Abstract
Proposed is an operation method for two-way delay error compensation, the method including first to sixth steps. In the first step, a first wavelength is set as a signal wavelength for a master and a third wavelength is set as a signal wavelength for a slave. In the second step, first, second, third, and fourth time points are identified by using PTP. In the third step, a second wavelength is set as a signal wavelength for the master and the second wavelength is set for the slave. In the fourth step, fifth, sixth, seventh, and eighth time points are identified by using the PTP. In the fifth step, a delta value for a two-way delay error is identified on the basis of the first to eighth time points. In the sixth step, a compensation value of the two-way delay error is identified on the basis of the delta value.
