I-QQSFP -DD 800G iza ngokumelene nomoya
Amandla esikhungo sedatha anqunywa amaseva, amaswishi, nezici zokuxhuma ezibhalansayo futhi ezisunduzana ekukhuleni okusheshayo, okunezindleko eziphansi.Ukushintsha ubuchwepheshe kube yiwona mandla amakhulu okushayela iminyaka eminingi.Njengoba i-OFC2021 izophela muva nje, abakhiqizi bezokuxhumana abajwayelekile abafana ne-Intel, Finisar, Xechuang, Opticexpress kanye ne-New Yisheng bonke babonise amamojula angama-800G ochungechunge.Ngesikhathi esifanayo, izinkampani zaphesheya kwezilwandle ze-optical chip zibonise imikhiqizo ye-chip ephezulu ye-800G, futhi uhlelo lwendabuko lungase lube nendawo esikhathini se-800G.Sicabanga ukuthi umzila we-800G optical module technology ucace kakhulu, i-800GDR8 kanye ne-2*FR4 inamandla ajwayelekile kakhulu;Njengoba i-OFC2021 imojula yokubona ehamba phambili kanye nezinkampani ze-optical chip zethule imikhiqizo emisha ngokulandelana, indawo yesikhathi nomzila wobuchwepheshe ojwayelekile wokuthuthukiswa kwe-800G uchaziwe.Izinga lemboni yedatha yedatha ye-optical module iyaqhubeka nokuphindaphinda, futhi imfanelo yokukhula yesikhathi eside inqunyiwe.Sikholelwa ukuthi esikhathini sedijithali nobuhlakani, ukuqhuma okuqhubekayo kwethrafikhi yesikhungo sedatha kulethe isidingo sokuphindaphinda okuqhubekayo kwamamojula optical.Umzila wobuchwepheshe ocacile we-800G ubonisa ukuthi i-400G izoba enkulu.
Lapho izinga lesiginali le-25Gbps lithuthukele kuzinga lesignali lamanje le-56Gbps, ngenxa yokwethulwa kwesistimu yesignali ye-PAM4 (Pulse Amplitude Modulation) (iqembu le-IEEE 802.3BS), Iphuzu eliyisisekelo lemvamisa yesiginali ehanjiswa kusixhumanisi se-Serdes Ethernet liya phezulu kuphela. ukusuka ku-12.89ghz ukuya ku-13.28ghz, futhi iphoyinti lemvamisa yesignali eliyisisekelo alishintshi kakhulu.Amasistimu angasekela ukudluliswa okuhle kwamasiginali we-25Gbps angathuthukiswa abe ku-56Gbps esilinganisweni sokwenziwa ngcono kancane.Ukuthuthuka kusuka ku-56Gbps izinga lesignali kuya ku-112Gbps izinga lesignali akulula kangako.Isistimu yesignali ye-PAM4 eyethulwe lapho izinga lezinga le-56Gbps lithuthukiswa cishe lizophinda lisetshenziswe kumazinga we-112Gbps.Lokhu kushintsha iphoyinti eliyisisekelo lemvamisa yesignali ye-112Gbps Ethernet ibe ngu-26.56ghz, okuyisilinganiso esiphindwe kabili kunesika-56Gbps.Ekukhiqizeni izinga le-112Gbps, izidingo zobuchwepheshe bekhebula zizobhekana nokuhlolwa okudinga kakhulu.Njengamanje, ikhebula lejubane eliphezulu elingu-400Gbps lixhunywe kumkhiqizo.Imikhiqizo esheshe yavuthwa ikakhulukazi amabhrendi angaphandle, njenge-TE, LEONI, MOLEX, Amphenol, njll. Imikhiqizo yasekhaya nayo isiqalile ukudlula eminyakeni yakamuva.Kusukela enqubweni yokukhiqiza, izinto zokusebenza nezinto zokwakha, senze izinto ezintsha eziningi.Njengamanje, kukhona amabhizinisi asekhaya akhiqiza intambo yethusi engu-800G, kodwa asikaqoqi okuningi.I-Shenzhen Hongteda, i-Dongguan Zhongyou Electronics, i-Dongguan Jinxinuo, i-Shenzhen Simic Communication, njll., kodwa ubunzima bobuchwepheshe obukhona ikakhulukazi buyingxenye yocingo olungenalutho.Njengamanje, kunzima kakhulu ukuxazulula imingcele yokusebenza kagesi eyimvamisa ephezulu kanye nezidingo zokuthamba kwezintambo zekhebula ngasikhathi sinye.Intambo yethusi ye-DAC izobhekana nesikhathi sokuthuthuka okusheshayo.Kunedlanzana labakhiqizi bezintambo bendawo.
Imakethe ishintsha ngokushesha, futhi izovela ngokushesha nakakhulu esikhathini esizayo.Izindaba ezinhle ukuthi inqubekelaphambili ebalulekile futhi ethembisayo yenziwe, kusukela emigwaqweni yamazinga kuya embonini, ukuze izikhungo zedatha zikwazi ukuya ku-400GB naku-800GB.Kodwa ukususa imigoqo yezobuchwepheshe kuyingxenye yenselele kuphela.Enye ingxenye yisikhathi.Uma ukwahlulela okungalungile kwenzeka, izindleko zizoba phezulu.Okujwayelekile kwesikhungo sedatha sasekhaya esikhona yi-100G.Phakathi kwezikhungo zedatha ze-100G ezisetshenzisiwe, i-25% yethusi, i-50% i-fiber yemodi eminingi, kanti i-25% i-fiber eyodwa-module.Lezi zinombolo zesikhashana azinembile, kodwa isidingo esikhulayo somkhawulokudonsa, umthamo, nokubambezeleka okuphansi kushayela ukuthuthela esivinini senethiwekhi esisheshayo.Ngakho-ke minyaka yonke, ukuguquguquka nokusebenza kwezikhungo zedatha yamafu amakhulu kuwukuhlola.Njengamanje, i-100GB igcwele imakethe, kanti i-400GB kulindeleke ngonyaka ozayo.Naphezu kwalokhu, ukugeleza kwedatha kusaqhubeka nokukhula, ukucindezela kwezikhungo zedatha kuzoqhubeka nokukhula, kulandela i-400G, i-QSFP-DD 800G ifikile.
