ABSTRACT:
A system for locating optical network elements and determining span loss in a network is described. The geographical locations of the first and second network elements in the network are determined with respect to an earth-based coordinate system. A network management system program displays iconic representations of the first and second network elements relative to one another with respect to the coordinate system. The distance between the first and second network elements over a network span linking the two network elements is determined. The transmission loss of the span is determined by multiplying the calculated distance by a transmission loss factor associated with the transmission medium coupling the first and second network elements. The component losses associated with each of the first and second network elements is determined using known specifications or direct measurement. The span loss is determined by adding the component losses with the transmission loss of the medium.
