Outdoor CSMA / CA Protocol CATV Optical Receiver For Ethernet And Coaxial Cable Network

 
Outdoor CSMA / CA Protocol CATV Optical Receiver For Ethernet And Coaxial Cable Network , GDCBM710
 

Overview
      
GDCBM710 series outdoor EOC master equipment based on main chip AR7410 (INT6400 optional) , 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.
