I-DCI Typical Architecture and Industry Chain

Muva nje, eqhutshwa ukuthuthukiswa kobuchwepheshe be-AI eNyakatho Melika, isidingo sokuxhumanisa phakathi kwama-node enethiwekhi ye-arithmetic sikhule kakhulu, futhi ubuchwepheshe obuxhumene ne-DCI nemikhiqizo ehlobene budonse ukunaka emakethe, ikakhulukazi emakethe yemali.

I-DCI (I-Data Center Interconnect, noma i-DCI ngamafuphi), noma i-Data Center Interconnect, iwukuxhuma izikhungo zedatha ezihlukene ukuze kuzuzwe ukwabelana ngezinsiza, ukucutshungulwa kwedatha yesizinda kanye nokugcinwa. Lapho wakha izixazululo ze-DCI, awudingi nje kuphela ukucabangela isidingo somkhawulokudonsa wokuxhuma, kodwa futhi nesidingo sokusebenza nokugcinwa okulula nokuhlakaniphile, ngakho ukwakhiwa kwenethiwekhi okuguquguqukayo nokulula sekube umgogodla wokwakhiwa kwe-DCI.Izimo zohlelo lokusebenza ze-DCI zihlukaniswe zaba izinhlobo ezimbili: i-DCI kamasipala kanye ne-DCI yamabanga amade, futhi okugxilwe kukho ukuxoxa ngemakethe kamasipala we-DCI.

I-DCI-BOX iyisizukulwane esisha sama-telecom opharetha ekwakhiweni kwenethiwekhi yedolobha elikhulu, opharetha balindele ukukwazi ukwenza i-optoelectronic decoupling, kulula ukuyilawula, ngakho-ke i-DCI-BOX yaziwa nangokuthi inethiwekhi ye-optical evulekile ye-decoupled.

Izingxenye zayo eziyinhloko ze-hardware zihlanganisa: imishini yokudlulisa i-wavelength division, amamojula optical, ama-optical fibers namanye amadivaysi ahlobene. Phakathi kwazo:

Imishini yokudlulisa i-DCI wavelength division: ngokuvamile ihlukaniswa ngemikhiqizo yongqimba kagesi, imikhiqizo ye-optical layer kanye nemikhiqizo ehlanganisiwe ye-optical-electrical, ingumkhiqizo oyinhloko wokuxhumanisa isikhungo sedatha, ohlanganisa ama-rack, uhlangothi lomugqa kanye nohlangothi lwamakhasimende. Uhlangothi lomugqa lubhekisela esignali ebheke ohlangothini lwefayibha yokudlulisela, futhi uhlangothi lwekhasimende lubhekisela kusiginali ebheke ohlangothini lokudokha lweswishi.

Amamojula we-Optical: ngokuvamile ahlanganisa amamojula optical, amamojula ahlangene optical, njll., isilinganiso samamojula we-optical angaphezu kuka-40 adinga ukufakwa kudivayisi yokudlulisela, izinga elijwayelekile lokuxhunywa kwesikhungo sedatha ku-100Gbps, 400Gbps, futhi manje esivivinyweni. isigaba sezinga le-800Gbps.

I-MUX/DEMUX: Uchungechunge lwezimpawu zenkampani ye-optical carrier yamaza ahlukene aphethe ulwazi oluhlukahlukene luhlanganiswa ndawonye futhi luhlanganiswe ku-fiber optical efanayo ukuze idluliselwe ekugcineni kokudlulisela nge-MUX (Multiplexer), futhi amasignali optical amaza ahlukahlukene ahlukene ahlukaniswa isiphetho sokwamukela nge-Demultiplexer (Demultiplexer).

I-chip ye-AWG: I-DCI ehlanganisa isihlukanisi se-MUX/DEMUX evamile kusetshenziswa uhlelo lwe-AWG ukuze kuzuzwe.

I-Erbium Doped Fiber AmplifierEDFA: Idivayisi ekhulisa ukushuba kwesignali ye-optical yokufaka engenamandla ngaphandle kokuyiguqulela isignali kagesi.

I-Wavelength Selection Switch WSS: Ukukhethwa okunembile kanye nokuhlela okuguquguqukayo kobude begagasi bezimpawu ezibonakalayo kubonakala ngesakhiwo esinembile se-optical kanye nendlela yokulawula.

I-Optical Network Monitoring Module OCM kanye ne-OTDR: yokuqapha nokugcinwa kwekhwalithi yokusebenza kwenethiwekhi ye-DCI. I-Optical Communication Channel Monitor i-OCPM, i-OCM, i-OPM, i-Optical Time Domain Reflectometer OTDR isetshenziselwa ukukala ukuncipha kwe-fiber, ukulahlekelwa kwesixhumi, indawo yephutha le-fiber futhi baqonde ukusatshalaliswa kokulahlekelwa kobude be-fiber.

I-Optical Fiber Line Auto Switch Protection Equipment (OLP): Shintshela ngokuzenzakalelayo kwifayibha eyisipele lapho ifayibha eyinhloko yehluleka ukunikeza ukuvikeleka okuningi kwesevisi.

Ikhebula le-Optical Fiber: Indawo yokudlulisa idatha phakathi kwezikhungo zedatha.

Ngokukhula okuqhubekayo kwethrafikhi, inani ledatha eliphathwa isikhungo sedatha esisodwa, inani lebhizinisi lilinganiselwe, i-DCI ingathuthukisa kangcono izinga lokusebenzisa isikhungo sedatha, kancane kancane isiphenduke inkambiso engenakugwenywa ekuthuthukisweni kwezikhungo zedatha, futhi isidingo sizokhula. Ngokusho kwewebhusayithi esemthethweni kaCiena, iNyakatho Melika njengamanje iyimakethe eyinhloko ye-DCI, futhi kubikezelwa ukuthi isifunda sase-Asia-Pacific sizongena ngezinga eliphezulu lentuthuko esikhathini esizayo.
