This paper introduces a radio-over-fiber (RoF) architecture for transmission of 60-GHz multi-gigabit millimeter wave (mmWave), emitted by two different sources, a vertical cavity surface emitting laser (VCSEL) and distributed feedback (DFB) laser connected with electro-absorption modulator (EAM) using wavelength-division multiplexing (WDM) technique. These light generation techniques are used for delivering in-building wireless personal area network (PAN). At centralized office (CO), data are modulated simultaneously over two light waves under one infrastructure that will provide a 60 GHz mmWave, which is a cost-effective and efficient system. Due to the use of dynamic integrated architecture, millimeter-wave radio-frequency (RF) component will reduce the cost at the central office. With the proposed system, acceptable bit error rate (BER) less than 10^–9 with a reasonably good carrier suppression of 40 dB is achieved after modulation, which facilitates lower power consumption architecture. Hence our proposed system using VCSEL and DFB can be best suited for indoor communication in a power-efficient and cost-effective manner. The susceptibility scale for investigation of these light-waves comes under 3 dB.

本文介绍了一种用于传输60 GHz数千兆毫米波（mmWave）的光纤无线电（RoF）架构，该架构由两个不同的源发出，垂直腔表面发射激光器（VCSEL）和分布式反馈（DFB）激光器使用波分复用（WDM）技术与电吸收调制器（EAM）连接。这些光生成技术用于交付建筑物内无线个人局域网（PAN）。在集中式办公室（CO）中，在一个基础架构下将通过两个光波同时调制数据，这将提供60 GHz毫米波，这是一种经济高效的系统。由于使用了动态集成架构，毫米波射频（RF）组件将降低中心局的成本。使用建议的系统，调制后可实现^–9的载波抑制为40 dB，具有良好的性能，这有助于降低功耗架构。因此，我们提出的使用VCSEL和DFB的系统可以以省电且经济高效的方式最适合室内通信。研究这些光波的敏感性等级低于3 dB。
