Izinkomba zefrikhwensi yomsakazo ongenazintambo ikakhulukazi zihlanganisa amaphuzu alandelayo:
1. Amandla okudlulisa
2. Iphutha le-vector amplitude (EVM)
3. Iphutha lemvamisa
4. Isifanekiso se-frequency offset sokudlulisa amasignali
5. I-Spectrum flatness
6. Ukuthola ukuzwela
Amandla okudlulisa aqondise emandleni okusebenza othi lokudlulisela lomkhiqizo ongenazintambo, ku-dBm.Amandla okudlulisa okungenantambo anquma amandla nebanga lesiginali engenantambo, futhi amandla aphezulu, isignali iba namandla.
I-Error Vector Magnitude (EVM) inkomba ecabangela ikhwalithi yamasignali ashintshiwe, akalwa nge-dB.I-EVM encane, ingcono ikhwalithi yesiginali.Isifanekiso se-frequency offset yesiginali edlulisiwe singakala ikhwalithi yesiginali edlulisiwe kanye nekhono layo lokucindezela ukuphazamiseka eziteshini eziseduze.
Uma isifanekiso se-spectrum siba sincane futhi uba kude nolayini wesifanekiso esijwayelekile, kuba ngcono ukusebenza kwaso ngaphansi kwesimo lapho amandla okudlulisa ahlangana khona.Nokuzwela kokwamukela: ipharamitha ebonisa ukusebenza kokwamukela kwento ehloliwe.Ukuzwela kokwamukela okungcono kakhulu, amasiginali awusizo kakhulu ewatholayo, futhi kuba mkhulu ububanzi bayo bokuhlanganisa okungenantambo.
Njengamanje, imikhiqizo yethu yemishini yenethiwekhi ihlukene: ihlakaniphilewena, imojuli ye-optical yokuxhumana, imojula ye-fiber optical, i-sfp optical module, imishini ye-olt, i-Ethernet switch, njll. Uma udinga, ungaba nokuqonda okujulile.
