Optical filter type influence on transparent WDM network’s size
The number of nodes (size) of an optical transparent network-island is limited according to Bit Error Rate (BER) estimation of the optical signals that cross transparently the optical nodes. Three optical add-drop multiplexer – based on different filter technology and therefore different architecture – is cascaded and compared by BER-degradation estimation in a special network architecture environment.
