Abstract :
A remote node design with a wavelength tuneable optical add/drop element is presented and experimentally demonstrated for application in a resilient ring+tree access network architecture. The flexibility of the network node regarding its allocation to the wavelength dimension of the network can be exploited to retain service delivery in case of subsystem failure at the optical line terminal (OLT) or optical network unit (ONU) as well as for an optimization of the transmission performance when switching from normal to resilient network operation in case of a ring fibre cut. A loss budget of 30 dB is compatible for the passive optical access network.
