Embodiments of the present disclosure provide a delay measurement method and an optical transport network device. The method includes: acquiring, according to delay information from a first optical transport network device to a second optical transport network device in an optical transport network, a delay of transporting service data from the first optical transport network device to the second optical transport network device; adjusting, according to the delay, residence time of the service data in the optical transport network so that the time is equal to a preset reference delay. Through the method of the present disclosure, uplink and downlink delays can be accurately measured, and the residence time of the service data in the optical transport network is adjusted to be consistent with the reference delay, thereby solving the problem in the prior art of inaccurate delay measurement resulting from asymmetry between uplink and downlink delays.
