■ Cov SFP transceivers muaj kev ua tau zoo, cov nqi siv tau zoo txhawb cov ntaub ntawv-tus nqi ntawm 1.25Gbps thiab 550m kis tau tus mob nrog MMF.
■ Lub transceiver muaj peb ntu: VCSEL laser transmitter, PIN photodiode integrated nrog trans-impedance preamplifier (TIA) thiab MCU tswj chav tsev. Tag nrho cov modules txaus siab rau chav kawm I laser kev nyab xeeb.
■Cov transceivers yog sib xws nrog SFP Multi-Source Agreement (MSA) thiab SFF-8472. Yog xav paub ntxiv, thov xa mus rau SFP MSA.
