Remote power supply system in communication system

Abstract

The invention provides a remote power supply system in the communicating system which is formed by a local end power part and the connected remote power module, wherein the local end part at least comprises two local end power modules and it provides the power to the remote end after the parallel connection of each local end power module.

Description

technical field [0001] The invention relates to remote power supply technology, in particular to a remote power supply system in a communication system. Background technique [0002] With the rapid development of network communication systems, remote power supply systems have become an important technology in expanding communication services. For example, in the case of the ever-increasing demand for XDSL (X Digital Subscriber Line) services, a relatively common method to expand new services to end users on the basis of the existing digital subscriber line network is: to use DSLM ( DSL Access Multiplexer, DSL access multiplexer) equipment is more moved to the end user side. In this way, 1-2 pairs of twisted pairs or coaxial cables can be used as the uplink channel, and more users and services can be accessed through the DSLM equipment. Since the environment on the user side is complex and it is inconvenient to provide power in most cases, moving the DSLM equipment to the u...
