Design Of Efficient Optical Fiber Systems For CATV/HDTV Distributions

Abstract

We present the design of intensity-modulation directdetection optical fiber communication systems with erbium-doped fiber amplifiers for CATV/HDTV distributions. Three system configurations: the In-Line Amplifier scheme; the Passive Star Coupler with Optically Preamplified Receivers scheme; and the Hybrid Passive-and-Active Star Coupler scheme; are considered. The receiver sensitivity is calculated for various system parameters. We also compare these three schemes through the number of HDTV subscribers.
