ABSTRACT:
The invention relates to a method for optimizing the optical power in an optical network that has a plurality of network nodes each having a transmitter and a receiver. The method comprising generating an optical signal at a first network node, receiving the optical signal at a second network node, detecting the optical power of the optical signal at the second network node, determining whether the optical power detected is outside a defined range, and in this case, generating, for the first network node, a control signal for increasing or decreasing the optical power, sending the control signal to the first network node, and increasing or decreasing the optical power of the optical signal emitted at the first network node. The invention further relates to an optical network having network nodes which are operable to implement this method.
