The basic approach to pulling fiber optic cable and copper cable is similar.
Broken fiber optic cable.
The most common damage is a broken fiber which is difficult to detect.
The glass fiber within the cable is fragile and although the cable has been designed to protect the fiber it can be damaged more easily than a copper wire.
This online session will guide you through.
While patch cables are fairly robust this cable is faulty when the door is closed but working when the door is open.
It is quite difficult to test a damaged cable making the choice of replacing your fiber optic wires the best alternative.
Thats worse than just broken.
The failure of optical fiber cable will lead to a interruption for data transmission so to fix the damaged optical cable in time is an important task.
While fiber optic wires are designed to be resistant damage still happens.
The purpose of this video is to provide training on the repair limitations of fiber optic cable issues and damage.
The image below shows a fibre optic patch where the rack door has been pressing on the patch where the strain relief ends and rather obviously bend radius has been severely compromised.
