DCI Typical Architecture and Industry Chain

Posachedwa, motsogozedwa ndi chitukuko chaukadaulo wa AI ku North America, kufunikira kwa kulumikizana pakati pa ma node a masamu a masamu kwakula kwambiri, ndipo ukadaulo wolumikizana wa DCI ndi zinthu zina zofananira zakopa chidwi pamsika, makamaka pamsika wamalikulu.

DCI (Data Center Interconnect, kapena DCI mwachidule), kapena Data Center Interconnect, ndiyo kulumikiza malo osiyanasiyana a deta kuti akwaniritse kugawidwa kwazinthu, kukonza ndi kusunga deta. Pomanga njira DCI, osati muyenera kuganizira kufunika kwa kugwirizana bandiwifi, komanso kufunika chosavuta ndi wanzeru ntchito ndi kukonza, kotero kusintha ndi yabwino maukonde yomanga wakhala pachimake pa DCI Construction.DCI zochitika ntchito anawagawa mu mitundu iwiri: metro DCI ndi DCI wamtunda wautali, ndipo cholinga chake ndikukambirana msika wa metro DCI.

DCI-BOX ndi m'badwo watsopano wa opanga ma telecom pamapangidwe a network ya metropolitan, ogwira ntchito amayembekeza kuti athe kupanga ma optoelectronic decoupling, osavuta kuwongolera, kotero DCI-BOX imadziwikanso kuti open decoupled Optical network.

Zigawo zake zazikuluzikulu za hardware zikuphatikizapo: zida zopatsirana za wavelength division, ma modules optical, optical fibers ndi zipangizo zina zogwirizana. Mwa iwo:

DCI wavelength magawano kufala zida: kawirikawiri anawagawa mankhwala wosanjikiza magetsi, kuwala wosanjikiza mankhwala ndi kuwala-magetsi mankhwala wosakanizidwa, ndiye chinthu chachikulu cha data pakati interconnection, wopangidwa moyikamo, mbali mzere ndi mbali kasitomala. Mbali ya mzere imatanthawuza chizindikiro chomwe chimayang'ana mbali yotumizira ulusi, ndipo mbali yamakasitomala imatanthawuza chizindikiro chomwe chikuyang'ana mbali yosinthira.

Ma module a Optical: nthawi zambiri amaphatikizapo ma modules optical, optical modules, etc., pafupifupi oposa 40 optical modules ayenera kuikidwa mu chipangizo chotumizira, chiwerengero chachikulu cha data center interconnections mu 100Gbps, 400Gbps, ndipo tsopano mu mayesero. gawo la 800Gbps mlingo.

MUX/DEMUX: Mndandanda wa ma siginecha onyamula amitundu yosiyanasiyana omwe amanyamula zidziwitso zosiyanasiyana amaphatikizidwa pamodzi ndikuphatikizidwa mu ulusi womwewo wa kuwala kuti utumizidwe pamapeto otumizira kudzera mu MUX (Multiplexer), ndipo ma siginecha owoneka a mafunde osiyanasiyana amasiyanitsidwa. mapeto olandira kudzera mu Demultiplexer (Demultiplexer).

Chip cha AWG: DCI yophatikiza ma splitter MUX/DEMUX odziwika bwino pogwiritsa ntchito pulogalamu ya AWG kuti akwaniritse.

Erbium Doped Fiber AmplifierEDFA: Chipangizo chomwe chimakulitsa kulimba kwa siginecha yamphamvu yolowera popanda kuyisintha kukhala chizindikiro chamagetsi.

Wavelength Selection Switch WSS: Kusankhidwa kolondola komanso kusinthasintha kwa kutalika kwa ma siginecha owoneka kumazindikirika kudzera munjira yolondola komanso yowongolera.

Optical Network Monitoring Module OCM ndi OTDR: ya DCI network yowunikira komanso kukonza magwiridwe antchito. Optical Communication Channel Monitor OCPM, OCM, OPM, Optical Time Domain Reflectometer OTDR amagwiritsidwa ntchito poyesa kutayika kwa fiber, kutayika kwa cholumikizira, malo olakwika a fiber ndikumvetsetsa kugawa kwautali wa fiber.

Optical Fiber Line Auto Switch Protection Equipment (OLP): Sinthani zokha kukhala zosunga zobwezeretsera ulusi waukulu ukalephera kupereka chitetezo chambiri pautumiki.

Chingwe cha Optical Fiber: Sing'anga yotumizira ma data pakati pa ma data center.

Ndi kukula kosalekeza kwa magalimoto, kuchuluka kwa deta yomwe imatengedwa ndi malo amodzi a deta, kuchuluka kwa bizinesi kumakhala kochepa, DCI ikhoza kupititsa patsogolo kuchuluka kwa magwiritsidwe ntchito a data center, pang'onopang'ono yakhala njira yosapeŵeka pakukula kwa malo opangira deta, ndipo kufunika kudzakula. Malinga ndi tsamba lovomerezeka la Ciena, North America pakadali pano ndiye msika waukulu wa DCI, ndipo zikuloseredwa kuti dera la Asia-Pacific lidzalowa pachitukuko chachikulu mtsogolomo.
