"Ukuncintisana kakhulu" kuyindlela engcono kakhulu yokuhlukanisa imakethe yemishini ye-Optical Transport DWDM. Nakuba kuyimakethe enkulu, enesisindo esingamaRandi ayizigidi eziyizinkulungwane ezingu-15, kunabakhiqizi bezinhlelo abangaba ngu-20 abahlanganyela ngenkuthalo ekuthengiseni imishini ye-DWDM futhi bancintisana ngamandla ukuthola isabelo semakethe. Lokho kusho ukuthi, amaphesenti angu-90 emakethe aphethwe ngabathengisi abayisikhombisa kuphela, okushiya amaphesenti ayi-10 kubathengisi abasele, futhi ngisho naphakathi kwabayisikhombisa abaphezulu, i-delta yesabelo semakethe inkulu—amaphuzu angu-25 amaphesenti phakathi komthengisi omkhulu nomncane kunabo bonke.
Isikali senkampani kanye nokutshalwa kwezimali kuyisici esibalulekile sokuhlukanisa imakethe, lapho phakathi kwabathengisi abaphezulu, ngaphandle kwe-FiberHome, bonke betshale imali ekuhlanganisweni okuqondile ezingxenyeni eziseceleni komugqa njenge-coherent DSP kanye ne-optical front end. Akubonakali kunendaba ukuthi i-optical front end isekelwe ku-Silicon Photonics (SiPh) noma ku-Indium Phosphide (InP) yize ochwepheshe bemboni beqhubeka nokuxoxisana ngobuchwepheshe obubili. Isici esinqumayo ukuthi inkampani ithuthukise ubuchwepheshe bangaphakathi obuhlukanisa imikhiqizo kwabanye, bunciphise izindleko zomkhiqizo wayo, futhi bunike inkampani isikhathi esingcono sokumaketha. Ngaphezu kwalokho, njengoba kuthatha isilinganiso esikhulu kanye nezinsizakusebenza (imali, abantu, kanye nempahla yobuhlakani) ukuthuthukisa lezi zingxenye, ukuhlanganiswa okuqondile kudala isithiyo kubafaki abasha (ngisho nabadala).
Ukufakwa Komkhiqizo Esikhundleni Kuyatholakala
Njengezimboni eziningi, amandla angaphandle embonini ye-Optical Transport ukushintsha umkhiqizo. Nakuba ukushintsha umkhiqizo kwakungeyona ingozi yangempela emashumini eminyaka adlule, ngenxa yezinzuzo ezikhona ekusebenzeni kanye nezindleko zobuchwepheshe be-DWDM kanye nemikhawulo yezinga lesistimu yokufaka ubuchwepheshe be-DWDM epulatifomu eseduze, isimo siqala ukuguquka kancane ngama-optics amancane e-form factor 400ZR pluggable. Ngenxa yalezi zinhlobo ezintsha ze-pluggable ku-QSFP-DD form factor engadlulisela ubude bama-wavelength angu-400 Gbps kuze kufike kumakhilomitha angu-120, silindele intshisekelo ekhulayo ku-IP-over-DWDM (IPoDWDM), okuwukwakhiwa kwesistimu okuhlanganisa ama-optics e-DWDM ku-Ethernet Switch noma ku-Router. Lokhu, ngaphandle kokusho, kuzokhulisa izinga lokuncintisana endaweni yemishini ye-DWDM njengoba amakhasimende enquma phakathi kokusebenzisa uhlelo lwendabuko lwe-DWDM oluvela kubathengisi bethu abangu-20 be-DWDM noma uhlelo lwe-IPoDWDM oluvela kwabanye abathengisi abashintshayo. (Abathengisi abaphezulu be-Ethernet Switch kanye ne-Router bafaka i-Arista, i-Cisco, i-Juniper, ne-Nokia).
Kodwa-ke, i-400ZR izophinde izuzise abathengisi be-optical DWDM. Esinye isizathu ukuthi akubona bonke abaqhubi abazofuna ukushintsha inethiwekhi yabo ibe yi-IPoDWDM futhi bazokhetha ukusebenzisa ama-optics axhumekayo angu-400ZR ohlelweni lwe-DWDM, bagcine ukwakheka kwenethiwekhi kungashintshi ngenkathi bezuza ezindlekweni eziphansi zama-optics angu-400ZR. Kodwa esinye isizathu ukuthi i-400ZR ubuchwepheshe obuhambisanayo ngakho-ke izinkampani ezitshale imali kulobu buchwepheshe eminyakeni eyishumi edlule zisesimweni esihle sokubhekana naleli thuba elisha. Ngakho-ke, abakhiqizi be-optics exhumekayo engu-400ZR bakhiwa kakhulu yizinkampani ezinomlando omude ekuthuthukisweni kwezinhlelo ze-DWDM ezihambisanayo, njengeCiena, iCisco, neNokia. IHuawei yayihlose ukuthuthukisa ne-400ZR, kodwa asiqiniseki ukuthi imikhawulo yase-US enkampanini izolibazisa yini lo msebenzi.
Amakhasimende Akhetha Abaphakeli Bendawo Uma Betholakala
Ngandlela thile lokhu akukudala futhi akukusha, kodwa kubalulekile ukugcizelela ukuthi ngokuvamile amakhasimende akhetha ukuthenga imishini kumhlinzeki wendawo. Kuleli shadi, imakethe yemishini ye-DWDM yomhlaba wonke ihlukaniswe ngezifunda ezinkulu kanye nabathengisi abahlinzeka esifundeni esithile. Ubukhulu bebhokisi bubonisa isabelo sabathengisi kuleso sifunda, kanti amabhokisi anombala oluhlaza okwesibhakabhaka ngabathengisi ababhekwa njengabomakhelwane kuleso sifunda. Akumangazi ukuthi ezifundeni ezimbili—eNyakatho Melika naseShayina—lapho kunenani elikhulu labathengisi basekhaya, inani elikhulu lokuthengiswa kwe-DWDM liya kulezi zinkampani zasekhaya. Ngenxa yokuxubana okukhulu kwezinkampani “kwabanye,” angizange ngifake umthunzi kulawo mabhokisi, kodwa kokubili eNyakatho Melika naseShayina iningi “labanye” yizinkampani zasekhaya.
Okungaba nesithakazelo ngamabhokisi angenawo umthunzi. Isizathu ukuthi ngemuva kokuba i-US ibeke imingcele ku-ZTE ngo-2018 kanye ne-Huawei muva nje, abahlinzeki bezinsizakalo ezifundeni ezinenani elikhulu lamabhokisi angenawo umthunzi (abathengisi abangebona abasekhaya) bakhathazeka kakhulu ngokuhlinzekwa kwemishini. Ngenxa yalokho, abahlinzeki bezinsizakalo bafuna ukunciphisa ubungozi ngokunciphisa ukuncika kunoma yimuphi umhlinzeki kanye nokwandisa ukucatshangelwa kwabahlinzeki bendawo. Ngezindlela eziningi, lokhu kuzoba kuhle ezinkampanini ezincane ezisezifundeni zasendaweni njengeTejas eNdiya, iPadtec eCALA, kanye nePacketLight e-EMEA. Kodwa-ke, ngenxa yokunciphisa ubungozi, abahlinzeki bezinsizakalo abakhulu cishe bazoqhubeka nokuthenga imishini eminingi kubakhiqizi abakhulu be-DWDM abanobukhulu nobuchwepheshe bokusekela imizamo yabo yesikhathi esizayo.
Isimo Esiguquguqukayo Semboni
Mhlawumbe indlela engcono kakhulu yokuchaza isimo semboni yemishini ye-optical WDM kulo nyaka "ingukuguquguquka." Ngisho lokhu ngoba ngokungafani nesikhathi esidlule lapho amandla emboni ayefana unyaka nonyaka, kwavela amandla amasha embonini ye-optical kulo nyaka angase ayishintshe ngokuguquguqukayo. Ngokuqondile, amandla amasha engikhuluma ngawo ukusebenza okuphezulu kokushintshaniswa komkhiqizo ne-IPoDWDM enikwe amandla yi-400ZR ku-plug ye-QSFP-DD kanye noshintsho ekuziphatheni kwamakhasimende okudalwe yizenzo zikahulumeni wase-US kubakhiqizi baseShayina ezingashintsha isimo sabathengisi ezindaweni ezithile ngokuhamba kwesikhathi.
