Impact Of The Fiber Type Arrangement On Bidirectional Mixed-Fiber Optical Links

In this paper we investigate the impact of the fiber types arrangement on the performance of bidirectional mixed-fiber optical links. It is shown how to compose an optical link given a set of different fiber types in order to optimize the transmission bit error rate (BER). To this aim, a nonlinear interference noise (NLIN) theoretical prediction model was adapted to take into account different fiber types and their positions in the optical link. The analysis was performed considering a coherent wavelength- division multiplexing (WDM) transmission system with no inline dispersion compensation.
