| 摘要 |
A device (D) is dedicated to controlling auxiliary paths (CP, SC) in a hybrid optical communications network comprising a multiplicity of hybrid nodes (NO) including switching means (CM1) and color converter means (CM2) and interconnected by transmission lines. The device comprises processor means (MT) adapted, in the event of a fault on at least one of the transmission lines carrying a connection and at the ends of which are two hybrid nodes (NO) adapted to effect switching in opaque mode, to command the switching means (CM1) of at least one of the hybrid nodes (NO) to switch the optical signals taking the connection to a selected auxiliary path independent of color and passing through said nodes, where applicable after color conversion of the optical signals by the associated converter means (CM2).
