For field-installable connectors: After inserting the fiber, use a crimping tool (if necessary) to secure the connector to the fiber. Depending on the connector type, you may need to tighten the housing or apply a crimp to ensure the fiber is properly seated within the connector. Fiber optic cables are widely used in modern optical networks, and knowing how to protect fiber optic cables is a basic but often overlooked part of daily operation. Fiber splicing make things complicated and expensive. And it needs special protection. Innerduct provides a good way to. 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. However, common mistakes during installation still occur, and they can lead to signal loss, instability, and costly maintenance.
