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 .
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 for Tv network and television network bidirectional transformation proposed EPON + LAN solutions.
The program uses fiber billion through the EPON products, placing high-capacity metro OLT series of Tv network and television equipment in the room, place the passive optical splitter in the tree branch at the Tv network and television networks, fiber to the cell after two ways you can provide Ethernet Business: placed in the optical node ONU + corridor switch, or directly to the ONU integrated switch is placed in the corridor junction box. Yitong series ONU fiber products, including GT813 and the GT815 4FE 16FE of GT811,8FE of GT812,24FE like.
Program features:
◆ flexible network deployment of EPON network structure, in line with the characteristics of the optical distribution network broadcasting the tree can be flexibly deployed network, bandwidth expansion and the progressive realization of the light into the copper network trends.
◆ 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.
◆ simplify network level EPON fiber pure, pure digital, passive splitter features, greatly simplifying the network level and improve the efficiency of network operation and maintenance.
◆ provide integrated service access - use EPON networks, cable operators can provide high-quality broadband access, leased line, voice and other services to corporate customers, improve operating income.
