SCTE Technical Journal December 2021: Extended Upstream – a Pragmatic Approach
The cable industry relies on Data Over Cable Service Interface Specification (DOCSIS) 4.0 technology to serve the needs of future applications requiring multi-gigabit symmetric services over Hybrid Fiber-Coax (HFC) networks. The capacity increase of downstream due to extended frequencies has been studied both in theory and practice. However, the increase of upstream capacity on the grounds of higher split frequencies has been analyzed theoretically, but practical considerations are conspicuously absent. The cable industry is keenly aware of the importance of ultrahigh upstream speeds due to the competitive offers from fiber to the home (FTTH) providers, motivating cable to invest in next generation DOCSIS.
