关于RouterOS的光口兼容与QSFP类端口拆分

这里介绍下MikroTik 设备与 SFP、SFP+、SFP28、QSFP+、QSFP28 及 QSFP56-DD 光模块的兼容性。了解当前 MikroTik 设备支持的各类光模块。同时，通过 RouterOS 命令行界面提供了一些实用的配置示例，用于设置不同的数据传输速率。如需了解更详细的属性说明，请参考以太网用户手册。

MikroTik 设备与 SFP、SFP+、SFP28、QSFP+、QSFP28 及 QSFP56-DD 模块对第三方厂商设备无任何限制。尽管 MikroTik 无法确保与所有厂商的模块完全兼容，但只要第三方厂商的模块和设备符合光收发器多源协议（MSA），通常可以与 MikroTik 设备兼容。

RouterOS 默认将 SFP28 和 QSFP28 接口的 FEC（前向纠错）模式设置为关闭状态。为确保与其他厂商设备成功建立连接，可能需通过配置将其 FEC 模式启用，设置为 fec74 或 fec91。

SFP+接口与25G光模块的兼容性

当MikroTik的SFP+端口安装25G光模块建立10G链路，必须配置额外的SFP速率选择设置以避免传输过程中的数据损坏。需在SFP+接口上进行如下设置：

# RouterOS v7.12及以后版本配置

SFP+/SFP28 接口与 2.5G 光模块的兼容性

2.5G 速率从 RouterOS v7.3 版本开始支持。对于支持 2.5G 链路速率的 MikroTik 设备（配备 SFP+ 和 SFP28 接口），需要在互连设备的接口上进行以下设置。

# RouterOS v7.12及以后版本配置 
/interface ethernet set sfp-sfpplus1 auto-negotiation=no speed=2.5G-baseX 
# RouterOS v7.12前旧版本配置

QSFP+/QSFP28/QSFP56/QSFP56-DD接口支持连接速率

在RouterOS中，QSFP+、QSFP28、QSFP56及QSFP56-DD接口通过多通道技术实现高速数据传输。每个QSFP+、QSFP28或QSFP56接口均划分为四个子接口，而QSFP56-DD接口则划分为八个子接口，每个子接口对应确保设备正常运行所需的传输通道。

QSFP+、QSFP28、QSFP56及QSFP56-DD子接口的命名规则包含两部分：

"qsfpplus"、"qsfp28-"、"qsfp56-"或"qsfp56-dd-"后的第一位数字代表物理端口编号，
第二位数字（QSFP+、QSFP28、QSFP56接口为1至4，QSFP56-DD接口为1至8）则标识各个独立的传输通道。

以下是QSFP+、QSFP28、QSFP56及QSFP56-DD接口在RouterOS系统中的显示示例：

这些子接口的配置与监控方式可能因自动协商、通告速率及光模块类型（如分支缆或单纤模块）等因素而异。

PS：RouterOS在QSFPxx的多通道模块与华为等产商的设置有很大区别，RouterOS是直接将多通的子接口都暴露在interace下，例如40G模块，默认qsfpplus1-1，即第一个子接口是4通道的合并端口，如果要拆分那么分别是qsfpplus1-1，qsfpplus1-2，qsfpplus1-3，qsfpplus1-4，拆分为4个10G光口端口，需要自己准备拆分光缆。而华为默认是合并端口即interface 40GE0/0/1，当要拆分为4个子接口使用“port split split-type 40GE:4*XGE”，然后重启交换机。

请注意：启用或禁用物理端口的任何子接口都将触发整个端口组的重新配置，并重启所有通道。即该端口将中断一次，但不需要重启设备。

链路配置：

40G：可配置为自动协商或强制 40G 速率。
4x10G 和 4x1G：必须设置为强制速率模式并禁用自动协商。

从 RouterOS 7.12 版本开始，除了选择正确的传输速率外，还需指定正确的链路模式。例如，对于 DAC（直连铜缆）可能需要使用 CR4，而对于光纤则可能需要 SR4 或 LR4 模式。

/interface ethernet set qsfpplus1-3 auto-negotiation=no speed=10G-baseSR-LR
/interface ethernet set qsfpplus1-4 auto-negotiation=no speed=10G-baseSR-LR

在单链路模式下，只需配置第一个 QSFP+ 子接口，其余子接口应保持启用状态。

/interface ethernet set qsfp28-1-4 auto-negotiation=no speed=25G-baseSR-LR

在单链路模式下，只需配置第一个 QSFP28 子接口，其余子接口应保持启用状态。同样，在 2x50G 链路模式下，仅需配置主接口（例如 qsfp28-1-1 和 qsfp28-1-3），但其他子接口也必须保持启用。
