In this paper we evaluate quantitatively the effect of the optimum equalization in comparison with the full cosine roll off (F.C.R.O.) and with Gaussian equalization in optical fiber digital transmission systems. As a result, the optimum equalization makes the repeater spacing longer by about 0.4dB (at 10Mbits/s) than the F.C.R.O equalization in the case of the optical fiber having fairly wide bandwidth. Moreover, the effect of improvement of the repeater spacing by the optimum equalization brings us about 2dB of improvement in the case of the optical fiber having narrower bandwidth than signals.
