QQSFP -DD 800G inouya kuzorwa nemhepo
Data center kugona kunotemerwa nemaseva, switch, uye yekubatanidza zvinhu zvinoenzanisa uye kusundirana kune nekukurumidza, kuderera-mutengo wekukura.Kuchinja tekinoroji kwave kuri kufambisa kukuru kwemakore mazhinji.Sezvo OFC2021 inosvika kumagumo nguva pfupi yadarika, vagadziri vemagetsi ekutaurirana vakadai seIntel, Finisar, Xechuang, Opticexpress neNew Yisheng vese vakaratidza 800G series optical modules.Panguva imwecheteyo, makambani ekumhiri kwemakungwa optical chip airatidza zvigadzirwa zvepamusoro zve800G, uye chirongwa chetsika chinogona kunge chichine nzvimbo munguva ye800G.Isu tinofunga kuti 800G optical module tekinoroji nzira inowedzera uye yakajeka, 800GDR8 uye 2 * FR4 vane mikana yakawanda yakawanda;Sezvo OFC2021 mainstream optical module uye optical chip makambani akatangisa zvigadzirwa zvitsva chimwe mushure mechimwe, nguva node uye mainstream tekinoroji nzira ye800G yekusimudzira yakatsanangurwa.Chiyero che data center optical module indasitiri inoenderera mberi, uye hunhu hwekukura kwenguva refu hwakatemerwa.Isu tinotenda kuti munguva yedhijitari uye hungwaru, kuenderera kunoramba kuchiputika kwe data center traffic kwaunza kudiwa kwekuenderera mberi iteration ye optical modules.Iyo yakajeka tekinoroji nzira ye800G inoratidza kuti 400G ichave yakakura-mwero.
Kana iyo 25Gbps chiyero chechiratidzo ichikwidziridzwa kusvika kune yazvino 56Gbps chiratidzo cheyero, nekuda kwekuiswa kwePAM4 (Pulse Amplitude Modulation) chiratidzo system (IEEE 802.3BS boka), Iyo yakakosha frequency point yechiratidzo chinopfuudzwa paSerdes Ethernet link inokwira kumusoro. kubva 12.89ghz kusvika 13.28ghz, uye chiratidzo chakakosha frequency point haina kuchinja zvakanyanya.Masisitimu anogona kutsigira kutapurirana kwakanaka kwe25Gbps masaini anogona kukwidziridzwa kusvika ku56Gbps masaini mareti ane zvishoma optimization.Kuvandudza kubva ku56Gbps chiratidzo chechiratidzo kusvika ku112Gbps chiratidzo chechiratidzo hakusi nyore.Iyo PAM4 chiratidzo system yakaunzwa apo iyo 56Gbps chiyero cheyero yakagadziridzwa ichanyanya kushandiswa zvakare pa112Gbps mitengo.Izvi zvinoshandura yakakosha frequency point ye112Gbps Ethernet chiratidzo kuenda ku26.56ghz, inova yakapetwa kaviri ye56Gbps chiratidzo chechiratidzo.Muchizvarwa che112Gbps chiyero, iyo tambo tekinoroji inodiwa ichasangana neinoda bvunzo.Parizvino, 400Gbps high-speed cable yakabatanidzwa kune chigadzirwa.Mabhureki ekutanga akanyanya kunyanya ekunze, akadai seTE, LEONI, MOLEX, Amphenol, nezvimwewo. Zvigadzirwa zvemumba zvakatangawo kudarika mumakore achangopfuura.Kubva pakugadzira, midziyo uye zvinhu, takaita zvakawanda zvitsva.Parizvino, kune mabhizinesi epamba anogadzira 800G copper cable, asi isu hatina kuunganidza zvakawanda.Shenzhen Hongteda, Dongguan Zhongyou Electronics, Dongguan Jinxinuo, Shenzhen Simic Kukurukurirana, nezvimwewo, asi kuoma kwehunyanzvi huripo kuri kunyanya muchikamu chisina waya.Parizvino, zvakaoma kugadzirisa iyo yakakwirira frequency magetsi ekuita paramita uye zvinyoro zvinodiwa zvetambo wiring panguva imwe chete.DAC copper cable ichasangana nenguva yekukurumidza kusimudzira.Kune vashoma chete vemunharaunda vanogadzira waya.
Musika uri kuchinja nekukurumidza, uye uchashanduka nekukurumidza mune ramangwana.Nhau dzakanaka ndedzekuti kufambira mberi kwakakosha uye kunovimbisa kwaitwa, kubva kumitumbi yezviyero kuenda kuindasitiri, kugonesa nzvimbo dzedata kuenda ku400GB uye 800GB.Asi kubvisa zvipingamupinyi zvetekinoroji ihafu yedambudziko.Imwe hafu inguva.Kana kutadza kutonga kwaitika, mari yacho inokwira.Iyo huru yenzvimbo iripo yedata data centre ndeye 100G.Pakati pezvakaiswa 100G data centers, 25% imhangura, 50% yakawanda-mode fiber, uye 25% ndeye single-module fiber.Idzi nhamba dzenguva hadzina chaidzo, asi kukura kuri kudiwa kwebandwidth, huwandu, uye yakaderera latency iri kutyaira kutama kune nekukurumidza network kumhanya.Saka gore rega rega, kuchinjika uye kugona kwemahombe-akura data nzvimbo bvunzo.Parizvino, 100GB iri kufashama pamusika, ne400GB inotarisirwa gore rinouya.Pasinei neizvi, kuyerera kwe data kuchiri kuramba kuchiwedzera, kudzvinyirirwa kwezvivako zve data kucharamba kuchiwedzera, kutevera 400G, QSFP-DD 800G yasvika.
