DOCSIS was crucial for the CATV sector since it contributed to industry standardisation.
A widely accepted telecommunications standard called DOCSIS (Data Across Cable Service Interface Specifications) permits high-bandwidth data transfer over pre-existing coaxial cable networks that were initially intended to transmit cable television programme signals (CATVS). The standard is currently in its third generation, and the market outlook is still favourable.
Cable networks started to lose ground over time as high-speed fiber-optic internet became more prevalent. But despite its strength, the well-established but much older technology survived the danger of competition. Coaxial cable technology needs the DOCSIS standard as a stepping stone in order to stay competitive and provide ever-faster Internet access without having to overcome Herculean challenges (and extremely costly)
