What is the minimum amount of slack that must be provided for splicing fiber-optic cable in underground installations?

The minimum amount of slack recommended for splicing fiber-optic cable in underground installations is 15 meters. This standard is put in place to accommodate future maintenance, ease of access, and potential expansion of the network. Providing sufficient slack ensures that technicians can maneuver the cable without causing stress or damage to the fibers, which could lead to performance issues or breaks. It also offers flexibility for potential future upgrades or repairs without necessitating complete cable replacement. This requirement reflects industry best practices to ensure cables are accessible and manageable over the long term.
