The invention provides a transponder interface (1400,) for an optical communication system comprising a plurality of mutually interconnected bi-directional optical waveguide rings (20, 30, 40, 50, 60) in which radiation modulated with communication traffic propagates. The radiation is partitioned into 32 distinct wavebands. Interfaces (70, 80, 90, 100, 110, 120, 1200, 1400, 1500) are included in the system where communication traffic propagating in the rings transfers from one ring to another. Each interface (70, 1400, 1500) is capable of providing an all-optical waveband reconfigurable communication link between the rings (20, 30, 40, 50, 60). At each interface (70, 1400, 1500), conversion of optical radiation to corresponding electrical signals is not required when transferring communication traffic from one ring to another and from waveband to another, thereby providing the system with a potentially larger communication bandwidth compared to conventional optical communication systems. Radiation passing through the interface (1400) may have its wavelength changed in transponder (1410).
