Cj. Chae et Rs. Tucker, Virtual optical self-healing ring network over star-configured optical cable plant using N x N arrayed waveguide grating, ELECTR LETT, 37(20), 2001, pp. 1241-1243
A method to implement optical self-healing ring networks in metropolitan an
d access areas where fibres have already been deployed in star shape is pro
posed. An experimental network operating at 2.5 Gbit/s is demonstrated.
