Description

供电方法及装置 技术领域
本发明涉及通信领域，具体而言，涉及一种供电方法及装置。
背景技术
反向供电(Power Over Ethernet，简称为POE)指的是在现有的以太网Cat.5布线基础架构不作任何改动的情况下，在为一些基于IP的终端(如IP电话机、无线局域网接入点AP、网络摄像机等)传输数据信号的同时，还能为此类设备提供直流供电的技术。POE也被称为基于局域网的供电系统(Power over LAN，简称为POL)或有源以太网(Active Ethernet)，有时也被简称为以太网供电。
随着宽带/视频等业务的发展，用户对带宽的需求进入了快速上升期，传统的xDSL等技术理论上可以提供最高100Mbps的接入带宽，在实际应用中由于距离和干扰的影响，大概可以提供1～50Mbps的接入带宽。FTTH可以提供超过100Mbps的带宽，但是光纤入户难一直是困扰运营商的一个主要问题。
基于上述问题，相关技术中推出了FTTDp(Fiber to the Distribution Point)应用场景。图1根据相关技术中的FTTDp应用场景的示意图，如图1所示，在这个场景中，光纤尽可能布放到接近用户入户的位置，如楼道/室外通讯交接箱，这个位置被称为分配点(Distribution point，简称为DP)。在DP点布放分配点单元或分配点设备(Distribution Point Unit，简称为DPU)，从DP点到用户家里仍然使用原有的线缆资源，包括电话线/同轴/电力线/以太网线等，使用的调制技术包括xDSL/G.fast/DOCSIS/Homeplug/HomePNA/G.hn等。
但是，分配点通常没有电源，且入户距离很短(通常小于250米)，从用户家里通过反向供电的方法为户外DPU供电成为比较现实的选择。图2是根据相关技术中的供电系统的框图，如图2所示，现有技术中是一个独立供电设备，加上用户的终端设备和终端电源，一共有三个设备，占用两个电源插座，连接5个接口，用户使用体验差。
