ABSTRACT:
Embodiments of the invention provide a method, device and/or system for communicating over a wideband distribution network. The device may include, for example, a downstream conversion module for converting a legacy downstream electrical signal of a legacy downstream frequency band into an extended downstream optical signal of an extended downstream frequency band; and/or an upstream conversion module for converting an extended upstream optical signal of an extended upstream frequency band into a legacy upstream electrical signal of a legacy upstream frequency band. Other embodiments are described and claimed.
