    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).

    摘要: The emission frequencies (F(1) . . . F(2P)) used for simultaneous communications form a stack extending from a fixed based frequency (F(0)) to a top of stack frequency (F(2P-1), F(2-P)). At the beginning of each call, the emission frequency (F(2P-1)) used for the call is at the top of the stack. During the call, said emission frequency is maintained by being servo-controlled to a predetermined spectrum distance (DF) beyond a lower support frequency (F(2P-2)) providing such a frequency can be detected. When such a frequency cannot be detected, the emission frequency is shifted progressively towards the base frequency. The invention is particularly applicable to communications between the peripherals of computer systems.

    摘要: A method for routing traffic in a network comprising a plurality of nodes and a plurality of data lines that extend between adjacent ones of said nodes, the traffic being formed of traffic connections between pairs of nodes referred to as terminal nodes, comprises the steps of a) selecting a pair of said terminal nodes and determining a shortest path between them (S1-S4); b) selecting (S6) a new node from said plurality which is not part of the path and inserting (S8) the new node between two adjacent nodes of the path; c) repeating step b) until at least all terminal nodes are included in the path; d) routing at least part of said traffic on said path (S11-S14).

    摘要: In a long-haul optical communication line the fibers to be made into the line are grouped into pairs such that the two fibers in each pair have substantially symmetrical chromatic dispersion relative to a mean value of the chromatic dispersion of all the fibers of the line. These two fibers are thereafter connected consecutively into the line. The invention finds an application in telecommunications.
