PON wavelength bonding for providing higher-rate data services

Abstract:

Methods, systems, and apparatus for Passive Optical Network (PON) wavelength bonding are disclosed. In one aspect, a first frame of data to a first optical network unit (ONU) is transmitted by an optical line terminal (OLT) over a first wavelength. While the first frame of data is being transmitted to the first ONU over the first wavelength, a first portion of a second frame of data to a second ONU is transmitted by the OLT over a second wavelength. After transmission of the first frame of data over the first wavelength has completed and while the first portion of the second frame of data is still being transmitted to the second ONU over the second wavelength, a second portion of the second frame of data to the second ONU is transmitted by the OLT over the first wavelength.
