14px;">首先需要注意的是，<span style="text-shadow: rgb(247, 150, 70) 2px 2px 10px;"><strong>光模块单纤、双纤类型跟单模、多模没有任何关系</strong></span></span></p></li><li><p style="line-height: 1.75em;"><span style="font-size: 14px;">不管单模还是多模光模块，都有单纤和双纤这二种类型，单纤究其根本，<span style="text-shadow: rgb(247, 150, 70) 2px 2px 10px;"><strong>其主要是为了解决在单一物理信道上进行双向收发数据的问题，说通<span style="text-shadow: rgb(247, 150, 70) 2px 2px 10px;">俗</span>点</strong></span></span><span style="font-size: 14px;"><span style="text-shadow: rgb(247, 150, 70) 2px 2px 10px;"><strong>就是为了节省光纤，节省链路资源</strong></span>，那么这就跟你传输距离远近没关系了，距离远，光纤资源充足就可以用单模双纤，光纤资源少就可以选择单模单纤，同理距离近（室内）也可以选择多模单纤或多模双纤的光模块。</span></p><p><span style="font-size: 14px;"></span></p></li><li><p style="line-height: 1.75em;letter-spacing: 1px;"><span style="font-size: 14px;">最后使用单纤或双纤类型的模块一定要注意，<span style="text-shadow: rgb(247, 150, 70) 2px 2px 10px;"><strong>单纤的型号（不管是多模还是单模）一定要成对的使用</strong></span>（前后端型号肯定不一样，因为收发波长不一样）双纤的型号（不管是多模还是单模）前后端就无需区分型号了（区分波长）型号是一致的，但是，<span style="text-shadow: rgb(247, 150, 70) 2px 2px 10px;"><strong>双纤型号光模块在使用中一定要交叉连线！ </strong></span></span></p></li></ol><p><br></p><section class="_135editor" style="border-width: 0px;border-style: none;border-color: initial;box-sizing:

style="font-size: 14px;caret-color: red;">交换机支持单模还是多模的光模块？ </span><br></p><p style="line-height: 1.75em;"><span style="color: #e36c09;"><strong><span style="font-size: 14px;">A : </span></strong></span><span style="font-size: 14px;">交换机根本没有这个说法，只要有SFP插槽（光口）就可以插单模或多模光模块，多模单模、双纤单纤都是针对光模块而言的，交换机上插哪种模块，交换机就支持什么样的。<strong><span style="text-shadow: #f79646 2px 2px 10px;">光口的物理速率要与被插上的光模块速率适配 ，意思就是说百兆光口插百兆模块，千兆万兆同理</span></strong></span></p><p style="line-height: 1.75em;"><span style="color: #1f497d;"><strong><span style="font-size: 14px;">Q：</span></strong></span><span style="font-size: 14px;">我们海康交换机配套的光模块可以与友商互相通用吗？</span></p><p style="line-height: 1.75em;"><span style="color: #e36c09;"><strong><span style="font-size: 14px;">A：</span></strong></span><span style="font-size: 14px;">不推荐，不建议，如果实在是项目中遇到以下情况，接入层是海康交换机，汇聚层是友商（说通俗点就是需要光模块对接的另一端不是海康的交换机）那么二端必需使用同一厂家的光模块，<span style="text-shadow: #f79646 2px 2px 10px;"><strong>要么二端都用海康的光模块，要么都用友商的光模块，切不可一段用海康的，一端用友商的，各自为战，互通就几无可能了</strong></span></span></p><p style="line-height: 1.75em;"><br></p><p style="line-height: 1.75em;"><span style="color: #1f497d;"><strong><span style="font-size: 14px;">Q：</span></strong></span><span style="font-size: 14px;">交换机光口自带光模块吗？</span></p><p style="line-height: 1.75em;"><span style="color: #e36c09;"><strong><span style="font-size: 14px;">A：</span></strong></span><span style="font-size: 14px;"><span style="text-shadow: #f79646 2px 2px 10px;"><strong>只有工业交换机+光纤收发器都是内置光模块的，行业交换机和经济型的POE交换机是不带的</strong></span>，在下单时，一定要注意，如果需要用到光口，一定要额外选配光模块。</span></p><p style="line-height: 1.75em;"><br></p><p style="line-height: 1.75em;"><span style="color: #1f497d;"><strong><span style="font-size: 14px;">Q：</span></strong><strong><span style="font-size: 14px;"></span></strong></span><span style="font-size: 14px;">光口的类型，SFP、SFP+、QSFP+，有啥区别？</span></p><p style="line-height: 1.75em;"><span style="color: #e36c09;"><strong><span style="font-size: 14px;">A：</span></strong></span><span style="font-size: 14px;"><span style="text-shadow: #f79646 2px 2px 10px;"><strong>SFP就是普通的百兆/千兆光口，SFP+是万兆,QSFP+是40G(最重要的区别就是速率不同)</strong></span>,SFP和SFP+长相/大小都一样,QSFP+比较肥一点,在海康传输产品中没有单个的QSFP+光模块,只有用于交换机虚拟化配置连接的专用光缆,型号为DS-3E-QSFP-3M,3米QSFP+堆叠专用线缆(含一对QSFP+光模块),样子如下：</span></p><p>
