Abstract: A system and an associated method of bidirectional optical transmission between a central terminal (101) and a plurality of client terminals (11, 12) via a passive optical network (PON) (3), wherein the conversion of an OTDM signal into a WDM signal (respectively the conversion of a WDM signal into an OTDM signal) is effected by an optical converter (20) (respectively 21) by a soliton trapping effect during a downlink (respectively uplink) transmission stage.

Abstract: A device and method are provided for transmitting an optical signal including at least two optical components to be transmitted respectively through at least two optical links that can be established respectively between the transmission device and at least two terminal devices. The transmission device and method associate, based on at least one parameter representative of the optical losses of the optical links, at least one of the optical components to at least one optical link selected from the optical links and to a transmission optical power.

Abstract: A method and apparatus are provided for processing a composite optical signal formed of a sequence of time sectors obtained by time-division multiplexing a plurality of optical signals transmitted on a plurality of transmission channels of a shared optical access network. The method includes: taking account of a schedule for transmission of the plurality of optical signals in the access network, the schedule associating with a time sector an optical signal of the sequence and a transmission channel of the plurality of transmission channels used by the optical signal; recovering a set of representative performance parameters of the transmission channel associated with the time sector; and adaptively correcting the time sector using the set of parameters.
