Compared with time division multiplex systems the coherent approach promises high flexibility and reliability improvements. A star topology of the local network of the universal network is assumed.enoptical fibresoptical linkssubscriber loopsoptical fibre communicationcoherent systemssubscriber loopoptical coherent multichannel techniquesuniversal public networksflexibilityreliabilitystar topology621Application of coherent systems in the subscriber loopconference paper
