Fiber connectors can make the use of fiber cables quite convenient. Still, some more care than with electrical cables is required to handle them.
The terminations (ends) of fiber cables are often equipped with fiber-optic connectors, which allow relatively simple plugging, as is possible with electrical cables. However, fiber-optic connections are usually more sensitive than electrical connections, and more sophisticated procedures and equipment are needed to prepare or clean them.

Various types of fiber-optic patch cables (patch cords) are available, which are terminated with standardized fiber connectors.
Long-distance cables are made by connecting multiple cables, each one being a few kilometers long. Stable connections can be made with splicing, in particular with fusion splicing.
NEC Classification of Optical Fiber Cables
There exist many variations of fiber cables, to which some classifications are applied. A common classification according to the National Electrical Code (NEC) in the United States is as follows:
