Treatment methods and devices for determining the PMD-induced outage probability of an optical transmission system

摘要

The present invention relates to a treatment method for determining the probability of a PMD-induced disorders of the optical transmission system in particular. For this purpose, and the present invention, (10,11,12,13a, 13b, 14,15,20), (10,11,12,13a, 13b, 14 the optical transmission line at least one position of the transmission line , by applying the target expression intermediary to the second position in the at least one location downstream from the position of the first 15,20), the light in (T _total) of a / specifiable observation time specified optical signal transmitted by the optical transmission system and / or the polarization state of the transmission system has been modified or is measured quantitatively (BER) for / specifiable signal characteristic specification specified / Not specifiable period in which the signal characteristics is the probability of the PMD-induced failure of the optical transmission system and has been checked whether or not to conform to the (BER _th) threshold conditions, has been measured can not be satisfied (BER _th) threshold condition I advocate the processing methods, such as has been calculated based on the ratio of the length of observation time (T _total) and the length of the portion of the time is of (T _out).
