Inyandiko:
- TX Ikosa ni ikusanyirizo rifunguye / risohora amazi, rigomba gukururwa hamwe na 4.7K - 10KΩ résistor ku kibaho. Kuramo voltage hagati ya 2.0V na VccT, R + 0.3V. Iyo hejuru, ibisohoka byerekana laser amakosa yubwoko runaka. Hasi yerekana imikorere isanzwe. Muri leta yo hasi, ibisohoka bizakururwa kuri <0.8V.
- TX disable niyinjiza ikoreshwa muguhagarika transmitter optique isohoka. Ikururwa muri module hamwe na 4.7-10 KΩ irwanya. Ibihugu byayo ni:
Hasi (0 - 0.8V): Kohereza kuri
(> 0.8, <2.0V): Ntisobanuwe
Hejuru (2.0 - 3.465V): Ikimuga cyahagaritswe
Fungura: Ikwirakwizwa ryahagaritswe
- Mod-Def 0,1,2. Nibisobanuro byerekana module. Bagomba gukururwa hamwe na 4.7K - 10KΩ résistor ku kibaho. Umuvuduko ukurura ugomba kuba VccT cyangwa VccR.
Mod-Def 0 ishingiye kuri module kugirango yerekane ko module ihari
Mod-Def 1 numurongo wisaha yibice bibiri byuruhererekane rwindangamuntu
Mod-Def 2 numurongo wamakuru wibice bibiri byuruhererekane rwindangamuntu
4. GUTAKAZA (Gutakaza Ikimenyetso) ni ugukusanya / gusohora amazi, bigomba gukururwa hamwe na 4.7K - 10KΩ. 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.
- VeeR na VeeT birashobora guhuzwa imbere muburyo bwa SFP.
- RD - / +: Ibi nibisubizo bitandukanye byo kwakira. Ni DC ihujwe 100Ω imirongo itandukanye igomba guhagarikwa na 100Ω (itandukaniro) kumukoresha SERDES.
- VccR na VccT nizo zakira kandi zitanga amashanyarazi. Basobanuwe nka 3.3V ± 5% kuri pin ya SFP. Amashanyarazi ntarengwa ni 450mA. Basabwe kwakira abategetsi amashanyarazi yo kuyungurura irerekanwa hepfo. Inductor zifite imbaraga za DC ziri munsi ya 1Ω zigomba gukoreshwa kugirango zigumane ingufu zisabwa kuri pin ya SFP yinjiza hamwe na 3.3V itanga amashanyarazi. Iyo imiyoboro isabwa yo kuyungurura ikoreshwa, gucomeka bishyushye bya SFP transceiver module bizavamo inrush yumuvuduko utarenze 30 mA urenze agaciro ka leta gahamye. VccR na VccT birashobora guhuzwa imbere muburyo bwa SFP transceiver module.
- TD - / +: Izi ninyandiko zinyuranye zohereza. Ni AC-ihujwe, imirongo itandukanye hamwe 100Ω itandukanyirizo imbere muri module. Guhuza AC bikorwa imbere muri module bityo ntibisabwa ku kibaho.

HDV ZL5432099-ICS transceiver ifite inkunga yamakuru ya 1.25 Gbps ya porogaramu ya GEPON OLT igera kuri kilometero 20 zoherejwe, yateguwe guhura nu Bushinwa Telecom EPON ibikoresho bya tekinike V2.1 1000BASE-PX20 + ibisobanuro. SC yakira ni ya optique.
Module itanga amakuru yo kwisuzumisha muburyo bwimikorere yimikorere nimiterere, harimo kohereza imbaraga, laser bias, imashini yinjiza optique, ubushyuhe bwa module, hamwe na voltage itanga. Calibration hamwe no gutabaza / kuburira amakuru yamakuru yanditse kandi abikwa mububiko bwimbere (EEPROM). Ikarita yo kwibuka irahujwe na SFF-8472, nkuko bigaragara ku gishushanyo cya 2. Amakuru yo kwisuzumisha ni indangagaciro mbisi A / D kandi agomba guhindurwa mubice nyabyo byisi ukoresheje kalibrasi yabitswe mubibanza bya EEPROM 56 - 95 muri A2h.
