A system for communicating supervisory information between amplifier nodes in an optical communication network utilizes modulation of an included pump source to superimpose the supervisory information on data signals (typically customer data signals) propagating between the amplifier nodes transmitted customer signals. The modulated pump appears as a modulated envelope on the amplified data signal exiting the amplifier node, and may be recovered by suitable demodulation components located at the second node (i.e., the destined receiver of the supervisory information). The supervisory information may include monitoring messages, provisioning data, protocol updates, etc., and is utilized as an input to an included modulator, which then forms a drive signal for the pump controller.
An arrangement for transmitting protocol information to a plurality of N concatenated amplifier nodes of an optical communication system without using a dedicated channel, comprising
A system for supporting bi-directional communication of supervisory messages between a first amplifier node and a second amplifier node in an optical communication network, each amplifier node including a section of rare earth-doped optical fiber and a pump source for injecting a pump beam at a predefined wavelength into the section of rare earth-doped optical fiber and imparting gain onto a data signal propagating therethrough, the system comprising
