        GDOU2020 Two-in-one EOC Master


        Overview        GDOU2020?series two-in-one is a multimedia local access device that based on IEEE P1901/HomePlug AV、EPON and other technologies.Its main function is to receive IP data signal ,and IP data signal be modulated by OFDM,then the modulated signal and TV signal mixed to coaxial cable for transmission,The multimedia signals are transmitted to users over the existing CATV coaxial network.
               This node integrates EOC、ONU、TV & DATA functions.. GDOU2000 series two-in-one internal EOC module adopts a hot-swappable modular design with high isolation,configuring by demand ,networking flexibly ,upgrading smoothly.Initially
               The access rate of users’ bidirectional network modification is low, and each module has wide coverage. In the later stage, to meet the needs of users for high bandwidth and high permeability, modules can be added and each module will be covered thinly.The network does not need to be rebuilt.
               Supports existing tree and star CATV networks with high bandwidth, long transmission distance and good network adaptability. In addition, it also has high reliable lightning protection and peak relief circuit to ensure long-term stable and reliable operation of the system network. Features         Apply HomePlug AV technology(IEEE P1901)
                Speed up to 500Mbps on physical layer
                OFDM modulation technology has good anti-noise ability and performance
                through the branch distributor, there is no need to change the existing HFC network
                Support VLAN, comprehensive QoS quality assurance
                Flexible and convenient installation, plug and play
                Supports MIB libraries based on radio and television standards, including SNMP V1, V2, and V3 Technical Specifications
