基于FSO技术的“最后1km”宽带接入

Broadband connectivity for last mile by FSO technology

自由空间光 (FSO)技术作为地下光纤网的补充 ,在提供“最后 1km”宽带接入方面与其他的固定无线设备相比有很强的竞争力。虽然通过空气传输光信号仍然存在技术上的挑战 ,但是与敷设光纤网相比 ,FSO成本低、安装快捷 ;与安装其他固定无线网络相比 ,FSO还具有高速宽带和无需许可的特点 ,具有非常好的应用前景。

Free-space optics (FSO) technologies are being used to complement fiber in metro optical networks, compete with fixed wireless equipment in providing broadband last-mile access.While there are technical challenges to transmitting optical signals through the air, FSO offers a number of very attractive features - most notably the low cost and rapid deployment speed relative to deploying fiber optic networks, plus the high bandwidth and unlicensed nature of FSO relative to deploying fixed wireless networks.
