The clever CAPEX & OPEX saver for efficient broadband networks
The RPD-OPT DELTA Electronics' product portfolio is complemented by the existing Remote PHY (R-PHY) within the Distributed Access Architecture (DAA).
DAA refers to the relocation of the physical network interface (PHY) from a central headend or hub towards the end customer and aims to improve the efficiency and performance of broadband networks through higher data rates and signal quality.
At DAA, fiber optics are primarily used as the digital signal feed to R-PHYs, which distribute user data to end customers via purely coaxial networks. Due to the ongoing expansion of fiber optic networks, more and more of these expensive devices are needed, serving fewer and fewer end customers. In the case of FTTB deployment, this device is required in every building. It is not yet foreseeable that essential key components will become correspondingly cheaper with increasing demand, and the current business model is no longer viable. With sufficiently large network segments, the costs of expensive key components like the R-PHY can be spread across many connected customers. A single FTTB connection struggles to recoup this investment. Alternatively, the RPD-OPT is installed not at the end of the fiber optic link, but in POPs or street cabinets. The direct conversion to analog optics in a combined device maintains good signal quality even over long distances and ensures reliably high data rates.
With RPD-OPT, network investments will continue to be determined by the number of connected customers or the billable bandwidth requirement.
