Remote line powering networks — Emerging applications and standards for RFT-V

Remote line power is rapidly becoming an acceptable alternative to local power as a means of powering Fiber-to-the-Home (FTTH), DSLAMs, G.fast, and Small Cells. This paper gives examples of existing and emerging applications for remote line powering and describes the development and consolidation of standards that support it. The RFT-V standard, predominantly a North American standard, is now being considered in locations throughout the world because of its inherent power transmission advantages when compared to the well-established RFT-C standard. This paper describes the content of the newly released ATIS standard and discusses the potential for the upcoming IEC 62368-3 standard. The paper concludes that RFT-V power architecture is safe, and that the inherent power transmission advantages will drive RFT-V to power the next generation of distributed telecommunication equipment. The consolidation towards a primary standard, is expected to ensure cost containment and a steady pipeline of product innovations that can help drive the remote line powering of emerging technologies such as 5G, small cells and G.fast.
