我们在这里的重点是IT设备和IT数据中心内的数据通信。光通信并不新鲜。因此，一个显而易见的问题很可能是：为什么会有一篇题为《为什么是光数据通信，为什么是现在？》的论文。原因有两个。首先，现在比以往任何时候都更需要光数据通信。即使认为在不太遥远的将来需要这样做也不过分。其次，光子学和光学这一广阔领域的进步使光通信几乎达到了最终可以跨越门槛、比电子信号更便宜的地步。在这篇文章中，我们阐述了为什么我们必须在数据中心内的所有长度范围内积极采用光纤进行数据通信。本文的总结是，光通信是不可避免的，我们给出了我们认为这是正确的理由。
Our focus here is on data communications within IT equipment and in IT data centers. Optical communications is not new. Thus the obvious question is likely; why a paper entitled, “Why optical data communications and why now?”. The reasons are twofold. First, optical data communications is more necessary now than it has ever been in the past. It is not excessive to even consider that it will be required in the not too distant future. Second, the advances in the broad field of photonics and optics have brought optical communications nearly to the point that it can finally cross over the threshold to be less expensive than electronic signaling. In this paper we make the case why we must aggressively pursue optics for data communications at all length scales within the data center. The summarization of this paper is that optical communications is inevitable, and we offer reasons why we believe this is true.
