ABSTRACT:
Data transmissions from each of a multiplicity of users in a fiber-optic communications network employ pulse stream frequencies which uniquely differ by a given period offset, .DELTA.t, and are thus characteristic of each particular user. Such pulse streams 11, 12, etc. are multiplexed for transmission through the network, yet may be individually extracted at the facilities of a receiving user by means of a selector 26 comprising one or more non-linear optical logic devices 35, such as bistable semiconductor laser amplifiers or self-electrooptic effect devices, which are associated with optical delay means 34 having period offset characteristics peculiar to that of a specific transmitting user.
