A novel node device enables transmission of a wideband signal, in compliance with various acceptable transmission standards and protocols. The signal consists of the legacy spectrum of about 5-860 MHz as well as a new downstream spectrum of about 1000-2000 MHz and a new upstream spectrum of about 2000-3000 MHz or about 930-1100 MHz. The novel device enables transfer of additional data in the upstream direction employing multiple upstream bands without making substantial investment in upstream physical node splitting thus providing networking services to residential subscribers, as well as to small and medium-sized businesses (SMB), which may operate under existing DOCSIS protocols and controlled by standard DOCSIS routers (CMTSs).

A system and method for spectral node splitting in cable TV network based on hybrid fiber-coax architecture is disclosed. Two-way optical signals carrying video and/or multimedia content are received at a signal distribution node. Portions of the received signals are processed according to the functionality the direction thereof. Certain frequency ranges are passed intact while specific different downstream and specific different upstream frequency bands are converted in a manner as to be allowed to be multiplexed into an extended broadband signal. The frequency bands within the extended broadband signal are distributed selectively among separate branches of the network. The frequency bands dedicated to the upstream traffic are received selectively from the separate network branches to be back converted and transmitted upstream to the network controller.
