Abstract
A burst optical signal receiving device is provided, which includes an optical receiving component and a limiting amplifying circuit unit. The optical receiving component further includes a photodetector, a trans-impedance amplifier, a first direct current (DC) cancellation forbidding circuit, and a DC bias circuit, and the limiting amplifying circuit unit further includes a group of alternating current (AC) coupling capacitors, a limiting amplifier, and a second DC cancellation forbidding circuit. Through the technical solution, an input burst optical signal within a certain dynamic range can be recovered into a valid burst electric signal in shorter time. The technical solution can be applied in a burst optical signal receiver in a 10-Gigabit Ethernet passive optical network (10GEPON).
