How long should the fiber optic cable be left when entering the terminal box
Prepare 40-50mm of bare fiber by stripping back the buffer. This provides ample length for termination while avoiding unnecessary exposure. The Fiber Optic Association, Inc. (FOA) was founded in 1995 to help develop the workforce to build the fiber optic networks to support a rapid expansion in communications and the Internet. The charter of the FOA was to promote professionalism in fiber optics through education, certification, and. The fiber optic contractor should be able to work with the customer in each installation project through six stages: design, installation, testing, troubleshooting, documentation and restoration. The contractor must be experienced in fiber optic installations of the type involved and should be able. Because fibers are sensitive to moisture, the cable end should be covered with an end cap, heavy tape or equivalent at all times. On really long runs, pull from the middle out to both ends.
