I-DCI ye-Architecture eqhelekileyo kunye neChain yeShishini

Kutshanje, iqhutywa kuphuhliso lwetekhnoloji ye-AI kuMntla Melika, imfuno yoqhagamshelo phakathi kweendawo ze-arithmetic network ikhule kakhulu, kwaye iteknoloji ye-DCI edibeneyo kunye neemveliso ezinxulumeneyo ziye zatsala ingqalelo kwimarike, ngakumbi kwimarike yemali.

I-DCI (i-Data Centre Interconnect, okanye i-DCI ngokufutshane), okanye i-Data Centre Interconnect, kukudibanisa amaziko ahlukeneyo edatha ukuphumeza ukwabelana ngezibonelelo, ukusetyenzwa kwedatha ye-cross-domain kunye nokugcinwa. Xa ukwakhiwa izisombululo DCI, hayi kuphela kufuneka ukuba uqwalasele imfuneko uqhagamshelo bandwidth, kodwa kwakhona imfuneko lula kunye nokusebenza olukrelekrele kunye nokugcinwa, ngoko bhetyebhetye kwaye ulwakhiwo womnatha olufanelekileyo iye yaba ngundoqo DCI zokwakhiwa.DCI iimeko isicelo zahlulwe zibe iintlobo ezimbini: i-DCI ye-metro kunye ne-DCI yomgama omde, kwaye ugqaliselo apha lusekuxoxweni ngemarike ye-DCI yemetro.

I-DCI-BOX sisizukulwana esitsha sabaqhubi be-telecom kuyilo lwenethiwekhi ye-metropolitan, abaqhubi balindele ukukwazi ukwenza i-optoelectronic decoupling, kulula ukuyilawula, ngoko ke i-DCI-BOX yaziwa ngokuba yi-open decoupled optical network.

Amacandelo ayo e-hardware angundoqo abandakanya: izixhobo zokuhambisa ulwahlulo lwamaza, iimodyuli ze-optical, iifibers optical kunye nezinye izixhobo ezinxulumene nazo. Phakathi kwabo:

I-DCI wavelength transmission izixhobo: ngokuqhelekileyo yahlulahlulwe kwiimveliso umaleko zombane, iimveliso umaleko optical kunye neemveliso optical-electrical hybrid, yeyona mveliso iphambili data data interconnection, equlathe racks, icala line kunye necala umthengi. Icala lomgca libhekiselele kumqondiso ojongene necala lokuhambisa ifayibha, kwaye icala lomthengi libhekiselele kumqondiso ojongene necala lokutshintsha.

Iimodyuli ze-Optical: ngokuqhelekileyo ziquka iimodyuli ze-optical, iimodyuli ze-optical ezihambelanayo, njl., umyinge weemodyuli ze-optical ezingaphezu kwe-40 kufuneka zifakwe kwisixhobo sokudlulisa, izinga eliqhelekileyo lokuxhamla kweziko ledatha kwi-100Gbps, 400Gbps, kwaye ngoku kwilingo. Inqanaba lenqanaba le-800Gbps.

I-MUX / DEMUX: Uluhlu lweempawu ze-optical carrier ze-wavelengths ezahlukeneyo ezithwele ulwazi oluhlukeneyo zidityaniswe kunye kwaye zidibaniswe kwi-fiber optical efanayo yokudluliselwa ekupheleni kokudlulisa nge-MUX (Multiplexer), kunye nezibonakaliso ze-optical ze-wavelengths ezahlukeneyo ziyahlukana. isiphelo sokufumana ngeDemultiplexer (Demultiplexer).

I-chip ye-AWG: I-DCI edibeneyo yokuhlukanisa i-MUX / DEMUX ehamba phambili isebenzisa inkqubo ye-AWG ukuphumeza.

I-Erbium Doped Fiber AmplifierEDFA: Isixhobo esandisa ubunzulu bophawu olubuthathaka lwe-optical input ngaphandle kokuluguqula lube ngumqondiso wombane.

I-Wavelength Selection Switch WSS: Ukhetho oluchanekileyo kunye nokucwangciswa okuguquguqukayo kwe-wavelength yezibonakaliso ze-optical kufezekiswa ngesakhiwo esichanekileyo se-optical kunye nokulawula indlela.

IModyuli yokuJonga iNethiwekhi ye-OCM kunye ne-OTDR: ye-DCI yokuhlola umgangatho womsebenzi wothungelwano kunye nokugcinwa. I-Optical Communication Channel Monitor i-OCPM, i-OCM, i-OPM, i-Optical Time Domain Reflectometer i-OTDR isetyenziselwa ukulinganisa i-fiber attenuation, ukulahleka kwe-connector, indawo ye-fiber fault point kunye nokuqonda ukusabalalisa ukulahleka kobude befiber.

I-Optical Fiber Line Auto Switch Protection Equipment (OLP): Ukutshintshela ngokuzenzekelayo kwifiber yokugcina i-fiber xa i-fiber engundoqo ihluleka ukunika ukhuseleko oluninzi lwenkonzo.

Intambo yeFayibha ye-Optical: Indawo yokuhanjiswa kwedatha phakathi kwamaziko edatha.

Ngokukhula okuqhubekayo kwe-traffic, inani ledatha eliqhutywe liziko ledatha enye, inani leshishini lilinganiselwe, i-DCI inokuphucula ngcono izinga lokusetyenziswa kweziko ledatha, ngokuthe ngcembe ibe yinto engenakuphepheka ekuphuhliseni amaziko edatha, kwaye imfuno iya kukhula. Ngokutsho kwewebhusayithi esemthethweni yeCiena, uMntla Melika ngoku yeyona marike iphambili ye-DCI, kwaye kuqikelelwa ukuba ummandla waseAsia-Pacific uya kungena kwinqanaba eliphezulu lophuhliso kwixesha elizayo.
