摘要

本文对支持移动宽带爆炸式增长的光纤无线通信技术进行了综述。RoF系统将为分布式天线系统(DAS)提供一个平台，作为长期演进(LTE)技术的前传。为了支持大型DAS拓扑结构，需要从宏单元中获得更高的分裂比，因此更高的光发射功率(OLP)是正确的方法。然而，高OLP会产生不希望的非线性，即受激布里渊散射(SBS)。本文涵盖了解决SBS流程的三个不同方面，其中解决方案最终提供了额外的4 dB链路预算。

Solution to reduce nonlinearity in LTE RoF system for an efficient DAS topology: A brief review (Invited)

In this paper, a review on radio-over-fiber (RoF) technology is conducted to support the exploding growth of mobile broadband. An RoF system will provide a platform for distributed antenna system (DAS) as a fronthaul of long term evolution (LTE) technology. A higher splitting ratio from a macrocell is required to support large DAS topology, hence higher optical launch power (OLP) is the right approach. However, high OLP generates undesired nonlinearities, namely the stimulated Brillouin scattering (SBS). Three different aspects of solving the SBS process are covered in this paper, where the solutions ultimately provided an additional 4 dB link budget.
