RFoG (Radio Frequency over Glass) is a fiber-deep network design in which the coax portion of an HFC (Hybrid Fiber Coax) network is replaced by a PON (Passive Optical Network) architecture. Fiber to the Home / Premises (FTTH, FTTP) makes economic sense for new build, multi-dwelling units, businesses and high-use consumers.
RFoG eliminates the need for HFC nodes, RF amplifiers, and taps and passives in the network, while utilizing the existing cable headend and subscriber equipment (modems, gateways and set-tops) and back-office support systems.
An RFoG network is capable of seamlessly delivering functionality and services to subscribers in a manner that is comparable to current HFC systems.
An ARRIS RFoG network provides distinct performance advantages over current HFC networks, including:
- Proven support for DOCSIS 3.1 services
- A more economical choice for MDU and rural deployments
- Comparable to HFC performance in greenfield suburban residential deployments
- Expand upstream and downstream bandwidth and significantly extend network reach by eliminating the RF noise and ingress inherent in coax deployments
- Lower energy costs and provide a greener alternative to coaxial delivery, with the added benefit of less network downtime due to power outages
- Significantly lower operating and maintenance costs by eliminating the need for HFC nodes and RF amplifiers
- Immunity to environmental factors – such as temperature, galvanic corrosion, and humidity – that can cause coaxial cabling to degrade physically over time
- Efficiently bridge between HFC and FTTx architectures and provides the infrastructure needed to transition to all-fiber, high-bandwidth 10G PON networks
- Multiple options to eliminate Optical Beat Interface (OBI) in the network
