Hey everyone,
I came across a small note from an old project that mentioned the QSFP-40G-SR4-S module, and it made me think about how many pieces of hardware we work with that end up tied to certain moments or challenges. I never actually deployed that specific module myself, so I am a bit curious now.

If anyone here has used QSFP-40G-SR4-S in their setup, how did it perform for you? Did it behave consistently or were there occasional quirks that only showed up after some time? I always find it interesting how these components can feel straightforward on paper but develop their own character in real environments.

Just wanted to hear some experiences from anyone who has worked with it.
