Uyilo oluQhelekileyo lweDCI kunye neCandelo leShishini

Kutshanje, ngenxa yophuhliso lwetekhnoloji ye-AI eMntla Melika, imfuno yokunxibelelana phakathi kwama-nodes enethiwekhi yezibalo ikhule kakhulu, kwaye itekhnoloji ye-DCI edibeneyo kunye neemveliso ezinxulumene nayo zitsale ingqalelo kwimarike, ngakumbi kwimarike yemali.

I-DCI (Data Center Interconnect, okanye i-DCI ngamafutshane), okanye i-Data Center Interconnect, kukudibanisa amaziko edatha ahlukeneyo ukuze kufezekiswe ukwabelana ngezixhobo, ukucutshungulwa kwedatha kunye nokugcinwa kwayo. Xa usakha izisombululo ze-DCI, akufuneki nje kuphela ukuba uqwalasele imfuneko ye-bandwidth yoqhagamshelo, kodwa kunye nesidingo sokusebenza okulula nokukrelekrele kunye nokugcinwa, ngoko ke ukwakhiwa kwenethiwekhi eguquguqukayo nelula kuye kwaba ngundoqo wokwakhiwa kwe-DCI. Iimeko zesicelo se-DCI zahlulwe zibe ziintlobo ezimbini: i-metro DCI kunye ne-DCI yomgama omde, kwaye ingqwalasela apha ikukuthetha ngemarike ye-metro DCI.

I-DCI-BOX sisizukulwana esitsha sabaqhubi be-telecom bokwakha inethiwekhi yesixeko, abaqhubi balindele ukuba bakwazi ukwenza i-optoelectronic decoupling, kulula ukuyilawula, ngoko ke i-DCI-BOX ikwaziwa njengenethiwekhi ye-open decoupled optical.

Izinto eziphambili zehardware yayo ziquka: izixhobo zokudlulisa ubude be-wavelength, iimodyuli ze-optical, iifayibha ze-optical kunye nezinye izixhobo ezinxulumene noko. Phakathi kwazo:

Izixhobo zokudlulisa ubude bexesha le-DCI: zihlala zahlulwe zibe ziimveliso zombane, iimveliso zombane kunye neemveliso zombane ezixutyiweyo, yimveliso ephambili yokunxibelelana kweziko ledatha, equka iirakhi, icala lomgca kunye necala lomthengi. Icala lomgca libhekisa kwisignali ejongene necala lefayibha yokudlulisa, kwaye icala lomthengi libhekisa kwisignali ejongene necala le-switch docking.

Iimodyuli ze-Optical: zihlala ziquka iimodyuli ze-optical, iimodyuli ze-coherent optical, njl.njl., umyinge weemodyuli ze-optical ezingaphezu kwama-40 kufuneka zifakwe kwisixhobo sokudlulisa, izinga eliqhelekileyo lokunxibelelana kweziko ledatha kwi-100Gbps, 400Gbps, kwaye ngoku kwinqanaba lovavanyo lezinga le-800Gbps.

I-MUX/DEMUX: Uthotho lwemiqondiso yokuthwala i-optical yee-wavelengths ezahlukeneyo ezithwala ulwazi olwahlukeneyo zidityaniswe kunye kwaye zidityaniswe kwi-optical fiber efanayo yokudlulisela kwisiphelo sokudlulisa nge-MUX (Multiplexer), kwaye imiqondiso yokukhanya yee-wavelengths ezahlukeneyo zahlulwe kwisiphelo sokwamkela nge-Demultiplexer (Demultiplexer).

Itshiphusi ye-AWG: I-DCI edibeneyo yokwahlulahlula i-MUX/DEMUX eqhelekileyo isebenzisa inkqubo ye-AWG ukufezekisa.

Isandisi seFiber esifakwe i-Erbium DopedI-EDFA: Isixhobo esandisa amandla esignali ye-optical engenayo ebuthathaka ngaphandle kokuyiguqula ibe sisignali yombane.

I-WSS yoKhetho lweWavelength: Ukhetho oluchanekileyo kunye nohlengahlengiso oluguquguqukayo lwe-wavelength yezibonakaliso ze-optical lufezekiswa ngesakhiwo esichanekileyo se-optical kunye nendlela yokulawula.

I-Optical Network Monitoring Module OCM kunye ne-OTDR: yokujonga nokugcina umgangatho wokusebenza kwenethiwekhi ye-DCI. I-Optical Communication Channel Monitor OCPM, OCM, OPM, i-Optical Time Domain Reflectometer OTDR zisetyenziselwa ukulinganisa ukuncitshiswa kwefayibha, ukulahleka kwesixhumi, indawo yefayibha kunye nokuqonda ukusasazwa kokulahleka kobude befayibha.

Izixhobo zoKhuselo oluZisebenzelayo zeFiber Line yeOptical (OLP): Tshintshela ngokuzenzekelayo kwifayibha yogcino xa ifayibha ephambili ingaphumeleli ukubonelela ngokhuseleko oluninzi kwinkonzo.

Intambo yeFiber yeOptical: Indlela yokudlulisa idatha phakathi kwamaziko edatha.

Ngokukhula okuqhubekayo kwezithuthi, ubungakanani bedatha ethwalwa liziko ledatha elinye, ubungakanani beshishini bulinganiselwe, i-DCI inokuphucula ngcono izinga lokusetyenziswa kweziko ledatha, iye yaba ngumkhwa ongenakuphepheka ekuphuhlisweni kwamaziko edatha, kwaye imfuno iya kukhula. Ngokutsho kwewebhusayithi esemthethweni yeCiena, uMntla Melika okwangoku yimarike ephambili ye-DCI, kwaye kuqikelelwa ukuba ummandla we-Asia-Pacific uza kungena kwizinga eliphezulu lophuhliso kwixesha elizayo.
