摘要

本文介绍了一种通过光纤双向发送一对宽带调频信号的双向传输系统。采用1.3 /spl mu/m的LED传输系统的带宽约为300 MHz,载波噪声比(CNR)为16 dB。即使光功率损耗很大,也可以连接1公里长的光纤进行双向通信。

Two-way optical fiber wideband FM signal transmission using LEDs
This paper describes a two-way transmission system for sending a pair of wideband FM signals in both directions via an optical fiber. The transmission system using an LED at 1.3 /spl mu/m has a bandwidth of approximately 300 MHz with a carrier-to-noise ratio (CNR) of 16 dB. The optical fiber of 1 km long can be connected for two-way communications even though the optical power loss is great.<>
