    A modulated pseudo-Hermitian optical dimer is investigated. The parameter ranges are determined where the eigenmodes of the dimer conserve their power. It is shown that such a dimer has several exceptional points, and it is found that the dimer modes can conserve their average power over the period even if each of its segments is in the PT-broken phase. On the other hand, even if each segment is in the PT symmetric phase, the average power over the period is not conserved for the dimer. Thisspecial feature is determined by the relationship between the dimer length and the beat period of the signal in the individual segments of the dimer.
