摘要：

Broadcast digital video with QPSK modulation has been delivered over WDM passive optical networks by using spectral slicing of broad-band sources such as LED's, We compare a model for, and experimental measurements of, dispersion induced impairments in QPSK video transmission systems with broadband optical carriers, The model is a universal function of RF frequencies, PON fiber length, and source spectral width for any given spectral shape, and describes the functional form and major portion of the observed impairments, The system implications of spectral filtering for unamplified systems are also discussed.
