Zvinyorwa:
1. Kana yakakwira, kubuda uku kunoratidza kuti pane laser fault yerudzi rwakati. Kuderera kunoratidza kushanda kwakajairika. Uye kunofanira kudhonzwa kumusoro ne 4.7 - 10KΩ resistor pabhodhi remubati.
2. TX disable chinhu chinoshandiswa kudzima transmitter optical output. Chinodhonzwa mukati memodule ne 4.7 - 10KΩ resistor. Mamiriro acho ndeaya:
Yakaderera (0 – 0.8V): Chinotumira chiri pa (>0.8, < 2.0V): Chisina kujeka
Yakakwira (2.0V~Vcc+0.3V): Chinotakurisa chakaremara Yakavhurika: Chinotakurisa chakaremara
3. Mod-Def 0,1,2. Aya ndiwo mapini etsanangudzo yemodule. Anofanira kudhonzwa ne resistor ye4.7K - 10KΩ pabhodhi rehost. Voltage yekudhonza-kumusoro inofanira kuva pakati pe2.0V ~ Vcc + 0.3V.
Mod-Def 0 yakasimbiswa ne module kuratidza kuti module iripo
Mod-Def 1 ndiyo mutsetse wewachi wewaya mbiri dzekubatanidza serial ye serial ID
Mod-Def 2 ndiyo data line ye two wire serial interface ye serial ID
4. Kana yakakwira, kubuda uku kunoratidza kurasikirwa kwechiratidzo (LOS). Kuderera kunoratidza kushanda kwakajairika.
5. RD+/-: Aya ndiwo ma "differential receiver outputs". Aya ndiwo ma "AC" akabatana ne100Ω differential lines ayo anofanira kugumiswa ne100Ω (differential) paSERDES yemushandisi. Kubatanidzwa kweAC kunoitwa mukati memodule uye nekudaro hakudiwi pabhodhi remugamuchiri.
6. TD+/-: Aya ndiwo ma "differential transmitter inputs". Akabatanidzwa neAC, mitsetse yakasiyana ine 100Ω differential termination mukati memodule. Kubatanidzwa kweAC kunoitwa mukati memodule uye nekudaro hakudiwi pabhodhi rekugamuchira.
