本公开涉及无线通信技术领域，尤其涉及一种有源模块、移动通信前传系统和移动通信前传管控方法。
背景技术
随着移动通信技术的发展，对无线接入网(Radio Access Network，RAN)功能进行了切分，第五代移动通信技术(5G)中的RAN架构为射频单元(Remote Radio Unit，RRU)或有源天线单元(Active Antenna Unit，AAU)、分布单元(Distribute Unit，DU)、集中单元(Centralized Unit，CU)多级架构，传送网的网络部署可分为前传、中传、回传。其中集中化网络(Cloud-Radio Access Network，C-RAN)基站的比例日渐提高。单个C-RAN有可能覆盖本地及拉远的6～10个物理站点，前传网络成为移动通信传输网重要的组成部分。
相关技术，前传主要有光纤直趋、无源波分复用(Wavelength Division Multiplexing，WDM)、有源设备组网等几种方式，这几种前传方式都存在有一个共同的缺点，无法对中间的传输链路进行监控和管理。例如，对于光纤直驱方式，传输网管无法获取中间光纤连接状态等信息；对于无源WDM方式，难以感知光分配网络(Optical Distribution Network，ODN)故障，光模块运行维护困难，只能通过人工排查；对于有源设备组网方式，有源设备与AAU、DU之间的连接缺乏管理手段。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本公开保护的范围。
首先，简单介绍下相关技术中的几种前传组网方式。
一、光纤直驱方式。如图1所示，RRU(或AAU)与DU(或室内基带处理单元(Building Baseband Unit，BBU))通过前传光模块点到点直接连接。该方式需要消耗大量光纤，以5G为例，每个物理站点通常部署3个AAU，每个AAU需要出2个25G接口，则一个物理站点就要消耗12根光纤(含上下行)，而且，光纤直趋方案，传输网管无法获知中间光纤连接状态等信息。
二、无源WDM方式。如图2所示，RRU(或AAU)与DU(或BBU)上配置彩光模块，通过无源波分复用器复用多个波长进行传输。该方式相比光纤直驱方式，在光分配网络部分可以WDM技术节省主干光纤，但是RRU(或AAU)与DU(或BBU)配备彩光模块，缺乏管理手段，对ODN故障无感知，光模块运维困难，只能通过人工排查。
三、有源设备组网方式。如图3所示，有源传输设备的客户侧与无线设备采用普通灰光接口对接，传输设备进行连接组网，以完成业务的流量汇聚和拉远等功能。远端传输设备需要取电，故仅能安装于RRU(或AAU)处解决单站业务，对传输设备的数量要求较多，部署成本高，传输设备之间的链路可以进行管理，但传输设备与客户侧RRU(或AAU)、DU(或BBU)之间的连接缺乏管理手段。
