Inyandiko:
Gucomeka Seq.: Gukurikirana Pin mugihe gikurikiranye.
1) Ikosa rya TX ni ikusanyirizo rifunguye risohoka, rigomba gukururwa hamwe na 4.7k ~ 10kΩ résistor ku kibaho cyakira kugeza kuri voltage iri hagati ya 2.0V na Vcc + 0.3V. Logic 0 yerekana imikorere isanzwe; logique 1 yerekana lazeri ikosa ryubwoko runaka. Muri reta yo hasi, ibisohoka bizakururwa munsi ya 0.8V.
2) TX Disable niyinjiza ikoreshwa muguhagarika transmitter optique isohoka. Ikururwa muri module hamwe na 4.7 ¨C 10 K irwanya. Ibihugu byayo ni:
Hasi (0 kugeza 0.8V): Kohereza kuri
(> 0.8, <2.0V): Ntisobanuwe
Hejuru (2.0 kugeza 3.465V): Ikwirakwiza ryahagaritswe
Fungura: Ikwirakwizwa ryahagaritswe
3) Mod-Def 0,1,2. Nibisobanuro byerekana module. Bagomba gukururwa hamwe na 4.7K kugeza 10K birwanya kurubaho. Umuvuduko ukurura ugomba kuba VccT cyangwa VccR
Mod-Def 0 ishingiye kuri module kugirango yerekane ko module ihari

Mod-Def 2 numurongo wamakuru wibice bibiri byuruhererekane rwindangamuntu
4) GUTAKAZA (Gutakaza Ikimenyetso) nigisohoka gifungura / gusohora amazi, bigomba gukururwa hamwe na 4.7K kugeza 10K birwanya. Kuramo voltage hagati ya 2.0V na VccT, R + 0.3V. Iyo hejuru, ibisohoka byerekana imbaraga za optique zakiriwe ziri munsi yimikorere mibi yimikorere (nkuko bisobanurwa nibisanzwe mukoresha). Hasi yerekana imikorere isanzwe. Muri leta yo hasi, ibisohoka bizakururwa kuri <0.8V.
5) RD - / +: Ibi nibisubizo bitandukanye byo kwakira. Ni AC ihujwe n'imirongo 100 itandukanye igomba guhagarikwa na 100 (itandukanye) kumukoresha SERDES.
6) TD - / +: Izi ninyandiko zinyuranye zohereza. Nibintu AC-bifatanije, imirongo itandukanye hamwe 100 yo gutandukanya imbere muri module.
