Naqshaduhu waxay u hoggaansamaan 100GbASE-LR4 ee IEEE 802.3-2012 Farqada 88 heerka IEEE 802.3bm CAUI-4 chip ilaa moduleka heerka ITU-T G.959.1-2012-02 heerka. Module-ku wuxuu u beddelaa 4 kanaalada wax-soo-gelinta (ch) ee 25.78 Gbps ilaa 27.95Gbps xogta korantada ilaa 4 haad calaamadaha, wuxuuna ku dhuftaa hal kanaal oo loogu talagalay 100Gb/s gudbinta indhaha. Taa beddelkeeda, dhinaca qaataha, moduleka si indho-sarcaad ah ayaa u-multiplexes 100Gb/s u gelinaya 4 calaamadood oo haad ah, wuxuuna u beddelaa 4 haad oo soo saara xogta korantada. Mawjadaha dhexe ee 4ta haad waa 1296 nm, 1300 nm, 1305 nm iyo 1309 nm. Waxay ka kooban tahay iskuxiraha LC-ga laba-geesoodka ah ee isku-xirka indhaha iyo 38-pin xiriiriyaha korantada. Si loo yareeyo kala firdhisanaanta indhaha ee nidaamka jilitaanka dheer, fiber-hal-mode (SMF) waa in lagu dabaqaa cutubkan. Alaabta waxaa loo qaabeeyey iyadoo leh qaab, iskuxir indho-indheyn/koronto iyo isdhexgal ogaanshaha dhijitaalka ah sida uu qabo Heshiiska Ilaha-badan ee QSFP28 (MSA). Waxaa loo qaabeeyey si ay ula kulanto xaaladaha shaqada dibadda ee ugu adag oo ay ku jiraan heerkulka, qoyaanka iyo faragelinta EMI. Module-ku wuxuu ka shaqeeyaa hal +3.3V koronto iyo LVCMOS/LVTTL calaamadaha kontoroolka caalamiga ah sida Module Present, Dib-u-dejinta, Joojinta iyo Habka Awoodda Hoose ayaa la heli karaa modules-yada. Isku xirka 2-siliga ah ayaa diyaar ah si loo diro oo loo helo calaamadaha xakamaynta kakan iyo si loo helo macluumaadka ogaanshaha dhijitaalka ah. Kanaalada shaqsiga ah waa wax laga qaban karaa oo kanaalada aan la isticmaalin waa la xiri karaa dabacsanaanta naqshadeynta ugu badan. JHA-Q28C20 waxaa loo qaabeeyey iyadoo leh qaab, isku xirka indhaha/korontada iyo isdhexgalka ogaanshaha dhijitaalka ah sida uu qabo heshiiska QSFP28 Multi-source Agreement (MSA). Waxaa loo qaabeeyey si ay ula kulanto xaaladaha shaqada dibadda ee ugu adag oo ay ku jiraan heerkulka, qoyaanka iyo faragelinta EMI. Module-ku waxa uu bixiyaa hawlkarnimo aad u saraysa iyo is-dhexgal muuqaal ah, oo laga heli karo iyada oo loo sii marayo is-dhexgal laba-fire ah. • Calaamadda Halbeegga Qiimaynta ugu Sarreysa ee ugu sarreysa Min.
