Transmission quality measurement method for optical wavelength division multiplexed (WDM) network using symbols |
摘要 |
The measuring symbols are coded into the transmitted data. The symbol energy necessary for the symbol recognition is distributed among a wide period end by reducing the signal power of the data. The noise gap demanded for useful data transmission is observed both in optical power density and electrical power density spectrums of the base-band.
