Details introduction
At present, the number of Chinese cable television network users has reached more than 100, mainly in the form of a one-way network. Main topics: (broadband, digital TV, video on demand, such as), has become a two-way Tv network and television operators in the current transformation in order to reduce maintenance costs and cope with increasing competition, how to make full use of the existing HFC network infrastructure to expand the two-way transmission services .
EPON-multipoint network structure is very similar to Tv network and television networks, while EPON natural mechanism makes it ideal for carrying broadcast video services. GWD proposed EPON + EOC two-way transformation solutions for Tv network and television networks.
EPON + EoC solutions in the metro section rooms and optical distribution network and EPON + LAN exactly the same way. ONU Ethernet CATV output within the corridor and through the corridor EOC mixing equipment, or ONU and EOC equipment placed in a node at the fiber to the corridor after corridor connected to each through the splitter, and then transmitted to each user on the original cable home, then divided into Ethernet and CATV signals through EOC CPE, providing customers with television and data services. EOC EOC equipment use baseband transmission, no power and easy maintenance.
Program features:
◆ Significantly reduce construction and maintenance costs - full use of existing cable, without re-laying Ethernet cables, reducing the initial investment is very inconvenient rewiring for cell-way transformation.
◆ Huge bandwidth capacity 1G EPON have the bandwidth capability of two-way, and can be upgraded to 10G, sufficient to ensure that users of business development needs for bandwidth.
◆ Mature Ethernet technology to reduce the cost to deploy and maintain, in line with future technology trends, protective equipment investment.
◆ Simple network level, end to end service configuration and management and maintenance, reducing maintenance costs.
◆ System scalability - bandwidth and the number of users can upgrade easily achieve further decentralization of ONU.
◆ Flexible network deployment and broadcasting network structure tree optical distribution network architecture -EPON natural fit, be flexible network deployment, the progressive realization of the bandwidth expansion and light into the copper network trends.
