COV LUS Piav Qhia
Cov SFP transceivers yog cov khoom siv ua haujlwm siab, cov nqi tsim nyog uas txhawb nqa cov ntaub ntawv-nqi ntawm 1.25Gbps thiab 10KM kis nrug nrog SMF.
Lub transceiver muaj peb ntu: lub FP laser transmitter, lub PIN photodiode sib xyaw nrog lub trans-impedance preamplifier (TIA) thiab MCU tswj unit. Tag nrho cov modules ua tau raws li chav kawm I laser kev nyab xeeb cov kev cai.
Cov transceivers no sib xws nrog SFP Multi-Source Agreement (MSA) thiab SFF-8472. Yog xav paub ntxiv, thov mus saib SFP MSA.
