Characteristics: Ethernet over Coax Adapter | 1200Mbps | Single Device 


NexusLink’s Ethernet over Coax Adapter (GCA-1200) is the first standards-compliant Ethernet over Coax adapter. It allows users to extend a local area network via existing coax cables and therefore provides an inexpensive option for a fast, wired, Internet connection.

Existing coaxial cables are already installed throughout many homes and businesses. When these existing coaxial cables are NOT being used for passing Cable TV/Cable Internet services, these coaxial cables provide a perfect physical medium to create a high performing Internet connection. The combination of low interference coaxial cabling plus the efficiency of the video-optimized standard enables the best real-world Internet performance.

Please Note:

  • The GCA-1200 will coexist with most services such as Broadband, Satellite, and FTTx, however, it is not recommended in environments where Cable Services (Internet/TV) are being used.
  •  A minimum of 2 adapters are required to make a connection. This product comes with 1 adapter. If this is your first coax adapter, please order the GCA-1200-KIT.



* Limitations may apply, see order for details.
