Optical spectrum and eye diagram at the output of an optical fiber network are very important terms for an optimized optical network designing process. So before designing, simulation is required which will give the idea about these terms. This paper describes an approach to simulate the different optical networks (WDM, OADM, ROADM and OFDM). Here the simulations are performed at two scales: frequency and time. The parameters used are optical spectrum (THz), electrical spectrum (GHz) & eye diagram (ns). The eye diagram gives the idea of Q-factor, BER, jitter, eye opening, eye closing and average eye opening.
