Before beginning any fiber optic cable installation, planning and preparing properly is important. Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. The cable should be bent as little as possible. Failure to follow these guidelines may result in damage or attenuation increases of the optical fiber or cable.
