Fiber Optic Cable Care and Use
Optical fiber cables may degrade in performance or be damaged if handled improperly. Note the following cautions and warning when handling them.
Caution 
Do not pull the cable when removing the connector.
Doing so may break the optical fiber inside the cable, or remove the cable sheath from the optical connector.
 
Caution 
Do not excessively bend, fold, or pinch an optical fiber cable.
Doing so may break the optical fiber inside the cable. Keep the bend radius of an optical fiber cable at 30 mm or more. If the radius is less, optical fiber cable loss will increase.
 
Caution 
Do not excessively pull on or twist an optical fiber cable.
Also, do not hang anything by using a cable. Doing so may break the optical fiber inside the cable.
 
Caution 
Be careful not to hit the end of an optical connector against anything hard such as the floor or a desk by dropping the optical fiber cable.
Doing so may damage the connector end and increase connection loss.
 
Warning 
Do not touch the end of a broken optical fiber cable.
The broken optical fiber may pierce the skin, causing injury.
 
Caution 
Do not disassemble optical connectors.
Doing so may cause part to break or the performance to degrade.
