背景技术
第五代(5th generation，5G)移动通信系统与第四代(4th generation，4G)移动通信系统相比的一大显著特征就是增加了对超可靠低时延通信(ultra-reliable and low-latency communications，URLLC)业务的支持。URLLC的业务种类包括很多种，典型的用例包括工业控制、无人驾驶、远程手术和智能电网等。对于URLLC业务，一个典型需求是在1毫秒(millisecond，ms)内发送32字节的数据的可靠性要达到99.999％。需要指出的是，上述性能指标仅是个示例，不同的URLLC业务可能对可靠性有不同的需求，比如在某些极端苛刻的工业控制应用场景中，URLLC业务数据的传输成功概率需要在0.25ms内达到99.9999999％。
传统的组网系统，各设备通过白光传输，各站点可以使用白光中的任一频带进行数据传输，随着通信技术的发展，设备间传输的数据量增加，不能满足组网系统中数据的传输需求。

具体实施方式
本申请实施例提供的技术方案可以应用于各种通信系统，例如：长期演进(long term  evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、无线保真(wireless-fidelity，WiFi)系统、未来的通信系统、或者多种通信系统融合的系统等，本申请实施例不做限定。其中，5G还可以称为新无线(new radio，NR)。
传统的分布式无线接入网(distributed radio access network，DRAN)的形式组网，如图1所示，包括：汇聚设备101和多个站点(如站点102和站点103)，站点可以包括基带处理单元(base band unit，BBU)、有源天线处理单元(active antenna unit，AAU)/射频拉远单元(radio remote unit，RRU)等中任一设备，各站点间通过光纤连接，站点和汇聚设备也通过光纤连接，各设备通过光纤连接成环进行数据传输，光纤中通过白光传输数据，站点和光纤通过路由器(Router)连接。
随着通信技术的发展，设备间传输的数据量增加，不能满足组网系统中数据的传输需求。
参阅图2，本申请实施例一个组网系统包括：
汇聚设备201和多个站点(如站点2021和站点2022)，各站点间通过光纤连接，站点和汇聚设备也通过光纤连接，汇聚设备可以为交换机或综合接入交换机(LSW)，站点可以包括基站，也可以包括其他网络设备。目前，一些网络设备的举例为：继续演进的节点B(gNB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。
本实施例中组网系统使用彩光进行数据传输，各站点通过合波分器(T2模块)与光纤相连，如图3所示，合波分器可以在光纤中的彩光中解耦出目标站点对应的频带，即波分部分，还可以将目标站点的频带的耦合到彩光，即合波部分，各站点使用唯一的频带进行数据传输，以光纤中彩光包括12波长，目标站点使用其中一个波长为例，参阅图4。
如果彩光链路预算不足，可以在彩光出入口处增加光放大器(optical amplifier，OA)，如图5所示。
如果光纤通过彩光和白光传输数据，可以在部署白光分离器，白光通过该白光分离器和彩光分离，分离出的白光可以交给第三方设备处理，参阅图6，可以理解的是，可以在部署白光分离器的基础上，添加OA，如图7所示。

同一站点可以连接一个或多个终端设备，如站点2021连接终端设备2031和终端设备2032，具体终端设备的个数不做限定，不同站点连接的终端设备可以通过组网系统进行数据传输，如终端设备2031和终端设备2033。

本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的术语在适当情况下可以互换，这仅仅是描述本申请的实施例中对相同属性的对象在描述时所采用的区分方式。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，以便包含一系列单元的过程、方法、系统、产品或设备不必限于那些单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它单元。
本申请各实施例中提供的消息/帧/信息、模块或单元等的名称仅为示例，可以使用其他名称，只要消息/帧/信息、模块或单元等的作用相同即可。
在本申请实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本发明。在本申请实施例中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，其中A，B可以是单数或者复数。
取决于语境，如在此所使用的词语“如果”或“若”可以被解释成为“在……时”或“当……时”或“响应于确定”或“响应于检测”。类似地，取决于语境，短语“如果确定”或“如果检测(陈述的条件或事件)”可以被解释成为“当确定时”或“响应于确定”或“当检测(陈述的条件或事件)时”或“响应于检测(陈述的条件或事件)”。
以上所述，以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
