Optical networks are becoming lesser and more complex to design. The method of defeating these barriers is to use network simulators for expanding an optical network. This research focuses on determining if an optical network simulator is the best tool for network design. The simulators are differentiated by their features to provide an environment in a network, they are as follows: name of simulator, optical network element, language, easy to deploy, open flow switch, free or paid. These criteria are selected objectively and subjectively in the comparison. Using these parameters, the best simulator is found. The following evaluated optical network simulators are well-known tools: (1) OMNet++, (2) OPNET, (3) Optiwave, (4) Opti System, (5) Mininet, (6) CNET, (7) Cooja simulator, (8) NS3, (9) NetSim, (10) MATLAB.
