Amanqaku:
1. I-TX Fault yimveliso evulekileyo yomqokeleli, ekufuneka itsalwe phezulu kunye ne-4.7k ~ 10kΩ resistor kwibhodi yokusingatha kwi-voltage phakathi kwe-2.0V kunye neVcc + 0.3V. I-Logic 0 ibonisa ukusebenza okuqhelekileyo; I-logic 1 ibonisa impazamo ye-laser yohlobo oluthile. Kwimeko ephantsi, imveliso iya kutsalwa ibe ngaphantsi kwe-0.8V.
2. I-TX Khubaza igalelo elisetyenziselwa ukuvala i-transmitter optical output. Itsalwa phezulu kunye nemodyuli ene-4.7k ~ 10kΩ resistor. Iimeko zayo zezi:
Phantsi (0~0.8V): Isidluliseli sivuliwe
(>0.8V, <2.0V): Akuchazwanga
Phezulu (2.0 ~ 3.3V): I-Transmitter ikhubazekile
Vula: IsiThuthi sikhubazekile
3. MOD-DEF 0,1,2 zizikhonkwane zenkcazo yemodyuli. Kufuneka batsalwe phezulu nge-4.7k~10kΩresistor kwibhodi yokusingatha. Umbane wokutsalela phezulu uya kuba yiVccT okanye iVccR.
I-MOD-DEF 0 isekelwe kwimodyuli ukubonisa ukuba imodyuli ikhona.
I-MOD-DEF 1 yilayini yewotshi yojongano lweengcingo ezimbini zothotho lwe-ID yothotho.
I-MOD-DEF 2 yilayini yedatha yojongano lweengcingo ezimbini ze-serial ID.
4. I-LOS yimveliso evulekileyo yomqokeleli, ekufuneka ikhutshwe kunye ne-4.7k ~ 10kΩ resistor kwibhodi yokusingatha ukuya kumbane phakathi kwe-2.0V kunye neVcc + 0.3V. I-Logic 0 ibonisa ukusebenza okuqhelekileyo; I-logic 1 ibonisa ukulahleka komqondiso. Kwimeko ephantsi, imveliso iya kutsalwa ibe ngaphantsi kwe-0.8V.
5. Ezi ziziphumo zomamkeli ohlukeneyo. Ngaphakathi AC-dityaniswe 100Ω imigca eyahlukileyo ekufuneka ipheliswe nge-100Ω (umahluko) kumsebenzisi we-SERDES.
6. La ngamagalelo othungelwano olwahlukileyo. Ziyi-AC-dityanisiwe, imigca eyahlukileyo kunye ne-100Ω ukupheliswa kokwahlukana ngaphakathi kwimodyuli.
