    GPON OLT B+ Optical Module 2.5G/1.25G 20KM TX1490nm/RX1310nm GPON SFP

    Kufotokozera Kwachidule:

    Zogulitsa:

     Thandizani ntchito ya ITU-T G.984.2 GPON OLT B+

    Maulalo a data amtundu umodzi wokhala ndi ma symmetric 2.488Gbps Tx ndi 1.244Gbps Rx

     1490nm yopitilira-mode transmitter yokhala ndi DFB LD

     Wolandila wa 1310nm wophulika wokhala ndi APD-TIA

     2-waya mawonekedwe kwa Integrated digito diagnostic Monitoring

     Receiver RESET, Signal Detect, RSSI ntchito yosonyeza (RESET, RX_SD, RSSI)

     Phukusi la SFP lokhala ndi mawonekedwe owoneka bwino a SC/UPC

     Mphamvu imodzi + 3.3V

     Ntchito mlandu -40 ~ 85 ° C kwa mafakitale ndi 0 ~ 70 ° C malondaRoHS6 kutsatira
