After pulling / placing the cable, the installer prepares the cable ends for splicing or termination.

Installers protect buffer tubes & fibers, so this principle means that the jacket ends inside the enclosure, not outside.

The buffer tubes & fibers are not designed to withstand exposure to the working environment. Any improper sealant can attack the primary coating of the fiber.

The installer should use a fiber-optic cable sealant. A good idea is to put heat-shrink tubing over the end of the jacket, this conceals any uneven preparation sealant trimmed with the jacket.

This allows an installer to be ready for an end preparation.
