The RPD-OPT complements DELTA Electronics' product portfolio with 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 in the direction of the end towards the end customer and aims to improve the efficiency and performance of broadband networks through higher data rates and signal quality.

At the DAA, optical fibres are preferably used as digital signal feeds to R-PHY, which distribute the user data further to the end customer via purely coaxial networks. As fibre optic expansion progresses, more and more of these costly devices are required, which supply fewer and fewer end customers. In the case of FTTB expansion, this will be required in every home. It is not yet foreseeable that essential key components will become cheaper to procure as demand increases and the current business model will no longer work. With sufficiently large network segments, the costs of price-intensive key components such as the R-PHY can be spread across many connected customers. A single FTTB connection is difficult to refinance this investment. Alternatively, the RPD-OPT is not installed at the end of the fibre optic line, but in POPs or street cabinets. The direct conversion to analogue optics in a combined device maintains the good signal quality even over long distances and ensures reliably high data rates.

With the RPD-OPT, the number of connected customers or the billable bandwidth requirement continues to determine the network investment.
