About this episode
One hundred meters is not a measurement. It is a budget with three parts: ninety meters for the permanent link in the walls, and ten meters of patch cord shared between both ends. A long cord at the desk leaves less for the closet.
This episode takes that budget apart. Why the wall cable is solid and the patch cords are stranded, why patch panels exist at all, what actually happens on a run that goes past the limit, and what to do when a site makes the standard impossible.
The second half is installation. Bend radius, tight coils, distance from power, and the fire rating printed on the jacket. These are the practices that separate a run which certifies from a run that mostly works.
