摘要: An office-side optical burst receiving apparatus in for example an PON transmission system which solves the problem of reception failure due to a low frequency response, constituted by being provided with pre-amplifier circuit amplifying output from light element, main amplifier signal thereof and threshold value as differential inputs discriminating logics "1" "0", control having level detection "0" signal, memory/calculation updating storing regarding detected logic whenever cell is received. It further contains adder defines substantially half difference levels value, adds now received stored level, applies added circuit.
