Coarse Wavelength Division Multiplexing for the Joint Transmission of 622Mbit/s- and CATV Signals in the Optical Network of a City Carrier

摘要

For an existing optical network of a city carrier running at a wavelength of 1.31μm so far investigations were performed to clearify the possibility for extending the transmission capacity. Beside the digital signal channel in use an additional CATV signal in coarse wavelength devision multiplexing (CWDM) technology was introduced at λ =1.55μm. The experimental results of a field trial are presented in this work.
