One time I had a dream where I had just bins and bins of different capacitors and people kept bringing in broken routers, modems, LEDs, remote controls, toys, industrial power supply units, you name it and I would just swap out the capacitors and it would all work again like some kind of fukin wizard rewriting the runes.
I'm sorry, but the FS vendor specifies working temperature as a "case temperature".
In this situation
(Note: The FS P/N is changed from SFP-10G-T to SFP-10G-T-30, but the product is the same.),
the case temperature is specified from 0 °C to 70 °C.
Looks like the cooked module was used in a desktop fan-less class switch.
Does not compute, there is no airflow.
10GBASE-T uses a lot more power than fiber or a DAC. Those SFP+ modules definitely need some airflow.
