Izalathi zefrikhwensi yerediyo engenazingcingo ziquka ikakhulu ezi ndawo zilandelayo:
1. Ukuhambisa amandla
2. Ubungakanani be vector yempazamo (EVM)
3. Impazamo yokuphindaphinda
4. Ithemplethi ye-Frequency offset yokuhambisa iimpawu
5. I-Spectrum flatness
6. Ukufumana ubuntununtunu
Amandla othumelo abhekisa kumandla okusebenza e-eriyali yothumelo lwemveliso engenazingcingo, kwi-dBm.Amandla okuhanjiswa kwamacingo amisela amandla kunye nomgama wesignali engenazingcingo, kwaye amandla aphezulu, umqondiso womelele.
I-Error Vector Manitude (EVM) sisalathisi esiqwalasela umgangatho weempawu ezihlengahlengisiweyo, ezilinganiswe kwi-dB.Incinci i-EVM, ingcono umgangatho wesignali.Ithemplate ye-frequency offset yesiginali edlulisiweyo inokulinganisa umgangatho wesiginali egqithisiweyo kunye nokukwazi kwayo ukucinezela ukuphazamiseka kumajelo akufutshane.
I-template ye-spectrum encinci kunye nokude umgca wetemplate eqhelekileyo, ngcono ukusebenza kwayo phantsi komqathango wokuba amandla okuhambisa adibana nayo.Kunye nolwamkelo lolwamkelo: iparameter ebonisa ukusebenza kolwamkelo lwento evavanyiweyo.Okukhona ulwamkelo lolwamkelo lungcono, kokukhona luluncedo ngakumbi iimpawu ezilufumanayo, kwaye kokukhona lukhudlwana uluhlu lwayo lokhuselo olungenazingcingo.
Okwangoku, iimveliso zethu zezixhobo zenethiwekhi zihlukeneyo: zihlakaniphilewena, imodyuli ye-optical yonxibelelwano, imodyuli ye-fiber optical, imodyuli ye-sfp optical, izixhobo ze-olt, i-Ethernet switch, njl. Ukuba ufuna, unokuba nokuqonda okunzulu.
