Abstract

Subcarrier modulation has become an attractive technique for the transmission of digital,¹ FM,^2,3 and more recently amplitude-modulated (AM) vestigial-sideband (VSB) video information.⁴ Although the technology for FM or digital systems has long been in place, the popularity of such systems is limited by the incompatibility of the transmitted format with AM-VSB compatible consumer electronics and the CATV network. Multichannel AM-VSB systems provide a means to establish fiber in the CATV network with no format conversion. In exchange for this compatibility, one must overcome problems with nonlinearity and noise and contend with a limited transmission loss budget.
