Amanqaku:
- I-TX Fault ngumqokeleli ovulekileyo / imveliso yokukhupha, ekufuneka itsalwe phezulu kunye ne-4.7K-10KΩ resistor kwibhodi yokusingatha.Tsala amandla ombane phakathi kwe-2.0V kunye neVccT, R+0.3V.Xa iphezulu, imveliso ibonisa impazamo ye-laser yolunye uhlobo.Okuphantsi kubonisa ukusebenza okuqhelekileyo.Kwimeko ephantsi, imveliso iya kutsalwa ku-<0.8V.
- I-TX disable ligalelo elisetyenziselwa ukuvala imveliso ye-transmitter optical.Itsalwa phezulu ngaphakathi kwimodyuli ene-4.7–10 KΩ resistor.Iimeko zayo zezi:
Phantsi (0 – 0.8V): Transmitter on
(>0.8, < 2.0V): Akuchazwanga
Phezulu (2.0 - 3.465V): I-Transmitter ikhubazekile
Vula: IsiThuthi sikhubazekile
- Mod-Def 0,1,2.Ezi zizikhonkwane zenkcazo yemodyuli.Kufuneka batsalwe phezulu nge-4.7K - 10KΩ resistor kwibhodi yokusingatha.Umbane wokutsalela phezulu uya kuba yiVccT okanye iVccR.
I-Mod-Def 0 isekelwe kwimodyuli ukubonisa ukuba imodyuli ikhona
I-Mod-Def 1 yilayini yewotshi yojongano lweengcingo ezimbini ze-serial ID
I-Mod-Def 2 yilayini yedatha ye-interface ye-serial ye-serial ye-serial ID
4. I-LOS (Ukulahleka kweSignali) ngumqokeleli ovulekileyo / ukukhutshwa kwe-drain, ekufuneka ikhutshwe kunye ne-4.7K - 10KΩ resistor.Tsala amandla ombane phakathi kwe-2.0V kunye neVccT, R+0.3V.Xa iphezulu, le mveliso ibonisa amandla optical afunyenweyo angaphantsi kweyona meko imbi kakhulu (njengoko kuchazwe ngumgangatho osetyenziswayo).Okuphantsi kubonisa ukusebenza okuqhelekileyo.Kwimeko ephantsi, imveliso iya kutsalwa ku-<0.8V.
- I-VeeR kunye ne-VeeT inokudibaniswa ngaphakathi ngaphakathi kwimodyuli ye-SFP.
- RD-/+: Ezi ziziphumo zomamkeli ohlukeneyo.Ziyi-DC ezidityaniswe ne-100Ω imigca eyohlukileyo ekufuneka ipheliswe nge-100Ω (umahluko) kumsebenzisi we-SERDES.
- I-VccR kunye ne-VccT ngamamkeli kunye nonikezelo lwamandla okuhambisa.Zichazwa njenge-3.3V ± 5% kwi-pin yokudibanisa i-SFP.Ubuninzi bokubonelela ngoku yi-450mA.Uhluzo lonikezelo lombane lwebhodi ecetyiswayo luboniswe ngezantsi.Ii-inductors ezinokumelana ne-DC ngaphantsi kwe-1Ω kufuneka zisetyenziswe ukuze kugcinwe i-voltage efunekayo kwi-SFP ye-input pin kunye ne-3.3V yombane wokubonelela.Xa kusetyenziswa inethiwekhi yokucoca unikezelo olucetyiswayo, iplagi eshushu yemodyuli ye-transceiver ye-SFP iya kubangela i-inrush current engekho ngaphezu kwe-30 mA enkulu kunexabiso lesimo esizinzileyo.I-VccR kunye ne-VccT inokudityaniswa ngaphakathi ngaphakathi kwimodyuli ye-transceiver ye-SFP.
- TD-/+: La ngamagalelo okuhambisa umahluko.Ziyi-AC-dityanisiwe, imigca eyahlukileyo kunye ne-100Ω ukupheliswa kokwahlukana ngaphakathi kwimodyuli.Ukudibanisa kwe-AC kwenziwa ngaphakathi kwimodyuli kwaye ngoko akufunwa kwibhodi yokusingatha.

Izicelo zeMveliso
I-GEPON OLT Yesicelo se-P2MP
Ngokubanzi
I-HDV ZL5432099-ICS i-transceiver enenkxaso yezinga ledatha ye-1.25 Gbps yesicelo se-GEPON OLT ukuya kwi-20km umgama wothumelo, iyilwe intlanganiso kunye ne-China Telecom EPON imfuno yobuchwepheshe ye-V2.1 1000BASE-PX20+ iinkcukacha.I-SC rececptacle yeyojongano olubonakalayo.
Imodyuli inikezela ngolwazi lokuxilonga idijithali yeemeko zayo zokusebenza kunye nobume, kubandakanywa amandla okuhambisa, i-laser bias, i-receiver input optical power, ubushushu bemodyuli, kunye nombane wokubonelela.Ukulinganisa kunye ne-alarm / isilumkiso sedatha ye-threshold ibhaliwe kwaye igcinwe kwimemori yangaphakathi (EEPROM).Imephu yememori iyahambelana ne-SFF-8472, njengoko kuboniswe kwi-Fig. 2. Idatha yokuxilonga i-A / D eluhlaza kwaye kufuneka iguqulelwe kwiiyunithi zehlabathi zangempela zisebenzisa i-containants calibration constants ezigcinwe kwiindawo ze-EEPROM 56 - 95 kwi-A2h.
