Estimating the term…
A Passive Optical Networks (PONs) structure and a remote node in such a structure constituting at least a part of a backhaul network for supporting a Radio Access Network, in which a number of radio base stations are connected to optical networks units (ONUs) of said PONs structure. The ONUs of said PONs structure are grouped between separate PONs of said PONs structure. The ONUs of a separate PON are interconnected passively through a remote node of the PON in order to separate inter base station traffic of X2 interfaces from uplink and downlink data traffic of S1 interface heading from/to a core network via an optical line terminal (OLT). The remote node comprises of power splitter for enabling interconnection between ONUs of different PONs of said PONs structure.
A Passive Optical Networks (PONs) structure structure constituting at least a part of a backhaul network for supporting a Radio Access Network, in which a number of radio base stations (RBSs) are connected to optical networks units (ONUs) of said PONs structure, wherein the ONUs of said PONs structure are grouped between separate PONs of said PONs structure, wherein ONUs of a separate PON are interconnected passively through a remote node of the PON in order to separate inter base station traffic of X2 interfaces from uplink and downlink data traffic of S1 interface heading from/to a core network via an optical line terminal (OLT), wherein the remote node comprises power splitters for enabling interconnection between ONUs of different PONs of said PONs structure.
A remote node of a Passive Optical Networks (PONs) structure constituting at least a part of a backhaul network for supporting a Radio Access Network, in which a number of radio base stations, RBSs, are connected to optical networks units (ONUs) of said PONs structure, wherein the ONUs of said PONs structure are grouped between separate PONs of said PONs structure, wherein ONUs of a separate PON are interconnected passively through the remote node of the PON in order to separate inter base station traffic of X2 interfaces from uplink and downlink data traffic of S1 interface heading from/to a core network via an optical line terminal (OLT), wherein the remote node comprises of power splitters for enabling connection of the remote node to ONUs of at least one other PON of said PONs structure.
The remote node according to claim 7, wherein the power splitter is adapted to broadcast uplink inter base station traffic from one or more ONUs to one or more ONUs of the PONs structure.
The remote node according to claim 8, wherein the power splitter has one uplink side and one downlink side, wherein ports of the downlink side is connected to ONUs of one or more PONs of said PONs structure and ports of the uplink side are at least connected to the OLT of its own PON and an isolator for enabling broadcasting of said uplink inter base station traffic from one or more ONUs of the PONs structure.
