We present a CAD realization for the physical layer of photonic networks based on a programming environment for complex development and simulation tasks. Verification of the numerical methods by fiber loop measurements shows that modeling has to be done in close connection with measurements of the relevant parameters of the separate network components. Simulation results of network-limiting effects (e.g., transmitter chirp, fiber dispersion and nonlinearity, amplifier noise) are presented in comparison with experimental measurements.
