Protection Requirements for Suspended Optical Cables

Home / Protection Requirements for Suspended Optical Cables

163 describes criteria for the installation of optical fibre cables defined in Recommendation ITU-T L. Recommendations for Fiber Optic Cable Installation Where reels are supplied with protective material fitted over the cable, the protection should remain in place until the cable will be installed. The 2020 edition of the NEC introduced a new Article into Chapter 8, Article 800, General Requirements for Communications Systems and renumbered the previous Article 800, Communica ions Circuits as Article 805.
