ABSTRACT:
A system for management of bandwidth, cost control, and operational efficiency in a fiber optic, ethernet-based, TDMA communications system. The invention features an aggregating optical node between a central office and end users. The optical spectrum is divided according to end user, direction (i.e., upstream or downstream), and/or according to function (e.g., video or non-video). In an embodiment of the invention, a wavelength coupler can be used to couple multiple upstream wavelengths from respective end-user devices, for forwarding to a central office. Moreover, adaptive equalization can be used for noise cancellation purposes.
