CATV Potential Of Externally Modulated Lasers (1992)
By Larry C. Brown, Magnavox CATV Systems, Inc.
In the last few years, DFB lasers have gained widespread use in CATV as the foundation for AM optical transmitter design. More recently, an important new generation of transmitters has emerged. These devices offer much higher optical launch power and spectral purity than is possible from a DFB design. This paper compares these externally modulated transmitters with their DFB predecessors, and explores potential benefits of the technology to CATV.
