Abstract:
1. A method for operating a fiber optic network, comprising: receiving, with a particular network node, an optical signal from a star coupler, the star coupler receiving an output from each of a number of network nodes coupled to the star coupler; adjusting an optical transmission power level for a particular network node to be substantially equal to an average transmission power level for the output of the number of network nodes coupled to the star coupler; diagnosing an other network node as being absent from the fiber optic network when a number of channels associated with the other network node are indicated by a substantially zero power level in the optical signal received from the star coupler; and adjusting optical amplification of the optical signal received from the star coupler such that a number of channels included in the optical signal are within an operating range for a number of receivers associated with the particular network node.
