"Ukuncintisana kakhulu" kuyindlela engcono kakhulu yokuveza imakethe yemishini ye-Optical Transport DWDM.Nakuba iyimakethe enkulu, enesisindo esingamaRandi ayizigidi eziyizinkulungwane ezingu-15, kukhona abakhiqizi bezinhlelo abangaba ngu-20 ababamba iqhaza elibonakalayo ekuthengiseni imishini ye-DWDM futhi balwela ukwabelana ngemakethe.Sekushiwo lokho, amaphesenti angu-90 emakethe aphethwe abathengisi abayisikhombisa kuphela, okushiya amaphesenti angu-10 kubathengisi abasele, futhi ngisho naphakathi kwabayisikhombisa abaphezulu, i-delta yesabelo semakethe inkulu—amaphesenti angu-25 phakathi komthengisi omkhulu kunabo bonke.
Isilinganiso senkampani kanye nokutshalwa kwezimali kungumhlukanisi oyinhloko obonakala ehlukanisa imakethe, lapho phakathi kwabathengisi abaphezulu, ngaphandle kwe-FiberHome, bonke betshale imali ekuhlanganisweni okuqondile ezingxenyeni eziseceleni komugqa njenge-DSP ehambisanayo kanye nesiphetho sangaphambili esibonakalayo.Akubonakali kungenandaba ukuthi indawo engaphambili ye-optical isekelwe ku-Silicon Photonics (SiPh) noma i-Indium Phosphide (InP) nakuba ongoti bezimboni beqhubeka nokuphikisana ngalobu buchwepheshe obubili.Isici esinqumayo ukuthi inkampani ithuthukise ubuchwepheshe bangaphakathi endlini obuhlukanisa imikhiqizo kwabanye, yehlise izindleko zomkhiqizo wayo, futhi inikeze inkampani isikhathi esingcono sokumaketha.Ngaphezu kwalokho, njengoba kuthatha isilinganiso esikhulu nezinsiza (imali, abantu, kanye nempahla yengqondo) ukuthuthukisa lezi zingxenye, ukuhlanganiswa okuqondile kudala umgoqo kwabangenayo abasha (ngisho nabadala).
Ukushintshwa Komkhiqizo Kuyatholakala
Njengezimboni eziningi, amandla angaphandle embonini ye-Optical Transport ukufaka esikhundleni somkhiqizo.Nakuba ukushintshwa komkhiqizo bekungelona usongo lwangempela emashumini eminyaka adlule, ngenxa yezinzuzo ezikhona ekusebenzeni kanye nezindleko zobuchwepheshe be-DWDM kanye nezingqinamba zezinga lesistimu ekufakeni ubuchwepheshe be-DWDM endaweni eseduze, igagasi seliqala ukuphenduka kancane ifomu elincane le-400ZR optics elixhumekayo.Njengomphumela walawa ma-optics amasha axhumeke ku-QSFP-DD form factor engadlulisa amaza wamaza angu-400 Gbps kufika kumakhilomitha angu-120, silindele isithakazelo esikhulayo ku-IP-over-DWDM (IPoDWDM), okuwuhlelo lwezakhiwo oluhlanganisa i-DWDM. optics ku-Ethernet Switch noma Router.Lokhu, ngaphandle kokusho, kuzokwandisa izinga lokuncintisana endaweni yemishini ye-DWDM njengoba amakhasimende enquma phakathi kokusebenzisa uhlelo lwe-DWDM lwendabuko oluvela kubathengisi bethu be-DWDM abangama-20 noma uhlelo lwe-IPoDWDM oluvela kwabanye abathengisi abashintshayo.(Abathengisi abaphezulu be-Ethernet Switch kanye ne-Router bahlanganisa i-Arista, i-Cisco, iJuniper, ne-Nokia).
Kodwa-ke, i-400ZR izophinde izuze abathengisi be-DWDM ababonakalayo.Esinye isizathu siwukuthi akubona bonke opharetha abazofuna ukushintsha inethiwekhi yabo ku-IPoDWDM futhi bazokhetha ukusebenzisa i-400ZR pluggable optics ohlelweni lwe-DWDM, ukugcina ukwakheka kwenethiwekhi kungashintshile ngandlela-thile ngenkathi bezuza ezindlekweni eziphansi ze-400ZR optics.Kodwa esinye isizathu ukuthi i-400ZR iwubuchwepheshe obuhlangene ngakho-ke izinkampani ezitshale imali kulobu buchwepheshe eminyakeni eyishumi edlule zisesimweni esihle sokubhekana naleli thuba elisha.Ngakho-ke, abakhiqizi be-400ZR pluggable optics iningi labo lakhiwe izinkampani ezinomlando omude ekuthuthukisweni kwezinhlelo ezihambisanayo ze-DWDM, njenge-Ciena, Cisco, ne-Nokia.UHuawei uhlose ukuthuthukisa i-400ZR futhi, kodwa asinaso isiqiniseko sokuthi imikhawulo yase-US enkampanini izobambezela yini lo mzamo.
Amakhasimende Ancamela Abahlinzeki Bendawo Uma Ikhona
Ngandlela thize lokhu akukudala futhi akukusha, kodwa kubalulekile ukugcizelela ukuthi ngokuvamile amakhasimende akhetha ukuthenga izinto zokusebenza kumnikezeli wendawo.Kuleli shadi, imakethe yemishini ye-DWDM yomhlaba wonke isikwe izifunda ezinkulu kanye nabathengisi abahlinzeka ngesifunda esithile.Ubukhulu bebhokisi bubonisa isabelo somthengisi kuleso sifunda, futhi amabhokisi anomthunzi oluhlaza abathengisi ababhekwa njengasekhaya kuleso sifunda.Akumangazi ukuthi ezifundeni ezimbili—eNyakatho Melika naseChina—lapho kunenani elikhulu labathengisi basekhaya, inani elikhulu lokuthengiswa kwe-DWDM liya kulezi zinkampani zasekhaya.Ngenxa yokuxubana okuphezulu kwezinkampani "kwabanye," angizange ngifake umthunzi kulawo mabhokisi, kodwa eNyakatho Melika naseChina iningi "labanye" yizinkampani zasekhaya futhi.
Okungase kuthakazelise amabhokisi angenawo umthunzi.Isizathu siwukuthi ngemva kokuba i-US ibeke imingcele ku-ZTE ngo-2018 futhi muva nje iHuawei, abahlinzeki bezinsizakalo ezifundeni ezinenani elikhulu lamabhokisi angenawo umthunzi (abathengisi abangewona asekhaya) bakhathazeka kakhulu ngokuhlinzekwa kwemishini.Ngenxa yalokho, abahlinzeki besevisi babheke ukususa ubungozi ngokunciphisa ukuncika kunoma yimuphi umphakeli oyedwa kanye nokukhulisa ukucabangela kwabahlinzeki bendawo.Ngezindlela eziningi, lokhu kuzoba kuhle ezinkampanini ezincane ezizinze ezifundeni zasendaweni njenge-Tejas e-India, i-Padtec e-CALA, ne-PacketLight e-EMEA.Kodwa-ke, emgudwini wokunciphisa ubungozi, abahlinzeki besevisi abakhulu kakhulu cishe bazoqhubeka nokuthenga amathuluzi amaningi kubakhiqizi abakhulu be-DWDM abanesilinganiso nobuchwepheshe bokusekela imizamo yabo yesikhathi esizayo.
Isimo Semboni Esinamandla
Mhlawumbe indlela engcono kakhulu yokuchaza isimo semboni yemishini ye-Optical WDM kulo nyaka “inamandla.”Lokhu ngikusho ngoba ngokungafani nakudala lapho amandla ezimboni ayefana unyaka nonyaka, kuqhamuke amandla amasha embonini ye-optical kulo nyaka okungenzeka ukuthi ayibumbe kabusha.Ikakhulukazi, amandla amasha engikhuluma ngawo wukusebenza okuphezulu kokushintshwa komkhiqizo nge-IPoDWDM enikwe amandla i-400ZR kupulaki ye-QSFP-DD kanye noshintsho ekuziphatheni kwamakhasimende okudalwe izenzo zikahulumeni wase-US kubakhiqizi baseShayina ezingashintsha isimo somthengisi ezindaweni ezithile. ngokuhamba kwesikhathi.
