An OPU frame generating device includes a frequency setting unit that sets a frequency corresponding to a bit rate of data which can be stored in a payload area, a parameter calculating unit that calculates a parameter Cm
indicating an integer part of the amount of data included in the payload area using the set frequency, a data inserting unit that outputs a timing signal determined by the parameter Cm
and inserts data at a position determined by the parameter Cm
in the payload area, a data generating unit that generates data in synchronization with the timing signal, and a frame generating unit that generates an OPU frame having the payload area into which the data is inserted.
