Ngaba ukwimarikeI-40G QSFP + iintambo zokuqhawulakodwa awuqinisekanga ukuba yeyiphi inketho ekulungeleyo?Ngokhetho oluninzi phaya, kunokuba nzima ukwazi ukuba yeyiphi eyona ilungele iimfuno zakho zesixhobo sokunxibelelana.Kwesi sithuba sebhlog, siza kuphonononga umahluko phakathi kwe-fiber optic cabling, intambo yobhedu encamathele ngokuthe ngqo (DAC), kunye nentambo yokukhanya esebenzayo (AOC) ukukunceda wenze isigqibo esinolwazi.
Xa kuziwa ekudibaniseni i-network device ye-QSFP + izibuko ukufezekisa i-40G Ethernet amanani edatha, kukho iindlela ezimbini eziphambili.Inketho nganye ineenzuzo zayo kunye nezilumkiso ekufuneka ziqwalaselwe.Indlela ekhethiweyo ekhethiweyo iya kuxhomekeka kwizinto ezifana neendleko, umgama wothumelo, ukuguquguquka kweentshukumo kunye notshintsho oluzayo, kunye nendawo yokubeka umzimba.
Into yokuqala ekufuneka uyiqwalasele ngumgama woqhagamshelo lwezibuko.Ngokuxhomekeke kumgama, ezinye iinketho zisenokungenzeki.Ngokomzekelo, umgama wothumelo lwekhebula le-DAC ukhawulelwe kwi-10m, efanelekileyo kakhulu ukudibanisa umgama omfutshane.Kwelinye icala, ikhebula le-AOC linoluhlu lothumelo oluya kuthi ga kwi-150m, libonelela ngenketho ebhetyebhetye ngakumbi kumgama omde.Nangona kunjalo, njengoko imigama ithatha ixesha elide, kubalulekile ukuqwalasela ubuchule bokufaka iintambo ezineemodyuli ezigxininiswe ekupheleni kweetreyi zentambo ezide okanye i-raceways ephantsi.
Xa ukhetha i-40G QSFP + ikhebula lokuqhawula ikhebula kwisixhobo sakho sothungelwano, indleko yinto ebalulekileyo yokuqwalasela.Iintambo zeDAC zidla ngolona khetho lungabizi kakhulu, nto leyo ezenza zibe lukhetho oludumileyo kuqhagamshelo lomgama omfutshane kuhlahlo lwabiwo-mali.I-Fiber optic cabling, kwelinye icala, ithande ukubiza kakhulu kodwa inika ukuguquguquka okukhulu kunye nemigama emide yothumelo.Iindleko zeentambo ze-AOC ziphakathi nendawo, ziyenza i-compromise elungileyo phakathi kwe-DAC kunye ne-fiber optic options.
Xa ukhetha i-40G QSFP + iintambo zokuqhawula, kufuneka uphinde ucinge ngendawo ye-port kunye nendawo ekhoyo ye-rack ebonakalayo.Umzekelo, iintambo zeDAC zihlala zibhetyebhetye kwaye kulula ukuzilawula kwiindawo ezixineneyo, zizenza zilungele ukudityaniswa ngaphakathi kwirack efanayo.Kwelinye icala, iFiber optic cabling ifuna ukuphathwa ngononophelo kwaye inokulungela ngcono umgama omde kunye nofakelo olusisigxina.
Isishwankathelo, i-40G efanelekileyo ye-QSFP + ikhebula lokuqhawula izixhobo zakho zenethiwekhi ixhomekeke kwizinto ezahlukeneyo, kubandakanywa iindleko, umgama wokuhambisa, ukuguquguquka kokuhamba kwexesha elizayo kunye neenguqu, indawo ye-port, kunye nendawo yokubeka umzimba.Ngokuqonda iiyantlukwano phakathi kwe-fiber optic cabling, intambo yobhedu ye-copper (DAC), kunye nekhebula elisebenzayo elibonakalayo (AOC), unokwenza izigqibo ezinolwazi kwiimfuno ezithile zenethiwekhi yakho.Nokuba ubeka phambili ukusebenza kakuhle kweendleko, ukuguquguquka okanye ukuqhagamshelwa kude, kukho isisombululo esifanele iimfuno zakho.
