| Description
OPEM-N9720EK-XXX equipment is the active EoC network concentrator that design and develop based on HomePlug AV/IEEE P1901 technique. Bidirectional transformation on the basis of original HFC network, simultaneously transmit television and data signals on one coaxial cable, realize TV and broadband data simultaneously access. Have advantages such as long distance transmission, good network adaptability and high bandwidth. It is the first choice to develop digital TV network of radio and television system.
Performance Feature
(1) High speed: Adopt high-speed multi-carrier modulation technique, physical layer rate up to 700Mbps.
(2) Strong anti-interference ability: OFDM modulation, multi-carrier technology ensures stable data transmission in the noise environment.
(3) High security: Adopt 128 bit DES data encryption; effectively protect the data transmission security.
(4) Strong network adaptability: Adopt standard interface, signal can transparently transmit to amplifier, tap etc equipment, and realize fast installation and debugging.
(5) Rich service application types: Support EoC link multicast monitor, multicast manage the whole EoC network. Support service priorities distinction based on IP-TOS, ensure the time-sensitive application of VOD and VoIP. Support VLAN (802.1Q) standard, ensure privacy requirements.
(6) Strong network management function: Support SNMP protocol, through remote NMS, local WEB or CLI interface to manage the device. Support online configuration and offline configuration; support automatic configuration and batch configuration of network node. Provide support for the effective and stable operational network.
(7) Long transmission distance: The maximum attenuation distance of the coaxial network is 500m.
