Notes:
1. TX Fault ndeye yakavhurika muunganidzi yakabuda, iyo inofanirwa kudhonzwa kumusoro ne 4.7k ~ 10kΩ resistor pane host board kune voltage pakati pe2.0V neVcc+0.3V. Logic 0 inoratidza kushanda kwakajairika; logic 1 inoratidza laser kukanganisa kweimwe mhando. Mune yakaderera mamiriro, iyo inobuda ichadhonzwa kune isingasviki 0.8V.
2. TX Disable inhomendi inoshandiswa kudzima transmitter optical output. Iyo inodhonzwa kumusoro nemodule ine 4.7k ~ 10kΩ resistor. Nyika dzayo dzinoti:
Yakaderera (0~0.8V): Transmitter on
(> 0.8V, <2.0V): Zvisina kutsanangurwa
High (2.0~3.3V): Transmitter Yakaremara
Vhura: Transmitter Yakaremara
3. MOD-DEF 0,1,2 ndiwo mapini ekutsanangura module. Ivo vanofanirwa kudhonzwa ne 4.7k ~ 10kΩresistor pane iyo host board. Iyo yekudhonza-kumusoro voltage ichave VccT kana VccR.
MOD-DEF 0 yakavakirwa nemodule kuratidza kuti module iripo.
MOD-DEF 1 ndiyo mutsara wewachi maviri waya serial interface yeserial ID.
MOD-DEF 2 ndiyo mutsara wedata weviri waya serial interface yeserial ID.
4. LOS ndiyo yakazaruka muunganidzi yakabuda, iyo inofanira kukweverwa kumusoro ne 4.7k ~ 10kΩ resistor pane bhodhi rinogamuchira kune voltage pakati pe 2.0V neVcc + 0.3V. Logic 0 inoratidza kushanda kwakajairika; logic 1 inoratidza kurasikirwa kwechiratidzo. Mune yakaderera mamiriro, iyo inobuda ichadhonzwa kune isingasviki 0.8V.
5. Aya ndiwo akasiyana anogamuchira akabuda. Iwo emukati AC-akabatana 100Ω mitsara yekusiyanisa iyo inofanirwa kugumiswa ne100Ω (yakasiyana) pamushandisi SERDES.
6. Aya ndiwo mapindiro anosiyanisa transmitter. Iwo ari AC-akabatana, mitsara yekusiyanisa ine 100Ω musiyano wekugumiswa mukati memodule.
