DC remote power supply system consists of a central office terminal (COT) and a remote terminal (RT).
The power of COT can be boosted from DC 48V to DC 220~410V(adjustable) and transmitted to RT by hybrid optical and electrical cables,
and then dropped to DC 48V(DC 280V might be converted to AC220V) to supply to the loads(RRU, optical fiber repeater, small micro base station, ONU, etc.).
In this way, maintenance-free power is all-weather supplied.
Applications
1.Point-to-point
Scenario: network with single RRU or multple RRUs.
Applicable to the situationwhere RT devices are gathered at one point but far away from COT.
1-COT 2-ODB 3-Hybrid optical and electrical stranded loose tube cable 4-Joint box for hybid cable.
5-ODB((lightning-proof) 6-RT 7-Hybrid optical and electrical tight buffered patch cord 8-RF patch cords.
