Abstract

The invention relates to a wavelength routed optical communication network in a hubbed configuration. The network comprises a hub node (H) and a number of satellite nodes (A, B, C...) connected to two optical fibre means (F1, F2) in an optical ring architecture. Each satellite node works in an individual wavelength channel. The satellite nodes (A, B, C...) are connected to the fibres (F1, F2) by passive multiplexers and demultiplexers (4' to 7') and all kinds of switching in the network is provided in the hub means (H).
