Claim:
1. A remote CMTS fiber node (CMRTS) system for a Hybrid Fiber Cable (HFC) network, the remote CMTS fiber node comprising: at least one optical to electrical converter for converting optically transmitted RF waveforms received from a first optical fiber medium to first set of downstream CATV RF waveforms; at least one software controllable radio frequency (RF) modulator device; at least one software controllable switch remotely configured to (i) select a set of digitally encoded optical signals received from a second optical fiber medium and (ii) direct the at least one software controllable RF modulator device to encode said selected set of digitally encoded optical signals into a second set of downstream CATV RF waveforms; wherein said at least one software controllable RF modulator device, and/or said software controllable switch comprise at least one software configurable field programmable gate array (FPGA) and at least one digital signal processor (DSP) configured to implement Media Access Control (MAC) and physical layer (PHY) operations; wherein said at least one software controllable switch and said RF modulator device are controlled by a remote virtual shelf manager system that comprises at least one virtual CCAP controller and at least one edge router.
