　　观察半导体激光技术的先进性让人印象深刻。年长的边缘发射激光二极管都让位给了垂直腔面发射激光器（VCSEL）。这导致了更低的成本和更高的可靠性，因为VCSELs不需要模具的90度的重新定位一样的边缘发射技术。

　　VCSEL，再加上减少半导体的几何形状，使光纤世界大幅增加其高速发射器和接收器的组合。10克、25克、40克，现在的100 Gbit / s的单模光纤链路模块，支持热插拔，低功耗，标准形式的因素是革命性的设计和架构的数据中心和通信枢纽。

　　At the same time large facilities like hospitals， universities， government buildings， TV/radio buildings， and more are requiring higher amounts of data traffic at higher speeds by more users. In addition， the term “users” includes people and—in this age of IoT—other other web- and cloud-enabled devices.

　　This article looks at ways in which RF data and signals can be sent through fiber-optic media. It will examine the advantages and disadvantages of this approach， as well as methods in which these implementations can address the need for higher speed and flatten out network topology.
