The metal components of the optical cable should be electrically disconnected at the joint

In installations where an optical fiber cable is exposed to contact with electric light or power conductors and the cable enters the building, the non–current-carrying metallic members shall be either grounded as specified in 770. 100, or interrupted by an insulating joint or. Sheath Retention - The cable sheath should be secured so that it will not pull out of a closure when subjected to a pull out force of 445 N (100 lbf). The sheath retention requirement is to ensure the closure clamping hardware can isolate fibers and fiber optic splices from tensile stresses applied. The grounding and bonding of the metallic components in an optical fiber cable and the supporting metallic messenger is essential to ensure the safety of workers and equipment.

In which year were cables replaced by optical cables

1980s - Global Expansion: By the 1980s, fiber optic cables began replacing copper cables in major communication networks, particularly for long-distance telephone lines and undersea. (Awarded Nobel Prize in 2009) Ethernet was invented at Xerox Palo Alto. Since I was involved in fiber optics starting in the late 1970s, much of this is from personal experiences and memories. Dates, of course, are often approximate, as putting a firm date on the introduction of a new technology is often impossible. For New England companies weighing cabling upgrades, seeing that arc of progress makes it easier to trust that fiber will.
