Amanqaku:
1. Xa iphezulu, le mveliso ibonisa impazamo yelaser yohlobo oluthile. Iphantsi ibonisa ukusebenza okuqhelekileyo. Kwaye kufuneka itsalwe phezulu nge-resistor ye-4.7 - 10KΩ kwibhodi yokusingatha.
2. I-TX disable yi-input esetyenziselwa ukuvala i-transmitter optical output. Itsalwa ngaphakathi kwi-module nge-resistor ye-4.7 - 10KΩ. Iimeko zayo zezi:
Phantsi (0 – 0.8V): I-transmitter ivuliwe (>0.8, <2.0V): Ayichazwanga
Phezulu (2.0V ~ Vcc + 0.3V): I-Transmitter Ikhutshaziwe Ivuliwe: I-Transmitter Ikhutshaziwe
3. Mod-Def 0,1,2. Ezi ziiphini zenkcazelo yemodyuli. Zifanele zitsalwe phezulu nge-resistor ye-4.7K – 10KΩ kwibhodi yomncedisi. I-voltage yokutsalwa phezulu mayibe phakathi kwe-2.0V ~ Vcc + 0.3V.
I-Mod-Def 0 isekelwe yimodyuli ukubonisa ukuba imodyuli ikhona
I-Mod-Def 1 ngumgca wewotshi we-interface ye-serial ye-wire ezimbini ye-serial ID
I-Mod-Def 2 ngumgca wedatha we-interface ye-serial ye-wire ezimbini ye-serial ID
4. Xa iphezulu, le mveliso ibonisa ukulahleka kwesiginali (LOS). Ephantsi ibonisa ukusebenza okuqhelekileyo.
5. RD+/-: Ezi ziziphumo ze-differential receiver. Zii-AC ezidityanisiweyo ze-100Ω imigca ye-differential ekufuneka iphele nge-100Ω (differential) kwi-SERDES yomsebenzisi. I-AC coupling yenziwa ngaphakathi kwimodyuli kwaye ke ngoko ayifuneki kwibhodi yomsingathi.
6. TD+/-: Ezi zi-differential transmitter inputs. Zidibene ne-AC, imigca eyahlukeneyo ene-100Ω differential termination ngaphakathi kwemodyuli. I-AC coupling yenziwa ngaphakathi kwemodyuli kwaye ke ngoko ayifuneki kwibhodi yomsingathi.
