Fiber optic cables are exposed to electric, mechanical, chemical and environmental elements, so proper installation is crucial for the long-term balance and survival of fiber cables.
Cable set up should additionally meet the NEC(National Electric Code) and neighborhood constructing codes. NEC indicates that fiber optic cables may be positioned within the identical raceway, cable tray or enclosure with CATV, smartphone, communication circuits and Class 2 and 3 remote manage signaling circuits.
Note that you have to in no way placed the fiber optic cable inside the same enclosure that houses electric terminations.
What are conduits?
Conduit is a tube or trough for protective electric or conversation wires and cables. It can be a stable or flexible tube in which cables are run. They house and defend the fiber optic cables in addition to every other type of information or communique transmission line.
Underground conduits are also called ducts and include one or extra conduits spaced carefully together. They are often buried without delay within the ground in concrete casing. Duct traces terminate in underground vaults called manholes. Conduits are made of fiber, PVC, PE and other substances.
Above floor conduits are product of metal or nonmetal materials. They can be utilized in uncovered or hid places aboveground.
Characteristics of an excellent conduit installation
1.Good mechanical residences to resist the forces imposed by cable installations
2.Observes fiber optic cables minimum bending radius
three.No sharp edges or bends touches the fiber optic cables all through the direction
four.Meets contemporary and destiny expansion requirements
What are cable trays?
A cable tray is an meeting of gadgets made from metal or other noncombustible substances that shape a non-stop, rigid help for fiber cables. Cable trays are used at some stage in the industry and they substantially simplify the installation of fiber optic cables.
Cable trays are available in numerous different types consisting of ladder kind, trough type, channel type and stable-backside type.
Ladder kind cable tray is a metallic shape along with longitudinal aspect rails connected by means of man or woman transverse contributors. The transverse individuals offer the assist for fiber cables.
Trough type cable tray is also a metal structure. It includes a ventilated backside and has intently spaced supports inside critical or separate longitudinal side rails.
Channel kind cable tray includes a one-piece ventilated or If you need an electrician strong-backside channel phase.
Solid-bottom type cable tray is a metal shape that has no openings within the backside. Integral or separate longitudinal aspect rails offer the guide for the fiber cables.
What are pull boxes?
Pull boxes are used to break up lengthy conduit lengths for simpler and lower anxiety cable pulls.
Pull containers are normally located near conduit bends and in long immediately runs. You ought to use as a minimum one pull field after each second 90° bend and in long conduit spans.
When pulling cable out of pull containers, ensure that the cable’s minimal bend radius is usually determined. Cable pulled through a corner pull field need to first be pulled into a loop because the sharp nook of the pull box can without difficulty damage the cable and the fibers.
