GDCBM710 series outdoor EOC master

Overview    GDCBM710 series outdoor EOC master equipment can mix IP data signals and CATV signal output to the cable distribution network to achieve the transmission of IP data and television program on cable.It is located on the top of the EOC network, can connect as many as 253 CNU terminal equipment, it can also be installed in the output cable line of the HFC network optical node or building distribution network input line, to provide users voice, video, data and other business.
   GDCBM710 series support remote network management, can login through WEB/SNMP/TELNET way .After loginning , they can perform centralized management of the operation to the EOC slave, such as QoS Settings, encryption Settings, statistics, status information query, and software upgrades, etc.
   GDCBM710 series provide symmetrical 350 MBPS access, occupying less than 65 MHZ, have no conflict with the frequency of the existing CATV system but reduce the mutual interference.Besides, they support the existing tree and chain type CATV network with long transmission distance, high bandwidth, good fitness to network, fully meeting the requirements of combination of three network deployed by radio and television system. Features         ● Cassette body, metal/aluminum shell, good heat dissipation and electromagnetic shielding
        ● External-type industrial-grade switching power adapter supplies power.possessing multiple function of preventing lightning strike: built-in varistor, vacuum discharge tube, TVS, multiple protection circuit for preventing lightning strike and wide input voltage range (100 ~ 240 v ).The built-in EMI filter possesses good anti-interference performance with function of preventing short circuit, overload, over-voltage.Besides, low working temperature ensures long service life.
        ● Taking up 7.5 ~ 65 MHZ frequency band signal with strong anti-interference ability and high bandwidth
        ● Modular design.Supporting1-2 paths independent data module,easy to upgrade and expend
        ● Supporting 1/2/4 paths RF input, 1/2 /4ways RF output with 5-65 MHZ / 87-1000HZ interposer
        ● Providing two 10 f/100M/1000M adaptive Ethernet interfaces
        ● Supporting the console test port
        ● Supporting as many as 253 EOC slaves
        ● can be compatible with different manufacturers’ slaves equipment based on P1901 / Homeplug AV technology
        ● Following 802.1 Q VLAN l QoS (802.1p) and the IGMP layer 2 protocol, etc
        ● Supporting SNMP centralized network management which is based on national standard MIB library (draft), can customize and expand the MIB library according to customer's need
        ● Supporting the remote online firmware upgrade
        ● Supporting 60V power feeding or 220V power supply Technical Specifications
