Upstream Scheduling in a Passive Optical Network |
| 摘要 |
In general, the 1G-EPON standard specifies its upstream waveband broadly to allow for low cost lasers to be used to transmit upstream. Often, however, the lasers actually used by many 1G-ONUs to transmit upstream only occupy a narrow waveband that does not overlap with the upstream waveband specified by the 10G-EPON standard. The present disclosure is directed to systems and methods that exploit this fact to efficiently provide for the coexistence of 10G-EPON and 1G-EPON over the same set of optical fibers in the upstream direction. |

1. A method comprising:
measuring an amount of power received from a first optical network unit (ONU) in a waveband used by a second ONU to transmit upstream over a passive optical network (PON); and based on the detected amount of power received from the first ONU in the waveband, scheduling the first ONU to transmit upstream over the PON with the second ONU in a pure time-division multiple access manner or in a combined time-division and wavelength-division multiple access manner. |
