摘要

本文提出了一种基于掺铒光纤放大器的强度调制直接探测光纤通信系统的设计,用于有线电视/高清电视分布。三种系统配置:在线放大器方案;无源星耦合器与光预放大接收机方案;无源-有源混合星形耦合器方案;被认为是。计算了不同系统参数下的接收机灵敏度。我们还通过高清电视用户数量对这三种方案进行了比较。

Design Of Efficient Optical Fiber Systems For CATV/HDTV Distributions
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.
