- keepamovin 2y agoOh shit! Thanks. Good point. That actually makes it more plausible, as K is smaller.
- segfaultbuserr 2y ago1/2 c in circuit boards (FR-4), 1/3 c in cables, two useful numbers to remember.
- keepamovin 2y agoThanks, nice! But wait - so we have 1/2 c ~ 150 km/ms in circuit board. 1/3 c ~ 100 km/ms in cable. And... 2/3 c ~ 200 km/ms in fiber? I'm a bit confused about difference between cable and fiber heh :)
- segfaultbuserr 2y agoSorry, it was a typo. I meant 2/3 (including common cables and fiber optics), not 1/3.
- Hikikomori 2y agoDepends on what kind of cable? As twisted pair network cable is at 2/3.
- segfaultbuserr 2y agoWhat an embarrassing typo! I was thinking of 0.66, and somehow I thought 0.66 = 1/3 (must've been distracted by the "2" in 1/2). I should've written 0.66 or 2/3.
