其中说道: The QSFP28 port 接口？啥意思？
The Cisco Nexus 3232C has 32 QSFP28 ports. 有32 个QSFP28接口？为什么叫 QSFP28?

只好Google 呗。

the alphabet soup --->以字母简称命名

The [CFP]- "C" for 100, and FP for "Form factor, Pluggable." , 当年我考了很多人C是什么意思。呵呵。应该是罗马数字。有兴趣的读者自己谷歌吧。

The QSFP28 module has an upgraded electrical interface to support signaling up to 28 Gbps signals, yet keeps all of the physical dimensions of its predecessor.
