Fiber optic cables should always be pulled by the strengthened yarn fibers inside the outer jacket. Note: Since it is optical fiber, there is no problem with electrical interference. The following "pull rules" can be used. For more information, reference the EIA/TIA 568A Spec and the IEEE 802. Maximum. The Fiber Optic Association, Inc. (FOA) was founded in 1995 to help develop the workforce to build the fiber optic networks to support a rapid expansion in communications and the Internet. The charter of the FOA was to promote professionalism in fiber optics through education, certification, and. Unwinding without pull can then lead to the loosening of individual rolls and to the consequent mutual under the pull, possibly to the uncontrolled, sharp tugging of the cable, resulting in the damaging of the optical fibres. The size of the „8“ will be determined by the size and stiffness of the cable, but 2 to. It's not uncommon to see an improperly pulled cable's jacket stretch several meters due to strain placed on the outer jacket, and a stretched jacket won't provide a secure connector termination thereby compromising the cable's performance and longevity.
