However sometimes, especially in demonstrations or in a lab environment, the cable
is rolled randomly in small turns for convenience. The randomly rolled UTP cable
suffers additional signal impairments (compared to a straight cable) and therefore the
maximal operating reach might be reduced. Rolling a Cat.5e cable around a 70 cm
fixed diameter plastic drum has just a minor effect on the FEXT (Far End Cross Talk)
when compared to a fully stretched cable. Refer to
6.1.2 Output Cable.
