Abstract: Disclosed are an impedance correcting method and apparatus, and an impedance-corrected signal line for an optical transceiver. The impedance correction method includes receiving an impedance according to an error of a resin applying process of a signal line for an optical transceiver, acquiring a correction parameter for generating a correction impedance based on the impedance according to the error, and determining the correction impedance for correcting the impedance according to the error based on the correction parameter.
