Broadcast and television two-way network transformation and solution

In 2010, the national government determined the triple integration strategy development decision of telecommunications network, the broadcast and television network and the Internet, which is the inevitable choice for the country to achieve the industrialization of information. One of the key tasks of promoting the triple integration is to strengthen the network construction and transformation: to comprehensively promote the transformation of the digitization and two-way upgrade of the cable TV network and improve the service capacity and support capacity. Broadcast and television access network plays an important role in the whole network. It is the key and difficult point of the construction of broadcast and television network. Therefore, the primary task for broadcast and television to carry out a variety of interactive business in the future is to build “road” and transform access network bilaterally.


At present, there are four main programs of two-way transformation of radio and television to promote access network:
PON+EOC: to achieve the broadcast, interaction, voice, data and other business integration through the coaxial home.
PON+ small C: to achieve the broadcast, interaction, voice, data and other business integration through the coaxial home.
Coaxial + fiber: to achieve the broadcast, interaction, voice, data and other business integration through the coaxial cable and fiber optic cable into the home.
Double fibers and triple waves FTTH scheme: the integration of broadcast, interaction, voice, data and other business through the dual fiber optical fiber.
Single fiber and three waves FTTH scheme: the integration of broadcast, interaction, voice, data and other multi service integration by single fiber to the home.
