Abstract

Intense interest has been generated by the possibility of transmitting multiple AM-VSB NTSC signals over optical fiber. However, noise and distortion levels have not been consistent with objectives for signal quality in the CATV trunking application.¹ In addition, lasers have usually been selected from a population intended for digital applications. Here we report on experiments using 1.3-μm DFB laser modules where rigorous requirements for signal quality have been satisfied. In addition, we discuss data from >100 devices which were specifically processed for analog applications.
