Description
Summary:Current CATV broadband networks are described, and a simplified model of these AM systems is given. AM systems performance metrics are examined from a CATV perspective. Noise sources are summarized, and the effects of intermodulation noise and laser nonlinearity are discussed. It is shown that the rigorous signal quality objectives associated with the CATV trunking application can, in principle, be satisfied with lightwave technology. The successful transmission of 42 carriers over 12 km of fibre while maintaining a C/N of 52 dB and composite distortions of less than -70 dBc is reported.< >
