point.Ukadaulo wolumikiziranawu umagwiritsa ntchito mokwanira mphamvu ya mayendedwe a sing'anga yotumizira ndikuchepetsa kuchuluka kwa mayendedwe ofunikira ndi mapini achipangizo poyerekeza ndi mabasi a data ofanana, potero amachepetsa kulumikizana.mtengo.Transceiver yokhala ndi ntchito yabwino kwambiri iyenera kukhala ndi ubwino wogwiritsira ntchito mphamvu zochepa, kukula kochepa, kusinthika kosavuta, ndi kuwongolera kwakukulu, kotero kuti ikhoza kuphatikizidwa mosavuta mu dongosolo la basi.Mu protocol yothamanga kwambiri yotumizira ma data, ntchito ya transceiver imakhala ndi gawo lofunikira pakutengera mawonekedwe a mabasi, komanso imakhudzanso magwiridwe antchito a mawonekedwe a mabasi pamlingo wina.Kafukufukuyu akuwunika kukwaniritsidwa kwa gawo la transceiver othamanga kwambiri papulatifomu ya FPGA, komanso amapereka chidziwitso chothandiza pakukwaniritsidwa kwa ma protocol osiyanasiyana othamanga kwambiri.
Bokosi laling'onoli lili ndi chiwonetsero chokwera kwambiri pamakina opatsirana mtunda wautali, ndipo nthawi zambiri imatha kuwoneka muzowunikira zathu, opanda zingwe, mawonekedwe a fiber optical ndi zochitika zina.
momwe mungagwiritsire ntchito
Ma transceivers opangira ma fiber nthawi zambiri amagwiritsidwa ntchito pawiri, ndipo amayikidwa pamapeto olowera (omwe amatha kulumikizidwa ndi ma terminals monga makamera, ma AP, ndi ma PC kudzera pa switch) ndi malekezero akutali (monga chipinda cha makompyuta / chipinda chowongolera chapakati, ndi zina zotero. ., inde, itha kugwiritsidwanso ntchito pofikira), potero kumanga mlatho wolumikizirana wocheperako, wothamanga kwambiri komanso wokhazikika pazonse ziwiri.
M'malo mwake, malinga ngati mawonekedwe aukadaulo monga kuchuluka, kutalika kwa mafunde, mtundu wa fiber (monga mtundu womwewo wa single-mode single-fiber, kapena single-mode wapawiri-fiber) ndizogwirizana, mitundu yosiyanasiyana imafananizidwa, ndipo ngakhale mapeto amodzi a fiber transceiver ndi mapeto amodzi a optical module angapezeke.kulankhulana.Koma sitikuzipangira.
Single ndi Dual Fiber
Transceiver ya single-fiber imatenga teknoloji ya WDM (wavelength division multiplexing), mapeto amodzi amatumiza kutalika kwa 1550nm, amalandira kutalika kwa 1310nm, ndipo mapeto ena amatumiza 1310nm ndi kulandira 1550nm, kuti azindikire deta yomwe imalandira ndi kutumiza pa chingwe chimodzi cha kuwala.
Chifukwa chake, pali doko limodzi lokha la kuwala pamtundu uwu wa transceiver, ndipo malekezero awiriwo ndi ofanana.Kuti tisiyanitse, zinthuzo zimadziwika ndi malekezero a A ndi B.
Single fiber transceiver (chithunzichi ndi awiri, ziro imodzi)
Ma doko owoneka bwino a transceiver yapawiri-fiber ndi "awiri awiri" - doko lotumizira lolembedwa ndi TX + doko lolandila lolembedwa ndi RX, malekezero amodzi ndi awiri, ndipo aliyense kutumiza ndi kulandira amachita ntchito zake.Mafunde a TX ndi RX ndi ofanana, onse ndi 1310nm.
Transceiver yamitundu iwiri (chithunzichi ndi awiri, ziro imodzi)
Pakadali pano, zinthu zazikuluzikulu za single-fiber pamsika.Pankhani ya mphamvu zofananira zopatsirana, ma transceivers amtundu umodzi omwe "amapulumutsa mtengo wa fiber imodzi" mwachiwonekere ndi otchuka kwambiri.
Singlemode ndi Multimode
Kusiyanitsa pakati pa single-mode optical fiber transceivers ndi multi-mode optical fiber transceivers ndikosavuta, ndiko kuti, kusiyana pakati pa single-mode optical fiber ndi multi-mode optical fiber.
Chigawo chapakati cha fiber single-mode ndi yaying'ono (njira imodzi yokha ya kuwala imaloledwa kufalikira), kubalalitsidwa kumakhala kochepa, ndipo kumatsutsana kwambiri ndi kusokoneza.Mtunda wopatsirana ndi wapamwamba kwambiri kuposa wa fiber multimode, womwe ungafikire makilomita oposa 20 kapena mazana a kilomita.Amagwiritsidwa ntchito mkati mwa 2 kilomita.
Izi ndichifukwa choti makulidwe apakati a fiber single-mode ndi yaying'ono, mtengowo ndi wovuta kuwongolera, ndipo laser yotsika mtengo imafunikira ngati gwero la kuwala (mitundu yambiri yamitundu yambiri imagwiritsa ntchito gwero la kuwala kwa LED), kotero mtengo wake ndi apamwamba kuposa amitundu yambiri, omwe ndi okwera mtengo.
Pakali pano, pali zinthu zambiri zamtundu umodzi wa transceiver pamsika.Mapulogalamu opangira ma data amitundu yambiri ndi ochulukirapo, zida zoyambira ku zida zoyambira, kulumikizana kwakutali kwa bandwidth yayikulu.
magawo atatu ofunika
1. Liwiro.Pali zinthu za Fast ndi Gigabit zomwe zilipo.
2. Mtunda wotumizira.Pali zinthu za makilomita angapo ndi makilomita ambiri.Kuphatikiza pa mtunda pakati pa malekezero awiri (kutalika kwa chingwe cha kuwala), musaiwale kuyang'ana mtunda kuchokera pa doko lamagetsi kupita ku chosinthira.Wamfupi ndi bwino.
3. Mtundu wamtundu wa fiber.Single-mode kapena multi-mode, single-fiber kapena multi-fiber.
