Solutions for 4G Business - Optical Fiber Cable for Distributed Base Station

 
With the construction of 4G networks, communication cables and equipment keep extending toward the subscribers.
The power supply for equipment of remote base stations. Communication rooms and access points for subscribers have become a challenging problem.
The solution of DC remote power supply by hybrid optical and electrical cables can not only facilitate centralized construction.

And maintenance of power supply devices in the network also realizes the efficient cable transmission of electric energy and optical signals.
In addition to solving the problems mentioned above, the solution of DC remote power supply by hybrid optical and electrical cables can reduce construction costs. And maintenance and enhance efficiency.
 

Principle of remote power supply

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 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 multiple RRUs.

Applicable to the situation where RT devices are gathered at one point but far away from COT.
