NH-310C - EoC Bridge


NH-310C is an Ethernet over Coax Bridge that is designed for home and office applications that leverage the two most popular network connections for home use: Ethernet and coaxial cable connection. It is a plug & play cost effective home networking solution that eliminates the pain in modification and high infrastructure cost, it allows Ethernet connectivity in existing facilities or homes without pulling extra cables. With point-to-point and point-to-multipoint applications, it provides Ethernet connectivity over existing CATV grade Coaxial cables in locations such as apartments, hotels and buildings that require a high bandwidth network.

It is a norm that homes and offices are equipped with wired network that simply transfer small files and shared applications, but the need for triple play services like transferring large multimedia files such as music, video, photo and deliver high speed VOIP data are ever increasing.

This is why NH-310C is designed to be a cost effective home networking solution. With the data transmission up to 200Mbps and distance can withstand 60dB of the attenuation; it meets the growing demand for high speed multimedia services. With plug & play, this simply eliminates the pain in modification and high infrastructure cost. Most importantly, to be able to support point-to-point and point-to-multipoint applications allow networking for any locations such as home, office, sports center, buildings, apartments, hotels, resorts and other places that need a high bandwidth network.

Flexible Configuration

NH-310C can connect to another NH-310C via a coaxial cable, administrators can install these devices easily for Home Networking applications. The NH-310C supports up to 10(maximum) NH-310C Endpoints.

Home Networking Application

The NH-310C has been designed to operate on the coaxial cable installed in homes throughout the world. They utilized the same cable and connectors commonly used for television.

The NH-310C has 2 x Ethernet ports. One port is used to connect to the ISP to provide Internet access and the other port is used to connect devices such as HUB, concentrator, bridge or router. The device attached to these ports must support auto-negotiation.

The 2x Coaxial connector are used to connect to TV or coaxial wall socket to another modem that connect its RJ-45 to the LAN card of another set of PC, notebook, or other internet access device or coaxial connector to TV or set top box.
The NH-310S’ coaxial connector must support the transmission of data up to 200Mbps across the existing coaxial cable and link establish under -160dBm/Hz noise floor. But make sure that the connector is inserted properly and lock.
