Comparison of broadband remote power systems

Powering broadband networks can be implemented today thanks to different technologies as local powering [LP] with or without battery, remote power feeding [RPF], cluster powering, AC remote power feeding. All powering concepts have drawbacks and advantages strongly related to the field environment and to the telecom operators specifications. We suggest a new broadband powering approach allowing the telecom operator to choose the best adequate way to meet all field constraints while maximizing advantages of a flexible remote 48 V power supply from 360 W to 2200 W. Among others parameters to be optimized are the availability level, the efficiency, the monitoring channel (central office or remote collecting) and very low level of supply emission to avoid reducing broadband system performances.
