Abstract :
Dense-wavelength-division-multiplexed (DWDM) technology has emerged as a viable option for the cable-TV operators to solve their current HFC network architecture design. Performance requirements to increase upstream traffic capacity using time-division-multiplexing (TDM) and frequency stacking methods with directly or externally modulated DFB laser transmitters will be presented. In addition, the advanced upstream physical layer standard for cable modems consisting of frequency-agile TDMA and synchronous code-division multiple-access (S-CDMA) methods will be reviewed.
