经过近几年突飞猛进式的发展,有线电视网络在全国城乡各个角落编织起来,奇迹般地成为全国最大的弱电网络。如何改善网络质量、提高网络层次,充分扩展网络功能,是摆在网络营运者面前的一个重大问题。如果说光纤技术的成熟,为我们解决这一问题提供了一个强有力的技术手段,则“信息高速公路”的提出,为有线电视发展提供了一个难得的契机。基于光纤电缆混合网(HFC)结构的有线电视
After rapid development in recent years, the cable television network weaves in every corner of the country’s urban and rural areas and miraculously becomes the largest weak network in the country. How to improve the network quality, improve the network level and fully expand the network function is a major issue facing network operators. If the maturity of optical fiber technology provides a powerful technical measure for us to solve this problem, the proposal of “Information Superhighway” will provide a rare opportunity for the development of CATV. Cable television based on fiber optic cable hybrid network (HFC) architecture
