采用超越光纤系统给常规同轴电缆分配设备馈送节目近来备受青睐。因调幅光纤系统采用业已存在于当今同轴系统中的残留边带调幅(VSB/AM)视频信号,故它可提供许多超过其它传送方式的优点。本文将谈及这种类型的光纤系统。文中尤其将探讨呈现出载噪比和失真性能符合当今要求的调幅光纤系统的关键部件。
The use of transceivers over fiber systems to distribute equipment for conventional coaxial cable distribution programs has recently gained much traction. Because AM uses a VSB / AM video signal that is already present in today’s coaxial systems, it offers many advantages over other modes of delivery. This article will talk about this type of fiber optic system. In particular, the paper will explore key components that exhibit an AM fiber system that meets today’s requirements with carrier-to-noise ratio and distortion performance.
