| 摘要 |
In accordance with the teachings of the present invention, a system and method for transmitting optical markers in a passive optical network (PON) system is provided. In a particular embodiment, a method for transmitting optical markers in a PON system includes transmitting a first optical marker signal, the first optical marker signal used to identify at least one of the first optical marker signal, an upstream wavelength corresponding to the first optical marker signal, and an optical network unit (ONU) type transmitting at the upstream wavelength corresponding to the first optical marker signal. The method also includes transmitting a second optical marker signal, the second optical marker signal used to identify at least one of the second optical marker signal, an upstream wavelength corresponding to the second optical marker signal, and an ONU type transmitting at the upstream wavelength corresponding to the second optical marker signal. The method further includes, at a distribution node of the PON, routing the first optical marker signal to a first set of one or more optical fibers in a PON each corresponding to a first upstream wavelength and routing the second optical marker signal to a second set of one or more optical fibers in the PON each corresponding to a second upstream wavelength.
