Abstract

Deutsche Telekom introduced the project OPAL (optical access line) 6 years ago. The development of new applications for FITL (FTTH, FTTB, FTTC) leads to new challenges for power systems. For the establishment of an optical fibre infrastructure at the subscriber line level, a wide variety of possible optical fibre network topologies can be imagined. Different powering architectures must be developed including remote or local powering. This paper presents the results and performances of the powering configurations to feed the optical network units (ONU) and remote OLT. Compared to conventional powering, centralised powering with remote feeding supply was implemented to power the ONU in the field economically
