1. A method for ensuring eye safety in an optical network, the method comprising:

  • detecting optical connectivity between an output of a transmit amplifier and a passive optical processing element, the transmit amplifier being located at a first network node and being configured to output optical power greater than a given level, and the passive optical processing element being located at a second network node and being configured to guarantee a reduction of a maximum optical power level at an output side of the passive optical processing element to the given level, and wherein the detecting occurs at the first network node and includes transmitting a signal from the first network node at which the transmit amplifier is located and receiving the signal at the first network node; and

    enabling or disabling the transmit amplifier as a function of detection of the optical connectivity.
