| 摘要 |
An apparatus comprising a plurality of optical line terminals (OLTs) corresponding to different providers that share an optical distribution network (ODN), a plurality of optical network units (ONUs) coupled to the OLTs via the same ODN and configured to communicate with the different OLTs using different corresponding pairs of upstream and downstream channels, wherein the upstream and downstream channels are interleaved across a plurality of wavelength bands and comprise a sequence of alternating and contiguous upstream and downstream channels, are aligned with a plurality of wavelength division multiplexing (WDM) channels, and satisfy a plurality of design requirements for the OLTs and ONUs. |
