    1.25g Sfp Imodyuli 1310nm/1490(1550)nm Bidi Sfp Transceiver 40km Sfp Imodyuli eneDdm

    Inkcazelo emfutshane:

     Iphakheji ye-SFP enemithombo emininzi ene-LC / PC enye yokufumana;

     Imowudi enye ifayibha enye i-bi-directional transmission

    Ukuya kuthi ga kwi-10 ~ 120Km kunye ne-9/125μm SMF;

    I-AC idityaniswe ye-Rx kunye ne-Tx icala

    0 °C ukuya +70 °C kwinqanaba lezorhwebo, -40 °C ukuya +85 °C kwinqanaba lemizi-mveliso;

     Isebenza kwireyithi yedatha ye-1.25Gbps

     Ihambelana ne-MIL-STD-883/GR-468

    Amanqaku:
    1. Umhlaba wesekethe wodwa ngaphakathi kumhlaba we-chassis.
    2. TFAULTis umqokeleli ovulekileyo / imveliso yokukhupha, ekufuneka itsalwe phezulu kunye ne-4.7k - 10k Ohms resistor kwibhodi yokusingatha ukuba inenjongo
    ukusetyenziswa. Ukutsala amandla ombane kufuneka abe phakathi kwe-2.0V ukuya kwiVcc + 0.3V. Imveliso ephezulu ibonisa impazamo yothumelo ebangelwa nokuba kukuthambekela kwe-TX
    yangoku okanye amandla emveliso yeTX agqitha i-alarm esetwe kwangaphambili. Imveliso ephantsi ibonisa ukusebenza okuqhelekileyo. Kwimeko ephantsi, i
    imveliso itsalwa ukuya kwi-2.0V okanye ivuliwe, yenziwe kwi-TDIS <0.8V.
    4. Kufuneka itsalwe phezulu nge-4.7k - 10 kohms kwi-host board ukuya kumbane ophakathi kwe-2.0V kunye ne-3.6V.
    MOD_DEF(0) itsala umgca osezantsi ukubonisa imodyuli iplagiwe.
    5. I-LOS yimveliso evulekileyo yomqokeleli. Kufuneka itsalwe phezulu nge-4.7k - 10 kohms kwi-host board ukuya kumbane ophakathi kwe-2.0V kunye ne-3.6V. Ingqiqo 0
    ibonisa ukusebenza okuqhelekileyo; I-logic 1 ibonisa ukulahleka komqondiso.
