Installing Optical Fibers

Installing Optical Fibers

Installing Fiber Spools and Optical Modules

  • Wear an ESD wrist strap or ESD gloves before installing optical modules.
  • Cover idle optical modules with dust caps, as shown in 3 in Figure 9-21.
  • If cabinets need to be combined, install fiber spools at a side of each cabinet before you combine the cabinets.
  • The number of fiber spools to be installed depends on the actual requirements. To facilitate fiber management and routing, do not install two fiber spools on the same side of a cabinet.
  1. Install fiber spools, as shown in 1 in Figure 9-21.
  2. Install optical modules, as shown in 2 in Figure 9-21.
    Figure 9-21 Installing fiber spools and optical modules

Installing Optical Fibers

  • The clearance between the power cable, ground cable, and signal cable must be greater than 30 mm (1.18 in.) each. The bending radius of an optical fiber must be greater than 40 mm (1.57 in.).
  • Dust caps must be installed on optical modules that are not connected to any optical fibers.
  • Do not bundle optical fibers too tightly. You must be able to conveniently remove a single fiber from the bundle.

To install optical fibers, perform the following steps:

  1. Attach temporary labels to both ends of each optical fiber.
  2. Bind the optical fibers, and then insert each bundle of optical fibers into a corrugated pipe.
  3. To mark and reinforce the edges of the pipe, wrap electrical tape around both ends, as shown in 1 in Figure 9-22.
  4. Route the corrugated pipe along the cable ladder.
  5. Lead the corrugated pipe about 100 mm (3.93 in.) in to the cabinet through the top opening. Secure the pipe to the cabinet using cable ties. See 2 in Figure 9-22.

  6. Route optical fibers along the cable tray. Remove dust caps from the optical modules and protective caps from optical fibers. Then connect the optical fibers to the corresponding optical modules, as shown in 1 in Figure 9-23.
  7. Connect the other end of each optical fiber to the Optical Distribution Frame (ODF).
  8. Coil the excess length of optical fiber around the fiber spool, as shown in 2 in Figure 9-23.
  9. Use cable ties to bundle optical fibers every 150 mm (5.91 in.) and secure them to the cable tray.
  10. Attach permanent labels 20 mm (0.79 in.) from both ends of each optical fiber, as shown in 3 in Figure 9-23.
