Error tolerance analysis of the Telefónica de España optical fibre network

Complex systems and networks are growing in importance from a scientific point of view. We analyzed the Telefónica de España optical fibre network in order to find out whether it behaves as a complex network, so that this model can be used to identify weak points in the network to prevent service disruption. We found out that the optical fibre network shows some scale-free network properties, but also has its practical limits and geographical constraints, and therefore applying the scale-free model to this network can be done but its peculiarities must be taken into consideration.
