I-DCI Ukwakhiwa Okujwayelekile kanye Nochungechunge Lwezimboni

Muva nje, ngenxa yentuthuko yobuchwepheshe be-AI eNyakatho Melika, isidingo sokuxhumana phakathi kwama-node enethiwekhi yezibalo sikhule kakhulu, kanti ubuchwepheshe be-DCI obuxhumene nemikhiqizo ehlobene budonsele ukunaka emakethe, ikakhulukazi emakethe yezimali.

I-DCI (i-Data Center Interconnect, noma i-DCI ngamafuphi), noma i-Data Center Interconnect, iwukuxhumanisa izikhungo zedatha ezahlukene ukuze kufezwe ukwabelana ngezinsiza, ukucutshungulwa kwedatha yesizinda esiphakathi kanye nokugcinwa kwayo. Lapho wakha izixazululo ze-DCI, akudingeki nje kuphela ukuthi ucabangele isidingo se-bandwidth yokuxhumeka, kodwa futhi nesidingo sokusebenza okulula nokuhlakaniphile kanye nokugcinwa kwayo, ngakho-ke ukwakhiwa kwenethiwekhi okuguquguqukayo nokulula kuye kwaba yisisekelo sokwakhiwa kwe-DCI. Izimo zesicelo se-DCI zihlukaniswe ngezinhlobo ezimbili: i-metro DCI kanye ne-DCI yebanga elide, futhi ukugxila lapha kungokuxoxa ngemakethe ye-metro DCI.

I-DCI-BOX iyisizukulwane esisha sabasebenzi bezokuxhumana ngobuchwepheshe bokwakha inethiwekhi yedolobha, abaqhubi balindele ukukwazi ukwenza i-optoelectronic decoupling, okulula ukuyilawula, ngakho-ke i-DCI-BOX yaziwa nangokuthi inethiwekhi ye-optical evulekile ehlanganisiwe.

Izingxenye zayo eziyinhloko zehadiwe zifaka: imishini yokudlulisa ukuhlukaniswa kwamaza, amamojula okukhanya, imicu yokukhanya kanye namanye amadivayisi ahlobene. Phakathi kwawo:

Imishini yokudlulisa i-DCI division wavelength: ivame ukuhlukaniswa ngemikhiqizo yezendlalelo zikagesi, imikhiqizo yezendlalelo ze-optical kanye nemikhiqizo ye-optical-electric hybrid, ingumkhiqizo oyinhloko wokuxhumana kwesikhungo sedatha, okuhlanganisa ama-racks, uhlangothi lomugqa kanye nohlangothi lwamakhasimende. Uhlangothi lomugqa lubhekisela esignalini ebheke ohlangothini lwefayibha yokudlulisa, kanti uhlangothi lwamakhasimende lubhekisela esignalini ebheke ohlangothini lwe-switch docking.

Amamojula okubona: ngokuvamile afaka amamojula okubona, amamojula okubona ahambisanayo, njll., isilinganiso samamojula okubona angaphezu kuka-40 adinga ukufakwa kudivayisi yokudlulisa, izinga elijwayelekile lokuxhumana kwesikhungo sedatha ku-100Gbps, 400Gbps, futhi manje esigabeni sokuhlola sezinga le-800Gbps.

I-MUX/DEMUX: Uchungechunge lwezimpawu zokuthwala ukukhanya zamaza ahlukene aphethe ulwazi oluhlukahlukene luhlanganiswa ndawonye futhi luhlanganiswe ku-fiber efanayo yokukhanya ukuze idluliselwe ekugcineni kokudlulisa nge-MUX (Multiplexer), kanti izimpawu zokukhanya zamaza ahlukahlukene zihlukaniswa ekugcineni kokwamukela nge-Demultiplexer (Demultiplexer).

I-chip ye-AWG: I-DCI ehlanganisiwe i-splitter MUX/DEMUX esetshenziswa kakhulu uhlelo lwe-AWG ukuze kufezwe.

I-Amplifier ye-Fiber e-Doped ye-ErbiumI-EDFA: Idivayisi ekhulisa ubukhali besiginali yokukhanya yokufaka ebuthakathaka ngaphandle kokuyiguqula ibe isiginali kagesi.

I-WSS Yokukhetha Ubude Begagasi: Ukukhetha okunembile kanye nokuhlela okuguquguqukayo kobude begagasi lamasignali okubona kutholakala ngesakhiwo esinembile segagasi kanye nendlela yokulawula.

I-Optical Network Monitoring Module OCM kanye ne-OTDR: yokuqapha nokugcina ikhwalithi yokusebenza kwenethiwekhi ye-DCI. I-Optical Communication Channel Monitor OCPM, OCM, OPM, i-Optical Time Domain Reflectometer OTDR isetshenziselwa ukukala ukuncishiswa kwefayibha, ukulahleka kwesixhumi, indawo yephutha lefayibha nokuqonda ukusatshalaliswa kokulahleka kobude befayibha.

Imishini Yokuvikela I-Optical Fiber Line Auto Switch (OLP): Shintshela ngokuzenzakalelayo ku-fiber yokusekelayo lapho i-fiber eyinhloko yehluleka ukunikeza ukuvikelwa okuningi kwensizakalo.

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

Ngokukhula okuqhubekayo kwethrafikhi, inani ledatha elithwalwa yisikhungo sedatha esisodwa, inani lebhizinisi lilinganiselwe, i-DCI ingathuthukisa kangcono izinga lokusetshenziswa kwesikhungo sedatha, kancane kancane ibe yindlela engenakugwenywa ekuthuthukisweni kwezikhungo zedatha, futhi isidingo sizokhula. Ngokusho kwewebhusayithi esemthethweni yeCiena, iNyakatho Melika njengamanje iyimakethe eyinhloko ye-DCI, futhi kubikezelwa ukuthi isifunda sase-Asia-Pacific sizongena ezingeni eliphezulu lentuthuko esikhathini esizayo.
