Perhaps apocryphal/silly, but amusing nonetheless. Story goes that this means you want to be in the computer furthest from the interconnect because light travels slightly faster in straight fiber than in coiled fiber.
Apparently they have 2.6% market share for trading in the US?
I think Misdicorl meant that their story of wanting to be the furthest away is perhaps untrue, not the cables.
I work in this space and although true (this is called modal dispersion), there are compensation techniques always used in termination equipment to 'handicap' or mitigate these occurrences. Not perfect, but very, very, very small deltas. Unsure if it's enough to act upon without knowing the length from output to next input.
