在开启新内容系列之前，我们希望先简要说明 QSFP 与 QSFP-DD 模块之间的区别。在 QSFP、QSFP + 及 QSFP28 世代的标准时期，技术迭代速度相对较慢，理解 起来也更为容易；而新一代光模块与网络技术（或许从 400G 世代及更高速率开始）则正迅速变得愈发复杂。 QSFP 与 QSFP-DD：核心差异何在 （图示： FS QSFP28 与 Cisco QSFP-DD 电连接对比图 1 高清版）（图示： FS QSFP28 与 Cisco QSFP-DD 电连接对比图 1 高清版） QSFP28 与 QSFP56 均采用 4 条电通道。以 QSFP28 为例，若其包含 4 条 28G 通道（实际速率为 25G），则可实现 4×25G 的传输，即 100Gbps 光模块；QSFP56 则 将单通道速率提升至 56G（实际速率为 50G），实现 4×50G 的传输，对应 200Gbps 标准。 公众号记得加星标⭐️，第一时间看推送不会错过。 来源 ： 内容来自 编译自servethehome 。 两类光模块最大的差异或许体现在电连接层面。左侧为 QSFP28 100G 光模块，右侧为 QSFP-D ...
