Abstract
A system for delivering multiple passive optical network services is disclosed. The system includes a first optical transmission service comprising a common wavelength pair routed from a source to each of a plurality of subscribers. The system further includes a second optical transmission service comprising a plurality of unique wavelength pairs, where each of the unique wavelength pairs is routed from the source to a subscriber among the plurality of subscribers. The system delivers the first optical transmission service and the second optical transmission service to the subscriber on a single optical fiber.

A system for delivering multiple passive optical network services comprising:
- a first optical transmission service comprising a common wavelength pair including a common upstream wavelength and a common downstream wavelength routed from a source to each of a plurality of subscribers;
- a second optical transmission service comprising a plurality of unique wavelength pairs including a unique upstream wavelength and a unique downstream wavelength, each of the unique wavelength pairs routed from the source to a subscriber among the plurality of subscribers without the unique downstream wavelength being routed to another subscriber among the plurality of subscribers;
- a wavelength division multiplexer configured to separate each of the unique wavelength pairs of the second optical transmission service onto separate optical fibers;
- and
- a splitter joining a fiber carrying the common wavelength pair with one of the fibers leading from the wavelength division multiplexer carrying one of the unique wavelength pairs to transmit the common wavelength pair and the unique wavelength pair to the subscriber on a single optical fiber, such that the first optical transmission service and the second optical transmission service are delivered to the subscriber on a single optical fiber.
A method of delivering multiple passive optical network services, the method comprising:
- splitting a first optical transmission service from a source to a plurality of subscribers, the first optical transmission service including a common wavelength pair including first and second wavelengths;
- separating, via a wavelength division multiplexer, a second optical transmission service including a plurality of unique wavelength pairs onto a corresponding plurality of optical fibers, each optical fiber receiving a unique wavelength pair including unique first and second wavelengths associated with a subscriber among the plurality of subscribers without the unique first and second wavelengths being routed to another subscriber among the plurality of subscribers;
- and
- routing the first and second wavelengths of the first optical transmission service and the first and second wavelengths of the second optical transmission service to a splitter, the splitter configured to combine the first optical transmission service with the unique wavelength pair of the second optical transmission services to the subscriber on a single optical fiber.
