Summary

As cable television (TV) networks migrate to deep fibre or fibre to the home (FTTH) architecture, it is now easier to provide bidirectional high-quality media services that require very high-speed digital transmission of various high-quality contents. As cable TV networks provide services by transmitting radio frequency (RF) signals between headend and a cable modem (CM), the configuration and devices of the cable TV network are optimized for RF signal transmission. For migration to all-fibre access, the existing cable TV network devices of service operators (SOs), which provide broadcasting services and various data services through a TV network based on hybrid fibre coaxial (HFC) cable, are recommended for change to new network devices. Therefore, a cost-effective solution for deployable and acceptable migration towards optic-based cable TV networks is required. Recommendation ITU‑T J.1106 provides a cost-effective solution to convert HFC-based cable TV network devices into those based on optic cable.
