The main purpose of sequential markers on fiber cables is to indicate cable length. These markers, which are printed along the length of the cable, provide a way for technicians to easily measure and keep track of how much fiber has been deployed during installation or maintenance. This feature is particularly useful in ensuring accurate measurements and preventing excess slack, which can lead to potential performance issues or difficulties in cable management. By having this information readily available, technicians can work with greater efficiency and precision, thereby enhancing the overall installation process.
