Amanothi:
- I-TX Fault ingumqoqi ovulekile/okukhipha amanzi, okumele kudonswe ngesivimbeli esingu-4.7K–10KΩ ebhodini lomsingathi. Khuphula i-voltage phakathi kuka-2.0V ne-VccT, R+0.3V. Uma kuphezulu, okukhiphayo kubonisa iphutha le-laser lohlobo oluthile. Okuphansi kubonisa ukusebenza okuvamile. Esimeni esiphansi, okukhiphayo kuzodonselwa ku-<0.8V.
- I-TX disable okokufaka okusetshenziselwa ukuvala ukuphuma kwe-transmitter optical. Idonselwa phezulu ngaphakathi kwemojuli nge-resistor engu-4.7–10 KΩ. Izimo zayo yilezi:
Phansi (0 – 0.8V): I-Transmitter ivuliwe
(>0.8, < 2.0V): Akuchazwanga
Phezulu (2.0 – 3.465V): I-Transmitter Ikhubazekile
Vula: I-Transmitter Ikhutshaziwe
- I-Mod-Def 0,1,2. Lawa amaphinikhodi encazelo yemojuli. Kufanele zidonswe nge-4.7K - 10KΩ resistor ebhodini lomsingathi. I-voltage yokudonsa izoba yi-VccT noma i-VccR.
I-Mod-Def 0 isekelwe yimojuli ukukhombisa ukuthi imojuli ikhona
I-Mod-Def 1 iwumugqa wewashi we-serial interface yezintambo ezimbili ze-serial ID
I-Mod-Def 2 iwumugqa wedatha we-serial interface yezintambo ezimbili ze-serial ID
4. I-LOS (Ukulahlekelwa Kwesiginali) ingumqoqi ovulekile/okukhipha amanzi, okufanele kudonswe nge-resistor engu-4.7K - 10KΩ. Khuphula i-voltage phakathi kuka-2.0V ne-VccT, R+0.3V. Uma kuphezulu, lokhu okukhiphayo kubonisa ukuthi amandla okubona atholiwe angaphansi kokuzwela umamukeli wesimo esibi kakhulu (njengoba kuchazwe izinga elisetshenziswayo). Okuphansi kubonisa ukusebenza okuvamile. Esimeni esiphansi, okukhiphayo kuzodonselwa ku-<0.8V.
- I-VeeR ne-VeeT ingase ixhunywe ngaphakathi ngaphakathi kwemojula ye-SFP.
- I-RD-/+: Lena imiphumela yomamukeli ohlukile. Ayi-DC ahlanganiswe imigqa ehlukile engu-100Ω okufanele inqanyulwe ngo-100Ω (umehluko) kumsebenzisi ongu-SERDES.
- I-VccR ne-VccT yizinto ezinikezwa amandla ezitholayo kanye nezidlulisi. Achazwa ngokuthi 3.3V ±5% kuphinikhodi yesixhumi se-SFP. Umthamo omkhulu wamanje ngu-450mA. Ukuhlunga okunconyiwe kwebhodi lomsingathi kuboniswa ngezansi. Ama-inductors anokumelana ne-DC okungaphansi kuka-1Ω kufanele asetshenziswe ukuze kugcinwe i-voltage edingekayo ephinikhodi yokufaka ye-SFP ene-voltage yokunikezela engu-3.3V. Uma kusetshenziswa inethiwekhi enconyiwe yokuhlunga okuhlinzekwayo, ukuxhunywa okushisayo kwemojula ye-transceiver ye-SFP kuzophumela ku-inrush current engekho ngaphezu kuka-30 mA enkulu kunevelu yesimo esizinzile. I-VccR ne-VccT ingase ixhunywe ngaphakathi ngaphakathi kwemojula ye-transceiver ye-SFP.
- I-TD-/+: Lawa ama-transmitter ahlukile. Ziyimigqa ehlanganisiwe ye-AC, ehlukile ene-100Ω yokunqanyulwa okuhlukile ngaphakathi kwemojuli. Ukuhlanganisa i-AC kwenziwa ngaphakathi kwemojuli futhi ngaleyo ndlela akudingekile ebhodini lomsingathi.

Izicelo Zomkhiqizo
I-GEPON OLT Yesicelo se-P2MP
Okujwayelekile
I-transceiver ye-HDV ZL5432099-ICS esekela isilinganiso sedatha evamile engu-1.25 Gbps yohlelo lokusebenza lwe-GEPON OLT kufika ku-20km ibanga lokudlulisela, iklanyelwe ukuhlangana nezimfuneko zobuchwepheshe ze-China Telecom EPON V2.1 1000BASE-PX20+. I-SC rececptacle eyesixhumi esibonakalayo esibonakalayo.
Imojula ihlinzeka ngemininingwane yokuxilonga yedijithali yezimo zayo zokusebenza nesimo, okuhlanganisa amandla okudlulisa, ukuchema kwe-laser, amandla okubona okufakwayo owamukelayo, izinga lokushisa lemojula, kanye nogesi wokunikezela. Idatha yokulinganisa ne-alamu/isexwayiso ibhalwe futhi igcinwe kumemori yangaphakathi (EEPROM). Imephu yememori iyahambisana ne-SFF-8472, njengoba kuboniswe ku-Fig. 2. Idatha yokuxilonga ingamanani we-A/D eluhlaza futhi kufanele iguqulelwe kumayunithi omhlaba wangempela kusetshenziswa ama-calibration constants agcinwe ezindaweni ze-EEPROM 56 - 95 ku-A2h.
