TIL that all single mode MTP/MPO connectors use APC terminations. Was a little worried when my new fiber all showed up with green connectors. Thought I just made an expensive mistake, and got the wrong cables. After a lot of searching I found one reference that said they are all APC. Looking at everyone selling them they all have the green connectors.

TIL about "Martian Source" packets. :smug:

Always chuckle when I see Martian packets term used. Not sure where you ran into it, but you should also look up BCP38 (aka RFC2827). It is a short document explaining that you should filter inbound traffic, and drop traffic with invalid IP sources.

I'm very thankful for all the guys in networking documentation that had a great sense of humor.

TIL about EAP Chaining. It allows machine and user authentication to occur within the same EAP/RADIUS session.

Please don't mistake my experience for intelligence.
