EOC - Ethernet over Coax Master Side Unit

EOC solutions for broadcast and TV can make a full use of current network coaxial cable, which can decrease the cost of net-building. And the solution has advantages of easy construction, less operation and fast reconstruction. The noise in coaxial network cannot influence the system transmission quality. Low cost of terminal equipment can decrease the investment of customers.

The EOC head is high bandwidth bridge equipment from Ethernet to coaxial network. It takes charge in modulating the Slave terminal equipment (EOC series) linked with it. It is often located in the position of AMP or receiver in district. Single Master can link with 10 to 253 terminal slaves, and the concurrency can reach 128 customers. The system can adapt to Chinese current HFC, and coexist with CATV, DVB digital TV.

Functional Features

TV and bidirectional data can be transmitted over one coaxial cable at the same time, so it simplifies the bidirectional reconstruction of HFC networkUses current broadcast and TV HFC network to provide the customers with digital TV, interactive TV and broadband service Easy construction, plug-and-play, fast deployment, no need for repaving cable and interrupting persons Bidirectional maximum bandwidth can be 100M; the ability of anti-noise is much higher than Cable Modem; can operate under the abominable network environmentSmall volume, low weight, adapts to family, corridor and district constructionSafe and reliable, stable operation, economy and practicalTV po can be compliant with all the mainstream CATV equipment such as splitter, TV set and optical emitter, etc.Data po can be compliant with all the Ethernet equipment such as switch, router, IP set-top box, PC and etc.Embedded system, which can set all the management configuration, such as setting IP and password, through HTTP landing
