Abstract :
Design considerations for subscriber multiplexed (SCM) systems distributing multichannel analog/digital signals are reviewed. In particular, video distribution schemes based on lightwave transmission technologies are discussed. The two most important system design considerations in an SCM system are the control of intensity noise and nonlinear distortions. Intensity noise characteristics and degradation caused by optical reflections are discussed. Laser and detector linearity requirements are reviewed. System signal-to-noise ratio analysis is performed. Design considerations for receivers for SCM systems are reviewed, and various system applications are examined
