DCI Typical Architecture uye Indasitiri Chain

Nguva pfupi yadarika, ichitungamirwa nekuvandudzwa kwehunyanzvi hweAI muNorth America, kudiwa kwekubatana pakati penode dze arithmetic network kwakura zvakanyanya, uye yakabatana DCI tekinoroji nezvimwe zvine hukama zvigadzirwa zvakakwezva kutarisa mumusika, kunyanya mumusika mukuru.

DCI (Data Center Interconnect, kana DCI kwenguva pfupi), kana Data Center Interconnect, ndeyekubatanidza nzvimbo dzakasiyana dze data kuti uwane kugovana zviwanikwa, kuyambuka-domain data kugadzirisa uye kuchengetedza. Paunenge uchivaka DCI zvigadziriso, kwete chete iwe unofanirwa kufunga nezvekudikanwa kwekubatanidza bandwidth, asiwo kudikanwa kwekureruka uye kungwara kushanda uye kugadzirisa, saka kuchinjika uye nyore network kuvakwa kwakava musimboti weDCI kuvaka.DCI application scenarios yakakamurwa kuita mhando mbiri: metro DCI uye kure-kure DCI, uye chinotariswa apa ndechekukurukura metro DCI musika.

DCI-BOX chizvarwa chitsva chevanoshandisa telecom mukuvaka kweiyo metropolitan network, vashandisi vanotarisira kukwanisa kuita optoelectronic decoupling, nyore kudzora, saka DCI-BOX inozivikanwa zvakare seyakavhurika decoupled optical network.

Yayo yakakosha hardware zvikamu zvinosanganisira: wavelength division transmission midziyo, optical modules, optical fibers uye zvimwe zvine hukama zvishandiso. Pakati pavo:

DCI wavelength division transmission equipment: inowanzo patsanurwa kuita magetsi layer products, optical layer products uye optical-electrical hybrid products, ndicho chigadzirwa chikuru che data center interconnection, chinosanganisira racks, mutsara side uye vatengi divi. Rutivi rwemutsetse unoreva chiratidzo chakatarisana nedivi rekutapurirana fiber, uye divi revatengi rinoreva chiratidzo chakatarisana nedivi rekuchinja.

Optical modules: kazhinji inosanganisira optical modules, coherent optical modules, nezvimwewo, avhareji yeanopfuura 40 optical modules inoda kuiswa mumudziyo wekutumira, chiyero chikuru che data center interconnections mu100Gbps, 400Gbps, uye ikozvino mukuedza. chikamu che800Gbps chiyero.

MUX/DEMUX: Nhepfenyuro yezviratidzo zvinotakura zvinotakura zvakasiyana-siyana zvakatakura ruzivo rwakasiyana-siyana zvinosanganiswa pamwe chete uye zvakabatanidzwa mune imwechete optical fiber yekutumira pakuguma kwekutumira kuburikidza neMUX (Multiplexer), uye zviratidzo zvemaziso zveavelengths akasiyana-siyana zvinoparadzaniswa. iyo yekupedzisira yekugamuchira kuburikidza neDemultiplexer (Demultiplexer).

AWG chip: DCI yakasanganiswa splitter MUX/DEMUX mainstream uchishandisa chirongwa cheAWG kuita.

Erbium Doped Fiber AmplifierEDFA: Chishandiso chinowedzera kusimba kwechiratidzo chisina kusimba chekupinza pasina kuchishandura kuita chiratidzo chemagetsi.

Wavelength Selection Shandura WSS: Iyo chaiyo kusarudzwa uye inochinjika kurongeka yewavelength yezviratidzo zvemaziso inowanikwa kuburikidza neiyo chaiyo optical chimiro uye chekudzora michina.

Optical Network Monitoring Module OCM uye OTDR: yeDCI network mashandiro emhando yekutarisa uye kugadzirisa. Optical Communication Channel Monitor OCPM, OCM, OPM, Optical Time Domain Reflectometer OTDR inoshandiswa kuyera fiber attenuation, kurasikirwa kwekubatanidza, fiber fault point nzvimbo uye kunzwisisa kurasikirwa kugoverwa kwehurefu hwefiber.

Optical Fiber Line Auto Shandura Dziviriro Equipment (OLP): Chinja otomatiki kune backup fiber kana iyo huru fiber ikatadza kupa akawanda dziviriro yesevhisi.

Optical Fiber Cable: Iyo yepakati yekufambisa data pakati penzvimbo dzedata.

Nekuenderera mberi kwekukura kwetraffic, huwandu hwe data inotakurwa neiyo imwe nzvimbo yedata, huwandu hwebhizinesi hushoma, DCI inogona kuvandudza zvirinani mwero wekushandiswa kwenzvimbo yedata, zvishoma nezvishoma yave nzira isingadzivisiki mukuvandudzwa kwenzvimbo dzedata, uye kudiwa kuchakura. Zvinoenderana newebhusaiti yepamutemo yeCiena, North America parizvino ndiyo musika mukuru weDCI, uye zvinofungidzirwa kuti dunhu reAsia-Pacific richapinda muhuwandu hwebudiriro mune ramangwana.
