■ Lub SFP-BIDI transceivers yog kev ua haujlwm siab, cov nqi siv tau zoo txhawb nqa cov ntaub ntawv dual-tus nqi ntawm 1.25Gbps / 1.0625Gbps thiab 20km kis nrug nrog SMF.
■ Lub transceiver muaj peb ntu: DFB 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.
