In this paper, we propose a scheme to produce multiplexed entanglement frequency comb in a typeⅡphase matching nondegenerate optical parametric amplifier (NOPA) operating below threshold. The entanglement of the signal and idler frequency combs in the wide frequency range, which is limited by the phase matching bandwidth of the NOPA, is investigated by the inseparability criterion. Furthermore, N Einstein-Podolsky-Rosen (EPR) pairs can be created from the two combs without any reduction in the c
