Abstract:
1. A system for transporting a plurality of digital signals which comprises: a head-end unit for respectively routing each digital signal to a particular modem according to address information in the digital signal, wherein all digital signals are initially carried on a substantially same radio frequency (f an optical fiber having a first end and a second end; a first converter connected to the first end of the central optical fiber for stacking the plurality of digital signals, with their respectively unique radio frequency, onto a common wavelength (λ) for transmission as an optical signal over the optical fiber; a second converter connected to the second end of the central optical fiber for de-stacking the plurality of digital signals and segregating each digital signal according to its respective unique radio frequency; and a distribution unit for directing each unique radio frequency signal to an addressed node, wherein further transmission from the node is over a secondary network dedicated to the node.
