论文摘要
红外（IR）上行链路可以达到高数据速率，这在一系列应用中至关重要。本文介绍了一种新型方法，以启用数据中心上行链路通信。我们介绍了一种新颖的方法，以实现架子和脊柱开关之间的通信。在我们提出的数据中心中，我们考虑三个架子，每个机架都有其自身的角度多样性发射器（ADT），位于机架顶部。四个广泛的视野接收器固定在数据中心的天花板上。每个这样的接收器都连接到脊柱开关。当每个链接以高于2.8 GB/s的数据速率运行时，我们评估我们提出的系统的性能。可以使用多个链接使用空间或波长维度来实现更高的数据速率。结果表明，我们所提出的系统能够在使用简单的启用钥匙的同时以良好的性能以高数据速率工作。
Infrared (IR) uplinks can achieve high data rates, which are essential in a range of applications. This paper introduces a novel approach to enable data centre uplink communication. We introduce a novel method to enable communication between racks and spine switches. In our proposed data centre, we consider three racks, each of which has its own angle diversity transmitter (ADT) that is located on top of the rack. Four wide field of view receivers are fixed to the ceiling of the data centre. Each such receiver is connected to a spine switch. We evaluate the performance of our proposed system when each link operates at a data rate above 2.8 Gb/s. Multiple links can be used to achieve higher data rates using the space or wavelength dimensions. The results show that our proposed system has the ability to work at a high data rate with good performance while using simple on-off-keying.
