Nigute ushobora kugera kuri kilometero mirongo ya ultra-ndende yohereza?N'amasanduku abiri?Kusanya vuba ingingo zubumenyi!

Iyo bigeze ku ntera ndende, urebye ikiguzi, umushoferi ushaje azabanza gutekereza kubintu bibiri: fibre optique transceivers hamwe nikiraro.Hamwe na fibre optique, koresha transceivers.Niba nta fibre optique ihari, biterwa nuburyo ibidukikije bishobora guhuza ikiraro.
Ibirometero birenga icumi na kilometero mirongo, ariko kandi kugirango tumenye neza kandi byizewe, fibre optique ni ngombwa.
Uyu munsi, reka tuvuge igisubizo cyambere mugutumanaho kwa fibre optique - optique fibre transceiver.
Transceiver ni igikoresho cyo guhindura ibimenyetso, mubisanzwe byitwa fibre optique.Kugaragara kwa fibre optique ihinduranya ibyuma byamashanyarazi bigoretse hamwe nibimenyetso bya optique kuri buriwese, bigatuma ihererekanyabubasha ryuzuye ryapaki yamakuru hagati yimiyoboro yombi, kandi mugihe kimwe no kwagura intera yohereza imiyoboro kuva kuri metero 100 zinsinga zumuringa kugeza 100 kilometero (fibre yuburyo bumwe).
Hamwe niterambere rihoraho ryikoranabuhanga, ryahindutse icyerekezo kigezweho ko tekinoroji yihuta ya serivise ya VO isimbuza tekinoroji gakondo I / O.Umuvuduko wa bisi yihuta cyane ni 133 MB / s ya ATA7.Igipimo cyo kohereza cyatanzwe na SATA1.0 cyashyizwe ahagaragara mu 2003 cyageze kuri MB / s 150, naho umuvuduko wa theoretical ya SATA3.0 wageze kuri 600 MB / s.Iyo igikoresho gikora ku muvuduko mwinshi, bisi ibangikanye irashobora guhungabana no kunyura, bigatuma insinga zigoye cyane.Gukoresha seriveri ya seriveri irashobora koroshya igishushanyo mbonera no kugabanya umubare wabahuza.Imigaragarire ya seriyeri nayo ikoresha imbaraga nke ugereranije nicyambu kibangikanye na bisi imwe.Kandi uburyo bwakazi bwigikoresho bwahinduwe buva muburyo bwoherejwe bwoherejwe, kandi umuvuduko wikurikiranya urashobora gukuba kabiri uko inshuro ziyongera.
FPGA ishingiye kuri Gb yihuta urwego hamwe nubushobozi buke bwububiko, ituma abashushanya gukoresha ibikoresho bya EDA neza kugirango bakemure vuba ikibazo cya protocole nimpinduka zihuse.Hamwe nogukoresha kwinshi kwa FPGA, transceiver yinjijwe muri FPGA, ibaye inzira nziza yo gukemura ikibazo cyumuvuduko wo kohereza ibikoresho.
Umuvuduko wihuse utuma bishoboka kohereza umubare munini wamakuru-ku-ngingo.Ubu buryo bwitumanaho bwitumanaho bukoresha byimazeyo ubushobozi bwumuyoboro wogukwirakwiza kandi bugabanya umubare wimiyoboro isabwa hamwe na pine yibikoresho ugereranije na bisi zibangikanye, bityo bikagabanya cyane itumanaho.igiciro.Transceiver ifite imikorere myiza igomba kugira ibyiza byo gukoresha ingufu nke, ingano nto, iboneza ryoroshye, hamwe nubushobozi buhanitse, kuburyo ishobora kwinjizwa byoroshye muri sisitemu ya bisi.Mumuvuduko wihuse wuruhererekane rwamakuru yoherejwe, imikorere ya transceiver igira uruhare rukomeye mugukwirakwiza kwimodoka ya bisi, kandi ikagira ingaruka no kumikorere ya sisitemu ya bisi kurwego runaka.Ubu bushakashatsi burasesengura ishyirwa mu bikorwa ryihuta ryihuta ryimyanya ndangagitsina kuri platform ya FPGA, kandi rikanatanga ibisobanuro byingirakamaro mugushira mubikorwa protocole zitandukanye yihuta.
Aka gasanduku gato gafite umuvuduko mwinshi cyane muri gahunda yo kohereza intera ndende, kandi irashobora kugaragara mugukurikirana kwacu, kutagira umugozi, fibre optique hamwe nibindi bintu.
uburyo bwo gukoresha
Amashanyarazi ya fibre optique akoreshwa muburyo bubiri, kandi agashyirwa kumurongo wanyuma (ushobora guhuzwa na terefone nka kamera, AP, na PC ukoresheje sisitemu) hamwe no kwakira kure (nkicyumba cya mudasobwa / icyumba cyo kugenzura hagati, nibindi ., byanze bikunze, irashobora kandi gukoreshwa muburyo bwo kugera.
Ihame, mugihe cyose ibisobanuro bya tekiniki nkigipimo, uburebure bwumurongo, ubwoko bwa fibre (nkibicuruzwa bimwe-byonyine biva mu bicuruzwa, cyangwa uburyo bumwe bumwe bwa fibre fibre) birahuye, ibirango bitandukanye birahuye, ndetse ndetse impera imwe ya fibre transceiver hamwe numutwe umwe wa optique module irashobora kugerwaho.itumanaho.Ariko ntabwo tubishimangira.
Fibre imwe
Transceiver imwe ya fibre ikoresha tekinoroji ya WDM (diviziyo yuburebure bwa multiplexing), impera imwe yohereza uburebure bwa 1550nm, yakira uburebure bwa 1310nm, naho iyindi ikohereza 1310nm ikakira 1550nm, kugirango tumenye amakuru yakira no kohereza kuri fibre optique.
Kubwibyo, hari icyambu kimwe gusa kuri ubu bwoko bwa transceiver, kandi impera zombi zirasa neza.Kugirango dutandukanye, ibicuruzwa bigaragazwa muri rusange na A na B.
Transceiver imwe ya fibre imwe (ku ishusho ni couple, zeru imwe)
Ibyambu bya optique ya transibiri ya fibre fibre ni "couple imwe" - icyambu cyohereza cyanditswemo na TX + icyambu cyakira cyaranzwe na RX, impera imwe ni couple, kandi buri kohereza no kwakira akora imirimo ashinzwe.Uburebure bwa TX na RX burasa, byombi ni 1310nm.
Transibiri ya fibre-fibre (ku ishusho ni couple, zeru imwe)
Kugeza ubu, ibicuruzwa nyamukuru bya fibre imwe ku isoko.Kubijyanye nubushobozi bwogukwirakwiza bugereranywa, transibers ya fibre imwe "ikiza ikiguzi cya fibre imwe" biragaragara ko ikunzwe cyane.

Singlemode na Multimode
Itandukaniro riri hagati yuburyo bumwe bwa optique ya fibre transibers hamwe nuburyo bwinshi bwa optique ya fibre transibre biroroshye, ni ukuvuga, itandukaniro riri hagati yuburyo bumwe bwa optique na fibre optique.
Intangiriro ya diameter ya fibre imwe ya fibre ni nto (uburyo bumwe gusa bwurumuri rwemerewe gukwirakwizwa), gutatanya ni bito, kandi birwanya kwivanga.Intera yoherejwe irenze cyane iy'ubwoko bwinshi bwa fibre, ishobora kugera kuri kilometero zirenga 20 cyangwa se kilometero amagana.Mubisanzwe ushyirwa muri kilometero 2.
Nibyo rwose kubera ko diameter yibanze ya fibre yuburyo bumwe ari ntoya, urumuri rugoye kugenzura, kandi lazeri ihenze cyane irasabwa nkisoko yumucyo (fibre yuburyo bwinshi ikoresha LED itanga isoko), igiciro rero hejuru kurenza iyo fibre-moderi nyinshi, ikaba ihenze cyane.
Kugeza ubu, hari ibicuruzwa byinshi byerekana uburyo bumwe bwohereza ibicuruzwa ku isoko.Porogaramu yuburyo bwinshi bwimikorere ni byinshi, ibikoresho byibanze kubikoresho byingenzi, intera ngufi nini-itumanaho.
ibintu bitatu by'ingenzi
1. Umuvuduko.Hano hari ibicuruzwa byihuse na Gigabit birahari.
2. Intera yoherejwe.Hano hari ibicuruzwa bya kilometero nyinshi na kilometero mirongo.Usibye intera iri hagati yimpera zombi (intera ya optique ya kabili), ntukibagirwe kureba intera kuva ku cyambu cyamashanyarazi kugera kuri switch.Mugufi ni byiza.
3. Ubwoko bwa fibre.Uburyo bumwe cyangwa uburyo bwinshi, fibre imwe cyangwa fibre nyinshi.
