Abstract:
1. A method for determining a maximum transmission distance for an optical link comprising heterogeneous types of optical fibre segments, the method comprising: retrieving, from a database, a maximum transmission reach value for each type of optical fibre present in said optical link; computing, along said optical link, a length of said optical fibre of each type to reach a distance, wherein, for each type of said optical fibre present in said optical link, segments are summed from a starting point to said distance to determine said length of each type of said optical fibre along said optical link; and normalizing said length for each type of said optical fibre in said optical link by multiplying said length of each type of said optical fibre by a weight chosen as a function of said maximum transmission reach value for each type of said optical fibre; summing said normalized lengths for a plurality of types of optical fibre; and determining said maximum transmission distance of said optical link as said distance for which said sum equals a given threshold.
