Lub module txhawb 1000 Mbps tag nrho duplex cov ntaub ntawv txuas nrog 5-theem Pulse Amplitude Modulation (PAM) cov teeb liab. Tag nrho plaub khub hauv cable yog siv nrog cov cim tus nqi ntawm 250Mbps ntawm txhua khub. Lub module muab cov ntaub ntawv xov xwm serial ID raws li SFP MSA, uas tuaj yeem nkag tau nrog qhov chaw nyob ntawm A0h ntawm 2wire serial CMOS EEPROM raws tu qauv. Lub cev IC kuj tuaj yeem nkag tau los ntawm 2wire serial tsheb npav ntawm qhov chaw nyob A0h.
