Pali mitundu iwiri ya 100G AOC: 100G QSFP28 yogwiritsa ntchito chingwe cha AOC ndi 100G QSFP28 mpaka 4x25G SFP28 chingwe chogwira ntchito.Pali zolandila ma module optical kumapeto onse amagetsi.Lolani kufala kwa m'modzi-m'modzi.Chotsatiracho chili ndi zolumikizira za 100G QSFP28 pamapeto amodzi ndi zolumikizira zinayi za 25G SFP28 pamapeto ena, kupereka kutumiza kwa data kwa 100G kwa makasitomala.
2. Gulu la 100G lapamwamba kwambiri lamkuwa la DAC
Pali mitundu iwiri ya 100G yamkuwa yothamanga kwambiri DAC: 100G QSFP28 DAC yolumikizidwa mwachindunji ndi mkuwa ndi 100G QSFP28 mpaka 25G SFP28 DAC yolumikizidwa mwachindunji.Pali zolandila ma module optical kumapeto onse amagetsi.Lolani kufala kwa m'modzi-m'modzi.Chotsatiracho chili ndi zolumikizira za 100G QSFP28 pamapeto amodzi ndi zolumikizira zinayi za 25G SFP28 pamapeto ena, kupereka kutumiza kwa data kwa 100G kwa makasitomala.
Mafunso Okhudza 100G DAC/AOC Cables
Q: Kodi pali kusiyana kotani pakati pa 100G DAC ndi AOC?
A: 100G DAC imapangidwa ndi zingwe zamkuwa za Twinax zolumikizira mbali zonse ziwiri, pomwe 100G AOC ndi chingwe cha MMF chokhala ndi zolumikizira za SFP mbali zonse ziwiri.Pali zosiyana zingapo pakati pa zingwe ziwirizi.Kawirikawiri, 100G DAC imagwiritsa ntchito mphamvu zochepa ndipo imakhala yotsika mtengo kuposa 100G AOC.Mosiyana ndi izi, 100G AOC imathandizira magwiridwe antchito apamwamba pamtunda wotumizira komanso ndiyoyeneranso kutumizidwa kwa data center.Kuti mudziwe zambiri za kusiyana pakati pa zingwe za DAC ndi AOC, chonde werengani Data Center Cabling Solution: DAC Cables vs AOC Cables.
Q: Kodi kapangidwe ka 100G AOC ndi chiyani?
A: 100G AOC makamaka imakhala ndi ma module awiri a kuwala ndi chingwe chodumphira.Ma transceivers pamapeto onsewa amapangidwa ndi kutalika kosiyanasiyana kwa OM3 kapena OM4 multimode fiber.
Q: Kodi zingwe za 100G QSFP28 zingagwiritsidwe ntchito pa 40G?
A: Inde, zingwe za QSFP28 zitha kugwiritsidwa ntchito pa 40G, koma osati mosemphanitsa.Pali lamulo lokhudza kusakaniza ma transceivers optical pa liwiro losiyana: mapeto onse a ma modules awiriwa ayenera kugwirizana ndipo mawonekedwe a mawonekedwe amafunikanso kufanana.Kuphatikiza apo, liwiro la doko liyenera kukhala lofanana kapena lalikulu kuposa mawonekedwe ogwiritsidwa ntchito.
Q: Kodi njira yodutsira chingwe cha QSFP28 imatanthauza chiyani?
A: Njira yopuma imatanthawuza kuyendetsa doko la 100G monga 4 njira zosiyana za 25G kapena 2 njira zosiyana za 50G.Mukatulutsa doko limodzi la 100G kupita ku 4x 25G kapena 2x 50G maulalo, mawonekedwe a Forward Error Correction (FEC) pamapeto onse a ulalo ayenera kukhala ofanana kuti atsimikizire kulumikizana.
Q: Kodi makasitomala angagwiritse ntchito Chingwe cha QSFP28 chachitatu?
A: Inde, zingwe zamkuwa za 100G za chipani chachitatu zingagwiritsidwe ntchito koma zingwe zonse zimafunikira kuti zigwirizane ndi zomwe IEEE zimafunikira, komanso mawonekedwe a SFF-8636 / EEPROM kuti azitha kuzindikirika ndikuzindikiridwa ndi chosinthira/rauta.
