摘要： Particular embodiments provide a method for delivering data in the upstream direction without the need for upstream radio frequency (RF) modulation. For example, in some embodiments, an optical network may reach to a gateway associated with a user device. The gateway may receive digital baseband data from the user device in the upstream direction. The gateway can then send the digital baseband data through the optical network without modulating the digital baseband signal via radio frequency. At the headend, because no modulation is performed in the upstream direction, there is no need for de-modulation in the headend. In one embodiment, a scheduler-based approach is used to avoid instances of optical beat interference in the upstream direction as only one upstream device that may interfere with other devices may be able to send data at one time.
摘要翻译：具体实施例提供了一种用于在上行方向传送数据而不需要上行射频（RF）调制的方法。例如，在一些实施例中，光网络可以到达与用户设备相关联的网关。网关可以在上游方向从用户设备接收数字基带数据。然后，网关可以通过光网络发送数字基带数据，而无需通过射频调制数字基带信号。在前端，因为在上游方向上没有进行调制，所以不需要在前端进行去调制。在一个实施例中，使用基于调度器的方法来避免在上游方向上的光学差拍干扰的实例，因为只有一个可能与其他设备干扰的上游设备可能能够一次发送数据。

摘要： An active receiver structure that combines a large number of detectors without bandwidth penalty may provide a better signal-to-noise ratio (SNR) than conventional Radio Frequency over Glass (RFoG) networks. A transmission line receiver is used to combine a large number of optical detectors into a single radio frequency (RF) signal without a bandwidth penalty and a modest penalty in noise performance that results in an SNR that is much better than traditional optical combining techniques that are followed by a single detector. An optical multiplexer structure may be designed around the active splitter such that passive optical network (PON) operation is not impeded.
