Abstract
In order to utilize the 1GHz bandwidth made available with cable systems based on fiber-trunk/coax-distribution architecture, we have built and evaluated the first broadband AM-VSB/64QAM hybrid lightwave CATV system which can provide 60 conventional AM-VSB channels (55.25MHz – 439.25MHz) and ten 64QAM (90Mb/s/ch) channels (525MHz – 750MHz) using a single DFB laser. This system is compatible with current cable networks and promises delivery of new digital services using video compression and spectrally efficient multi-level RF techniques. The channel capacity can be increased greatly with little increase in laser’s overall RF load, making one-laser/one-fiber broadband transmission feasible and attractive[1,2].
