摘要： A multimode combiner or coupler (MMC) may combine the inputs into a larger core multimode fiber. The multimode combiner may be combined with a re-transmitting laser for detecting and re-transmitting signals. Thus, the multi-mode combiner may detect and combine input signals, and then retransmit the detected, combined signal. The detection can be implemented with multiple single mode fibers to small single mode detectors or a multi-mode coupler with a larger multi-mode detectors. In embodiments of the MMC, a bi-directional optical splitter/combiner includes a transmitter for re-transmitting an RF signal received at a receiver, a first wave division multiplexer (WDM) combiner combining the output of the first transmitter in an upstream direction to a downstream signal in a downstream direction, and a second WDM combiner combining split downstream signals in the downstream direction with upstream signals received via at least two optical fiber inputs.

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。
