Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Ukubuka konke kwezobuchwepheshe
Nakuba i-OSFP1600 isekela ama-switch chips azayo anemizila kagesi engu-200 Gb/s, kunentshisekelo eqinile yemakethe kumamojula angu-1.6 Tb/s optical asekelwe ku-100 Gb/s yomzila kagesi okhona kakade.
Lesi sidingo siholele ekuveleni kwesici sefomu le-OSFP-XD (eXtra Dense). Ngokwandisa inani lemizila kagesi ukusuka ku-8 kuya ku-16, i-OSFP-XD yenza umthamo we-1.6T (16×100 Gb/s) futhi ilungele umthamo we-3.2T (16×200 Gb/s) esikhathini esizayo.
Ngalawa makhono, i-OSFP-XD isekela izinhlobonhlobo zokucushwa kwesistimu. Kafushane, i-OSFP-XD iphinda kabili ukuminyana kwephaneli yangaphambili uma kuqhathaniswa ne-8-lane OSFP noma izici zefomu le-QSFP-DD.
1.6T OSFP-XD DR8 Optical Module
I-1.6T OSFP-XD DR8 optical module iphawula impumelelo enkulu ekuxhumaneni okubonakalayo okunesivinini esikhulu, isekela izinga ledatha elihlaba umxhwele elingafika ku-1.6 Tbps (ama-terabits ngomzuzwana).
Ngokusekelwe kusici sefomu se-OSFP-XD (Octal Small Form-factor Pluggable – eXtended Density), le mojula ihlanganisa ubuchwepheshe obuthuthukisiwe futhi yakhelwe inhloso ukuze ihlangabezane nezidingo zomkhawulokudonsa ezikhulayo zezikhungo zedatha zesimanje, i-cloud computing, kanye nemithwalo yemisebenzi ye-AI.
Isakhiwo sayo se-DR8 sisebenzisa iziteshi ezihambisanayo ezingu-8 futhi iletha ukusebenza okunamandla ngefayibha yemodi eyodwa, okuyenza ifaneleke kakhulu izinhlelo zokusebenza zokuxhumanisa okude.
Ukubaluleka Ezikhungweni Zedatha Yesimanje
Njengoba izikhungo zedatha zikala ukuze zibambe amavolumu amakhulu edatha aqhutshwa i-AI, ukufundwa komshini, nezinhlelo zokusebenza ze-5G, isidingo somkhawulokudonsa ophezulu nokubambezeleka okuphansi sesikhulile. Imojula ye-1.6T OSFP-XD DR8 ibhekana nalezi zidingo ngokuhlinzeka kabili komkhawulokudonsa wabanduleli bayo be-800G ngenkathi igcina ukuhambisana nengqalasizinda ekhona. Iqhaza layo ekunikeni amandla amanethiwekhi aphezulu okuminyana, asebenza kahle kakhulu ikubeka njengesisekelo sezakhiwo zesikhungo sedatha yesizukulwane esilandelayo.
Ukucaciswa Okubalulekile Kwezobuchwepheshe Nezinto Ezintsha
I-Ultra-High Bandwidth ene-PAM4 Modulation
I-1.6T OSFP-XD DR8 optical module ifinyelela umkhawulokudonsa ophelele we-1.6 Tbps ngokusebenzisa amashaneli angu-8 parallel, ngalinye lisebenza ngenani ledatha elifika ku-212.5 Gb/s. Lokhu kudluliswa kwesivinini esikhulu kwenziwa kwenzeke ngobuchwepheshe be-PAM4 (4-level Pulse Amplitude Modulation), obufaka amabhithi edatha angu-2 ngophawu ngalunye. Uma kuqhathaniswa nokuguquguquka okujwayelekile kwe-NRZ, i-PAM4 iphinda kabili ukusebenza kahle komkhawulokudonsa.
Ubuchwepheshe be-PAM4 abukhulisi nje kuphela amanani wedatha futhi buthuthukise ukusebenza kahle kwe-spectral kodwa futhi kunciphisa isidingo sezinsiza ze-fiber. Sekuyifomethi yemodulation evamile yokuxhumana okubonakalayo okunesivinini esikhulu.
Ngesikhathi esifanayo, imojula iqinisekisa ukudluliswa kwedatha okuthembekile ngokusebenzisa ukulawulwa kobuqotho besignali emazingeni aphezulu wedatha, ukuhlangabezana nezidingo zokuxhuma okuphezulu kanye ne-low-latency intra-data center.
I-EML Laser Esebenza Kakhulu ene-Silicon Photonics Integration
Ingqikithi yemojuli i-EML (I-Electro-Absorption Modulated Laser), ehlanganisa ukuzinza kwelaser ye-DFB namandla okushintsha amandla esivinini esikhulu se-EAM. Lo mklamo unikeza izinzuzo ezibalulekile ezifana nokusetshenziswa kwamandla okuphansi, umugqa ophezulu, nomsindo ophansi.
Ngaphezu kwalokho, ngokuhlanganisa i-EML nobuchwepheshe be-silicon photonics, imojula ifinyelela usayizi wephakheji omncane, izindleko eziphansi zokukhiqiza, kanye nokusebenza kahle kwamandla okuthuthukisiwe.
Le nhlanganisela ayisekeli nje kuphela isikhungo sedatha esifinyeleleka kafushane esixhumanisa amamitha angu-500, kodwa futhi sikala kunethiwekhi ye-metro (MAN) kanye nezinhlelo zokusebenza ze-data center interconnect (DCI) ebangeni elingamakhilomitha ayi-10 kuya kwangu-40.
I-OSFP-XD Form Factor kanye ne-Hot-plugable Design
I-OSFP-XD iyisici sefomu lesizukulwane esilandelayo esixhumeka esidizayinelwe ukuthunyelwa komthamo omkhulu kakhulu. Inikeza izici ezilandelayo:
Amandla okuxhuma okushisayo: Amamojula angafakwa noma ashintshwe ngaphandle kokuphazamisa ukusebenza kwesistimu, ukuthuthukisa ukusebenza kahle kokulungisa kanye nokuguquguquka.
Isakhiwo esihlangene esinokusebenza okushisayo okuthuthukisiwe: Uma kuqhathaniswa namamojula e-OSFP endabuko, i-OSFP-XD ihlanganisa ukuminyana okuphezulu kwesixhumi nomklamo othuthukisiwe wokugeleza komoya, okuvumela ukusebenza okuzinzile kumazinga wamandla phakathi kuka-20 no-30W.
Ukucushwa kwembobo ye-High-density: Ngenkathi igcina usayizi womzimba ofanayo njenge-OSFP, i-OSFP-XD isekela izakhiwo eziminyanisa kakhulu—njengamachweba we-OSFP angu-64 ku-chassis engu-1U—ivumela amandla okushintsha afinyelele ku-51.2 Tbps.
Ukucushwa Okuguquguqukayo Nokuhambisana Okuqinile
Imojula yakhelwe ngokuhambisana okubuyela emuva kanye nokulinganisa kwesistimu engqondweni. Isekela ukusebenzisana okungenamthungo namamojula akhona we-800G OSFP, okwenza kube lula ukuthuthukiswa kwesistimu. Ikhono layo lokuhlala ndawonye futhi linqwabelene namanye amamojula e-OSFP noma e-OSFP-XD ebhodini elifanayo anika amandla ama-topology enethiwekhi nezinhlanganisela zokumisa.
Ukwengeza, i-architecture exhunywayo igcina izinzuzo ezibalulekile zamamojula wendabuko we-optical-ukulungiswa kalula, ukulungiswa, nokuthuthukiswa-ukuhambisana kahle nezinqubo zokuthenga zamanje endaweni yenkampani yenethiwekhi nesikhungo sedatha.
Ukusebenza Amandla kanye Namathuba Esikhathi esizayo
Ukuhlangabezana nezidingo ezikhulayo zomkhawulokudonsa, imojula isebenzisa amasu okuphatha amandla athuthukile. Ukusetshenziswa kwamandla okujwayelekile kugcinwa ngaphakathi kwebanga elingu-20–30W. Idizayini esebenzayo yokushisa kanye nesiqondiso sokugeleza komoya kusiza ukubhekana nezinselele zokunqanyulwa kokushisa ekusetshenzisweni kokuminyana okuphezulu. Uma ubheka phambili, indlela yokuziphendukela kwemvelo icacile—intuthuko kubuchwepheshe be-DSP ebheke ezinqubweni ze-3nm ne-2nm kulindeleke ukuthi yehlise ukusetshenziswa kwamandla ku-5–6 pJ/bit, kuqhubeke kuthuthukise ukusebenza kahle kohlelo lonke.
Amazinga Omkhakha Nokuhambisana
I-1.6T OSFP-XD DR8 optical module ithobelana ngokuqinile nemininingwane yezobuchwepheshe ye-1600G Ethernet kanye nezinga le-OSFP-XD Multi-Source Agreement (MSA).
I-1600G Ethernet: Njengesixhumi esibonakalayo se-Ethernet yesizukulwane esilandelayo, ichaza isilinganiso esihlanganisiwe se-1.6 Tb / s futhi isekela ukuthuthukiswa kwe-ultra-high-speed yamanethiwekhi omgogodla wesikhungo sedatha.
I-OSFP-XD MSA: Izinga lokupakisha elithuthukiswe ngokuhlanganyela abakhiqizi bemboni abaholayo ukuze kuqinisekiswe ukuhambisana kwemishini, ugesi, nokubona phakathi kwamamojula avela kubahlinzeki abahlukahlukene, ukwehlisa ukuthengwa kwempahla kanye nezingozi zokuphakela kubasebenzisi.
I-1.6T OSFP-XD DR8 optical module ihlanganisa impumelelo eyinhloko njengokumodulation kwe-PAM4, amalaser e-EML esivinini esikhulu, ukuhlanganiswa kwe-silicon photonic, kanye ne-OSFP-XD ephezulu yokupakisha. Ifinyelela isivinini esikhulu, amandla aphansi, kanye namakhono okudlulisa idatha asondelene kakhulu. Iphinde inikeze ukuhambisana kwesistimu okuhle kakhulu kanye nokulinganisa okuzayo. Lezi zici zikwenza kube yisixazululo esibalulekile sokuxhumanisa i-AI yesizukulwane esilandelayo sezikhungo zedatha ye-hyperscale.
