Proof-testing of optical fibre
Cable designs minimize strain the fibre through provision of additional strength members, so even in aerial applications the actual tensile strain in fibre is kept low, typically well below 0.2%.

GENERAL INFORMATION
There are two tensile strength values used to define fiber optic cable: 1) installation (or short term) and 2) long term (or operating load). These values change depending on the cable construction and fiber
