Two notable solutions have evolved in response to the increased need for ethernet connectivity over existing coaxial cable infrastructure: MoCA (Multimedia over Coax Alliance) and BroadR-Reach. While both technologies strive to allow Ethernet over coaxial cable applications, they are different in a few ways.
The Multimedia over Coax Alliance created MoCA in 2004 as a standard for networking over high-quality coaxial cable. The technique was initially designed for domestic purposes, allowing IP television to be distributed in houses using existing coax wiring. MoCA devices are now utilized as an ethernet link over coax cable.
The maximum transmission distance of a MoCA device is determined on the version of MoCA employed as well as the quality of the existing coaxial cable infrastructure. It's important to note that the actual transmission distance can be influenced by a variety of factors, including the quality of the coaxial cable. The smaller the available bandwidth, the greater the distance. The existence of splitters or other devices, the type of MoCA adapter used, and the quantity of interference from other electrical equipment will all have an impact on transmission quality.
Transmission speeds will also vary amongst the different products on the market. The MoCA transmission establishes a shared half-duplex link between any devices that are directly linked. As a result, the number and type of MoCA devices and endpoints will have an impact on the total available bandwidth and speed.
BroadR-Reach technology, developed by Broadcom, is an ethernet physical layer that was initially designed for ethernet over twisted-pair cable in automobile applications. NVT Phybridge used BroadR-Reach technology to create a product set that uses the BroadR-Reach signal format to enable rapid ethernet transmission across single-pair UTP, multi-pair UTP, and coax cable over long distances.
The NVT Phybridge CLEER24-10G switch extends ethernet connection over new or existing coax cabling infrastructure, offering fast ethernet (100Mbps) connectivity over lengths of up to 915 meters (3,000 feet) and 10Mbps connectivity over distances of up to 1,820 meters (6,000 feet).
In contrast to MoCA, the CLEER24-10G switch (which employs BroadR-Reach technology) offers a dedicated 100Mbps full-duplex transmission per downlink port. As a result, no bandwidth sharing or degradation occurs. Furthermore, the CLEER24-10G switch has a greater range than MoCA devices. At long distances, single-pair UTP, multi-pair UTP, and coax cable are used.
Both the CLEER24-10G switch and the MoCA technologies are intended for high-speed data transfer, but they are built for distinct sorts of use cases and use different transmission technologies. The CLEER24-10G managed switch is an enterprise-grade solution that provides PoE+ with layer 3 capability, whereas most MoCA devices are unmanaged single-channel devices.
While MoCA has typically been used as a residential networking solution, the CLEER24-10G switch delivers durable and secure ethernet over coax over great distances, making it ideal for industrial, commercial, and business network applications. Use the CLEER24-10G switch to quickly and simply enable IP cameras and WiFi access points. In contrast to MoCA devices, which do not scale well owing to signalling format and crosstalk concerns, the CLEER24-10G switch (using BroadR-Reach technology) delivers good scalability and performance over long distances.
