Ukuphishekela enkampanini, kuzoba injabulo yamakhasimendeImodyuli engu-1.25G SFP, Imodyuli ye-China SFP, Ukwaneliseka kanye nesikweletu esihle kuwo wonke amakhasimende kuyinto eza kuqala kithi. Sigxila kuyo yonke imininingwane yokusebenza kwe-oda kumakhasimende aze athole izimpahla eziphephile nezinomsindo ngensizakalo enhle yokungena kanye nezindleko zezomnotho. Ngokuya ngalokhu, izimpahla zethu zithengiswa kahle emazweni ase-Afrika, maphakathi no-Eastast Asia.

Umdwebo osebenzayo

Izilinganiso eziphezulu ngokuphelele

Qaphela: Ukuxineka ngokweqile kwezilinganiso eziphezulu ngokuphelele kungadala ukulimala okungapheli ku-transceiver.

Izici ezijwayelekile zokusebenza

Izici zikagesi (phezulu (c) = 0 kuya ku-70 ℃, phezulu (i) = -40 kuya ku-85 ℃, vcc = 3.1 v) ku-3.47 v)

Amanothi:

1. I-TD +/- iyi-anctionally ac kuhlanganiswe ngokuqedwa kwe-100 ω okuhlukile ngaphakathi kwemodyuli.

2. Iphutha le-TX ne-RX Los yi-Open Collector Output, okufanele idonswe ngo-4.7k kuya ku-10k. Donsela amandla kagesi phakathi kwe-2.0V ne-VCC + 0.3V.

I-3. I-RD +/- Ukuphuma kwangeni ngaphakathi kwe-AC kuhlanganiswe, futhi kufanele kunqanyulwe nge-100ω (ehlukile) kuma-serdes omsebenzisi.

Izici ze-Optical (Phezulu (C) = 0 kuya ku-70 ℃, phezulu (I) = -40 kuya ku-85 ℃, VCC = 3.13 v)

Amanothi:

1. Kukalwa ku-1.25GB / S nge-PRBS 2 2^{23 - 1}Iphethini yokuhlola ye-NRZ.

2. Ongafakwanga, kulinganiswe nge-PRBS2^{23 - 1}iphethini yokuhlola @ 1.25gbps

3. Kukalwa ku-1.25GB / S nge-PRBS 2^{23 - 1}Iphethini yokuhlola ye-NRZ ye-BER <1 × 10^-12

Izincazelo zePin nemisebenzi

Amanothi:

1. Lapho ephezulu, lo mphumela ukhombisa iphutha le-laser lohlobo oluthile. Okuphansi kukhombisa ukusebenza okujwayelekile. Futhi kufanele idonswe nge-4.7 - 10k Resistoor on the Host Board.

2. I-TX Khubaza ukufakwa okusetshenziselwa ukuvala ukuphuma kwe-transmitter akhipha. Kudonswa ngaphakathi kwemodyuli nge-4.7 - 10k Resistor. Izifundazwe zalo yilezi:

Okuphansi (0 - 0.8v): Transmitter on (> 0.8, <2.0V): AKUFUNI

I-High (2.0V ~ VCC + 0.3V): I-Transmitter ikhutshaziwe i-Open: Transmitter ikhutshaziwe

3. Mod-def 0,1,2. Lezi izikhonkwane zencazelo ye-module. Kufanele zidonswe nge-4.7k - 10k-Shess Resistor ebhodini elisingathi. I-voltage yokudonsela phezulu izoba phakathi kwe-2.0V ~ VCC + 0.3V.

I-Mod-def 0 isuswe yimodyuli ukukhombisa ukuthi imodyuli ikhona

I-Mod-def 1 ingumugqa wewashi we-wire serial interface ye-id ye-serial

I-Mod-def 2 umugqa wedatha we-wire serial interface ye-id ye-serial

4. Lapho ephezulu, lokhu kukhipha kukhombisa ukulahleka kwesiginali (los). Okuphansi kukhombisa ukusebenza okujwayelekile.

I-5. I-RD +/-: Lokhu kungukuphuma kokwehlukahluka okuhlukile. Ziyi-ac ehlanganisiwe eyi-100 ω ezihlukile okufanele zinqanyulwe nge-100ω (ezehlukene) kuma-sierdes omsebenzisi. Ukuhlangana kwe-AC kwenziwa ngaphakathi kwemodyuli futhi ngakho-ke akudingeki ebhodini lokusingathwa.

6. I-TD +/-: Lokhu kungukufakwa kokudluliselwa kwe-transmitter. Ziyimigqa ehlanganisiwe ye-AC Ukuhlangana kwe-AC kwenziwa ngaphakathi kwemodyuli futhi ngakho-ke akudingeki ebhodini lokusingathwa.

Ukucaciswa kwedijithali

Izinguqulo zingasetshenziswa ezinhlelweni zokusingathwa ezidinga ukuxilongwa kwedijithali ngaphakathi noma ngaphandle kwangaphandle.

Amanothi:

1.Wakha i-temp. = 0 ~ 70 ºC, uhla luzoba min = -5, max = + 75

2. Ukunemba kwe-TX BIAS yamanje kungu-10% we-permate yamanje kusuka kumshayeli we-laser uye e-laser

3. Ukulinganisa kwangaphakathi / kwangaphandle okuhambisanayo.
