As fiber proves its worth in a variety of cable TV system architectures, system engineers can make greater use of fiber-optic wavelength division multiplexers, splitters or couplers, and directional coupler taps to reduce costs and provide for increased system utilization and expansion in the future.
This paper will focus on the basics of coupler technology with specific explanations of the functional parameters that need to be specified when purchasing these components. The presentation also will discuss the reasons for this emerging trend, specifically geared to the needs and interests of cable television operators.
