Xingtera Ethernet over Coax (EoC) / IP over Coax Adapter (Extender), based on Xingtera wired communication or chipsets, enables ultra-high-speed multi-node IP networks over all kinds of coaxial cables. There are different PHY data rate options ranging from 100Mbps, 1,000Mbps, to 2,000Mbps. Up to 16 nodes can be supported in a single network, based on a single coax cable. 

The Ethernet over coax (EoC) / IP over Coax adapters/extenders allow users to extend Ethernet, Internet, video surveillance cameras, or other IP networks, by reusing existing coax cables. Depending on the required throughput, coax cables of up to 3KM can be used for the network, thus greatly reduce costs for IP upgrade or other networking projects where Ethernet cables cannot support the required distance or optical fibers cannot be installed easily. In addition, these adapters require very little installation effort or initial setup. Multi-node networks can be established automatically, while easy configuration can be performed by webpages or configuration tools.

Xingtera Ethernet over Coax (EoC) / IP over Coax Adapter/Extender integrates a BNC coax connector and an RJ45 connector and is completely plug & play. It works under the following conditions:

  • 12V DC (External DC power supply is required)
  • BNC coax connector
  • 10/100/1000 Base-T Ethernet on RJ45 with auto-negotiation.
  • Master/slave switch (for 100Mbps model)
  • LEDs indicating
    • Power on/off
    • Coax activity
    • LAN activity

Technology Background

Ethernet over Coax (EoC) or IP over Coax is a family of technologies that supports the transmission of Ethernet frames over coaxial cable. There are several technologies that can be applied to realize Ethernet or IP communication by reusing coax cables. For example, the ITU-T standard provides high-speed (up to 1 Gigabit/s) local area networking over existing home wires, including coaxial cable, power lines, and phone lines. It defines an Application Protocol Convergence (APC) layer for encapsulation standard 802.3 Ethernet frames into MAC Service Data Units (MSDUs). 

There are many applications and systems which can benefit from Ethernet/IP over Coax technologies. IP video surveillance networking is one of the major applications. High-speed multi-node network connections can be established over a variety of coaxial cable types in different situations in order to save labor and cable cost, including

  • New extended network connections 
  • Cable television (CATV) and satellite cabling, including residential and hotel applications
  • Upgrading of legacy networks to 100/1000Mbps
  • Pipe and tunnel inspection, deep-sea exploration, rail, radar systems, and other niche applications

For example, a major hurdle to adopt IP surveillance camera for upgrading existing sites is the necessity of new cabling.  The cost of new Ethernet cable or optical fiber for network devices can be significant, plus the cable length limitations of Ethernet can be restrictive. However, the RG-59 or similar “analog” coaxial cable that may already be present on a site is actually a better transmission medium for digital data than the Ethernet cable that would otherwise have replaced it.  Coaxial cable has higher bandwidth but lower noise and signal loss, meaning it can carry more data for greater distances. By taking advantage of this existing infrastructure, a 100/1000Mbps multi-node over a single 75 ohm coaxial cable can be easily implemented from over 1KM apart.

The Ethernet/IP over coax devices are also very straightforward to use, with no specialist knowledge required. Upgrading an analog network cable to digital requires at least two standard Ethernet/IP over coax adapters. When two units are connected together over a coaxial cable, they establish a 100/1,000Mbps Ethernet or IP network automatically.  Only one device needs to be configured as a master, and all other units should be left as slaves. Since the adapters all employ low-power technology, they can be connected to the low-voltage supplies already installed for the legacy system. The network establishment is also automatic, and no settings such as IP or MAC address is required as the Ethernet-to-coax conversion is completely transparent.  In other words, as far as the IP camera and other network devices are concerned, they can communicate with each other over the same cable.
