背景技术
DWDM密集波分复用系统是当前最常见的光层组网技术， 通过复用 /解复用 器可以实现数十波甚至上百波的传送能力， 随着业务网络 IP化和分组化的需 求越来越多， 波分网络也从传统的点到点的线路系统逐步演变成可实现波长 智能调度的 Mesh系统， 可重构光分插复用设备（Reconf igurable Opt i ca l Add/Drop Mul t iplexer, ROADM)是实现光层重构的主要使能技术， 其可以在 一个节点上完成光通道的上下路（Add/Drop) , 以及穿通光通道之间的波长级 别的交叉调度。 目前， 基于 WSS ( Wavelength Se lect ive Swi tch, 波长选择 开关） 的 ROADM, 可以在所有方向提供波长粒度的信道， 远程可重配置所有直 通端口和上下端口， 适宜于实现多方向的环间互联和构建 Mesh网络， 逐渐成 为 4维度以上 ROADM的首选技术。
在基于 WSS的 ROADM中， 两个不同方向（即业务接收方向和业务发送方向） 之间的业务调度是通过一对 WSS实现的， 在每个 WSS中， 设置有一个端口被用 于本地信号的上下， 还设置有 N个端口用于在 N个! 0ADM模块间的网络交叉互 联， 从而实现 N个自由度的业务调度。 N越大端口之间的连接关系就越多， 要 想准确的进行业务调度， 必须准确知道哪一对 WSS的哪一对端口之间有光纤连 接关系， 如果光纤实际连接与规划的连接关系不符， 会导致业务调度无效。
现有技术中光纤的连接关系需要用户手工创建， 工作时间长且容易出错。 发明内容

102、 为获取到的逻辑光传播路径分别配置不同的波长交叉。
其中， 波长交叉的配置与光传播路径满足——对应关系， 也就是说， 每 一条光传播路径只能允许一种波长的光信号通过。
需要说明的是， 可用于配置的波长的数量和种类取决于 R0DAM系统容量。
103、 在所述接收端波长选择开端的入端口接入通信光源。
其中， 所述通信光源可以为泵浦源工作时发出的噪声光源， 也可以是人 工制造的人工光源。
104、 采集发送端波长选择开关的出端口的光信号波长。
其中， 所述采集发送端波长选择开关的出端口的光信号波长可以通过使 用光功率计测量来实现， 具体的实现方法为本领域技术人员公知的技术， 本 发明实施例在此不进行详细描述。
105、 根据采集到的光信号波长， 确定与采集到的光信号波长对应的逻辑 光传播路径。
106、 从所述与采集到的光信号波长对应的逻辑光传播路径中， 确定接收 并将所述连纤关系进行存储。
本发明实施例提供的一种获取可重构光分插复用设备内部连纤关系的方 法， 先获取接收端波长选择开关的入端口到发送端波长选择开关的出端口的 逻辑光传播路径， 然后为获取到的每条光传播路径设置不同的波长交叉， 再 采集发送端波长选择开关的出端口的光信号， 来确定达从接收端波长选择开 关的入端口到发送端波长选择开关的出端口的光信号的波长， 通过采集到的 光信号波长来确定接收端波长选择开关的出端口到发送端波长选择开关的入 端口之间的连纤关系， 避免了复杂的人工操作， 降低了人工工作量， 可以准 确高效地获取可重构光分插复用设备内部连纤关系。
实施例 2
本发明实施例提供了一种获取可重构光分插复用设备内部连纤关系的方 法， 可以应用于如图 2所示的基于 WSS (Wavelength Selective Switch, 波 长选择开关） 的 R0DAM ( Reconf igurable Optical Add/Drop Multiplexer, 可重构光分插复用设备）系统中， 该系统包括： WSS、 OA (optical amplifier, 光发大器）、 0PM (Optical Power Meter, 光功率计）。 WSS可以根据配置位置 划分为接收端 WSS和发送端 WSS,分别用于进行业务光信号的接收和业务光信 号的发送。 其中， 每个接收端 WSS都有一个入端口和多个出端口， 每个发送 端 WSS都有一个出端口和多个入端口。
基于上述基于 WSS的 R0DAM系统结构，以获取 WSS1与 WSS1' 之间的连纤 关系为例说明本发明实施例提供的一种获取可重构光分插复用设备内部连纤 关系的方法， 如图 3所示， 该方法包括：
201、 从 WSS1中的出端口 （编号为 1至 n)选取一个端口作为第一端口， 例如， 可选择端口 1为第一端口。
202、从 WSS1， 中的入端口（编号为 1至 n)选取一个端口作为第二端口， 例如， 可选择端口 1为第二端口。
203、 将依次通过 WSS1 的入端口、 WSS1 的出端口 1、 WSST 的入端口 1 和 WSS1， 的出端口所经过的路径确定为 WSS1和 WSS1， 之间一条逻辑光传播 路径。
204、 重复执行步骤 201至步骤 203 , 直至得到 WSS1和 WSS1 ' 之间所有 需要配置波长交叉的逻辑光传播路径。
需要说明的是， 根据光纤连接的单一性， 接收端 WSS 中的一个出端口只 能与发送端 WSS 中的一个入端口存在连纤关系， 具有连纤关系的两个端口是 不能够再与其它端口存在连纤关系的。 由此可知， 当光选择开关中有一些端 口正在通过业务光信号时， 在步骤 204 中获取到的所有逻辑光传播路径中， 就会存在一定数量的传播路径是不能够实现的， 故为了筒化检测流程， 提供 效率， 在执行所述步骤 201之前， 还包括以下步骤：
获取当前业务波长交叉配置信息， 其中， 所述当前业务波长交叉配置信 息用于标识接收端波长选择开关中的允许业务光信号通过的出端口和发送端 波长选择开关中的允许业务光信号通过的入端口。
根据所述当前业务波长交叉配置信息， 确定接收端波长选择开关中的未 允许业务光信号通过的出端口以及发送端波长选择开关中的未允许业务光信 号通过的入端口。
则所述步骤 201 的执行过程具体为从接收端波长选择开关中的未允许业 务光信号通过的出端口中， 选取一个出端口作为第一端口。 务光信号通过的入端口中， 选取一个入端口作为第二端口。
205、 判断所述逻辑光传播路径是否已经配置了波长交叉。 若确定所述逻 辑光传播路径配置了波长交叉， 则执行步骤 206; 否则执行步骤 209。
其中， 所述判断所述逻辑光传播路径是否已经配置了波长交叉的方法，以 步骤 203获取到的逻辑光传播路径为例， 具体包括： 判断端口 1和端口 Γ 是 否允许相同的波长通过， 若端口 1和端口 Γ 允许相同的波长通过， 则认为该 条光传播路径已配置了波长交叉；若端口 1和端口 允许通过的波长没有相 同的波长， 则认为该条光传播路径未配置波长交叉。 206、 获取所述逻辑光传播路径经过的 WSS1的出端口以及 WSS1， 的入端 口。
207、 从当前未使用的波长中选取一个波长。
需要说明的是， 已使用的波长包括正在作为业务波长使用的波长和配置 给其它光传播路径的波长。 未使用的波长为在该 R0ADM 系统中可使用的波长 除去已使用的波长的剩余的波长。
208、 将所述经过的 WSS1 的出端口光通断状态设置为允许波长为选取的 波长的光信号通过。 将所述经过的 WSS1 ' 的入端口光通断状态设置为允许波 长为选取的波长的光信号通过， 并执行步骤 210。
209、 保持当前波长交叉配置不变， 并执行步骤 210。
210、 在 WSS1的入端口接入噪声光源作为通信光源。
需要说明的是， 若 WSS1已接入了业务光源， 则将泵浦原发出的噪声光源 和业务光源一同接入 WSS1作为通信光源。
211、监测 WSS1 ' 的出端口的光信号， 并获取监测到的光信号对应的光信 号波长。
212、 ^^据采集到的光信号波长， 确定与采集到的光信号波长对应的光传 播路径。
213、 从所述与采集到的光信号波长对应的光传播路径中， 确定 WSS的出 端口与 WSS ' 的入端口之间的连纤关系， 并将所述连纤关系进行存储。
其中， 若根据采集到的光信号波长， 确定与采集到的光信号波长对应的 光传播路径为所述步骤 203中获取到的光传播路径，则认为端口 1和端口 之间具有连纤关系。
进一步值得说明的是，步骤 201至步骤 213仅描述了获取 WSS1和 WSS1， 之间的连纤关系的方法， 其它波长选择开关之间的连纤关系也可以由此方法 来获取。
值得说明的是， 上述步骤 201至步骤 213仅用于描述获取一个接收端波 长选择开关与一个发送端波长选择开关之间的连纤关系， 这只是本发明实施 例的一种实现方式， 本发明实施例提供的技术方案， 还可以用于获取一个接 收端波长选择开关与若干个发送端波长选择开关之间的连纤关系， 或者， 用 于获取若干个接收端波长选择开关与一个发送端波长选择开关之间的连纤关 系； 也可以用于获取接收端波长选择开关的一个或多个出端口与所有发送端 波长选择开关的一个或多个入端口之间的连纤关系。
另外值得说明的是， 当 R0DAM 系统没有任何业务开通运行时， 接收端波 长选择开关和发送端波长选择开关均未承载业务光信号， 也没有任何波长交 叉配置。 此时， 接收端波长选择开关和发送端波长选择开关之间的逻辑光传 播路径为由接收端波长选择开关的出端口和发送端波长选择开关的入端口之 间的全组合形成的所有光传播路径， 故可选择如下配置方法对接收端 WSS 的 所有出端口和发送端 WSS， 的所有入端口进行波长交叉遍历配置。 以接收端 WSS的出端口和发送端 WSS' 的入端口数量均为 8个为例具体说明， 配置内容 :¾口下：
选取 64 (8*8 )个波长进行交叉配置， 使 WSS1单板的每个出端口均允许 8个波长通过， 具体配置为： 从 In口接入的波长为 λ 1, λ 2, λ 3, λ4, λ5, λ 6, λ 7, λ 8的光信号允许从 WSS1的端口 1通过， 从 In口接入的波长为 λ 8, λ 9, λ 10, λ 11, λ 12, λ 13, λ 14, λ 15的光信号允许从 WSS1的端口 2通过， 从 In口接入的波长为 λ 17, λ 18, λ 19, λ 20, λ 21, λ 22, λ 23, λ 24的光信号允许从 WSS1的端口 3通过，以此类推，将 64个波长配置给 WSS1 所有出端口。
然后对 WSS1， 交叉配置， 具体配置为： WSS V 的端口 Γ 允许波长为 λ 1, λ 9, λ 17, λ 25, λ 33, λ 41, λ49, λ57的光信号通过， 端口 2， 允 许波长为 λ 2, λ 10, λ 18, λ26, λ 34, λ42, λ50, λ 58的光信号通过， 端口 3， 允许波长为 λ 3, λ 11, λ 19, λ 27, λ 35, λ43, λ 51, λ59 的 光信号通过， 依次类推， 将 64个波长配置给 WSS1， 所有入端口。
在 WSS1的入端口接入泵浦源产生的通信信号，并根据在 WSS1， 的出端口 检测到的光信号波长来确定 WSS的出端口和发送端 WSS，的入端口之间的连纤 关系。
进一步的，若波长不足 64个，则可以先判断 WSS1的几个出端口和 WSS1， 的所的几个入端口之间的连纤关系。 例如， 可以使用 25 个波长来获取 WSS1 的 5个出端口与 WSS1 ' 的 5个出端口之间的连纤关系， 然后在使用 9个波长 来获取 WSS1的剩余的 3个出端口与 WSS1 ' 的剩余的 3个出端口之间的连纤关 系。
本发明实施例提供的一种获取可重构光分插复用设备内部连纤关系的方 法， 先获取接收端波长选择开关的入端口到发送端波长选择开关的出端口的 光传播路径， 然后为每条光传播路径设置不同的波长， 再采集发送端波长选 择开关的出端口的光信号， 来确定达从接收端波长选择开关的入端口到发送 端波长选择开关的出端口的光信号的波长， 通过采集到的光信号波长来确定 接收端波长选择开关的出端口到发送端波长选择开关的入端口之间的连纤关 系， 避免了复杂的人工操作， 降低了人工工作量， 可以准确高效地获取可重 构光分插复用设备内部连纤关系。
