Know before you buy
No, this kit is not recommended for use on coaxial lines that are already carrying active Cable TV or internet services. It is designed for dedicated, unused coaxial wiring to avoid signal interference.
The GCA-1200-KIT supports a physical layer (PHY) rate of up to 1200Mbps. Actual throughput will depend on the quality and length of your existing coaxial cabling.
No, the setup is straightforward and designed for plug-and-play functionality. Once connected to your coax and Ethernet ports, the devices automatically establish a link.
Yes, the system uses AES 128-bit encryption to ensure that your data remains private and secure as it travels across your coaxial network.
This kit is an excellent companion for FTTH deployments. You can use it to extend your high-speed fiber connection to other rooms in your house where you don't have Ethernet wall jacks, using the existing coax lines already in your walls.
