What are the constraints and disadvantages of using cable modem technologies?
• Cable modem service is shared among multiple users, which can have an impact on the speed of the broadband connection depending on the number of people that are using the service at the same time. • Cable service has not been as universally deployed as telephone service, so it is a technology that is often not available in many areas. • Cable modem services are provided on hybrid fibre-coaxial (HFC) systems. Given that the cost of constructing a HFC system is similar to that of an all fibre system, it makes more sense to build an FTTH system. Cable Modem Technology and Local Open Access Networks The development of cable systems in other countries tended to occur later than North America and for the most part have never reached the level of penetration that exists in North America, particularly with the emergence of competing technologies, such as satellite. It is unlikely that with the convergence of technology, HFC systems will develop as standalone networks in countries that curren
