The invention provides a regenerative interface (70, 80, 90, 100, 110, 120, 1500) for an optical communication system (10), the system (10) 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. The interfaces (70, 1500) are included in the system (10) where communication traffic propagating in the rings (20, 30, 40, 50, 60) transfers from one ring to another. Each interface (70) is capable of providing an all-optical waveband reconfigurable communication link between the rings (20, 30, 40, 50, 60). At each interface (70), conversion of optical radiation to corresponding electrical signals only is performed for regeneration when transferring communication traffic from one ring to another, otherwise the system (10) handles the communication traffic in the optical domain thereby providing a potentially larger communication bandwidth compared to conventional optical communication systems. Radiation diverted between rings may be regenerated.
