I don't know but is there a maximum compression weight on fiber, because in some of these broadcast centers they've got cable trays of SDI that are so heavy and packed that removing a dead line is a fire hazard (because the friction of pulling the line could cause a fire).

They'd obviously need a lot less and the lines are a lot lighter but maybe folks figured if they could avoid repeating that scenario in their design, it might be a good idea :-P
