OLP光路保护，主备路由切换业务不中断
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">1、光传输中什么是双路由？</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">双路由<span style="color: black;">便是</span>两条<span style="color: black;">区别</span>的光缆从A机房到B机房<span style="color: black;">选取</span>一条传输，当一条路<span style="color: black;">显现</span>故障、自然灾害时，就会<span style="color: black;">选取</span>另一条路传输。<span style="color: black;">例如</span>A机房在广州，B机房在北京，路由一为广州-武汉-北京，路由二为广州-上海-北京，光缆就相当于水管，<span style="color: black;">通常</span><span style="color: black;">状况</span>下我<span style="color: black;">能够</span>从广州出发到武汉再到北京，当这条路<span style="color: black;">显现</span>问题，<span style="color: black;">例如</span>水管断了，这个时候我就走路由二，给予路由一充分的维修时间。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">2、OLP是什么？</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">OLP即光纤光纤线路自动切换<span style="color: black;">守护</span><span style="color: black;">安装</span>，<span style="color: black;">倘若</span>光缆比做水管，水是数据流量，<span style="color: black;">那样</span>OLP就相当于一对阀门，您即<span style="color: black;">能够</span>手动切换流向，<span style="color: black;">亦</span>能让它自动切换<span style="color: black;">守护</span>。简单<span style="color: black;">来讲</span><span style="color: black;">便是</span>先设一个优先的路由，<span style="color: black;">例如</span>路由一距离就短为主路，路由二距离长，不常用<span style="color: black;">做为</span>备路，当路由一<span style="color: black;">出现</span>不可控的<span style="color: black;">劫难</span>、老化<span style="color: black;">或</span>人为损坏时，两端的OLP能在25ms内快速切换到备路，保持数据流量的稳定连续性。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">3、OLP的应用位置</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">OLP前端对接要<span style="color: black;">守护</span>的数据，在出站点光纤之前，后端对光纤线路进行<span style="color: black;">守护</span>。即在出站点之前能切换至<span style="color: black;">区别</span>的管道，管道即是主备光缆。</p>
