REMOTE POWERING FOR FTTX VIA EXISTING WIRE

摘要

The present invention relates to a powering method, a powering system, a cabinet and a central office for powering a copper-centric fiber to the x (FTTX) architecture. The architecture comprises at least one point to point or point to multipoint optical distribution network (ODN) between an optical line termination (OLT) or first Ethernet Switch positioned at a central office (CO) and an optical network unit or second Ethernet switch positioned at a cabinet (CAB) or building closer to a network terminal (CPE). The ODN is an active or passive network. The architecture further comprises at least one signalling coaxial or twisted wire pair line between the ONU or second Ethernet switch (ES) and one network terminal (CPE). What particularly characterizes the present invention is that the ONU or the second ES is powered remotely from the central office (CO) via at least one powering twisted wire pair line extending between the central office (CO) and the cabinet (CAB) or building.
