Connecting Optical Fibers

Connecting Optical Fibers


Never look directly into an optical module or the ends of optical fibers. Optical modules and connected fibers emit laser radiation that can cause eye damage.
  • Before deploying optical fibers, test optical fiber connectivity.
  • Keep signal cables more than 10 cm away from power cables.
  • Optical fibers routed in a cabinet must be protected by a corrugated pipe. The bend radius of an optical fiber must be at least 20 times larger than its diameter. Generally, the bend radius of optical fibers should be no less than 40 mm.
  • Ensure that fiber connectors are tidy and clean to ensure normal communication. If a fiber connector is contaminated, clean it using a piece of fiber cleaning fabric.

Tools and Accessories

  • ESD wrist strap or ESD gloves
  • Corrugated pipe
  • Fiber binding tape
  • Marker
  • Engineering labels for optical fibers
  • (Optional) Tweezers


  1. Determine the number and type of ports to be connected and plan the cabling routes.
  2. Select optical fibers of appropriate modes, quantity, and lengths according to the optical module types, number of ports to be connected, and measured cabling distance.
  3. Attach temporary labels to both ends of each optical fiber and number them corresponding to port numbers.

    For the operation procedure, see Engineering Labels for Optical Fibers.

  4. Wear an ESD wrist strap or ESD gloves. Ensure that the ESD wrist strap is grounded and in close contact with your wrist.
  5. Remove dust plugs from an optical module and dust caps from the optical fibers to be connected.

  6. Connect the optical fiber to the optical module.

    Connect the receive and transmit ends of the optical connector according to the identifiers on receive and transmit bores of the optical module. Do not connect the two ends reversely.
    To connect optical fibers to an optical module, align the fiber connector with the bores on the optical module and insert the fiber connector. When you hear a click, the fiber connector is securely connected. See Figure 8-2.
    Figure 8-2 Connecting optical fibers to an optical module
    To remove optical fibers from an optical module, gently push the fiber connector, and then pull the fiber connector while pressing the locking clips. Do not directly pull the fiber connector with force. See Figure 8-3.

    If many optical fibers are connected to a switch with a high port density, use the tweezers delivered to remove optical fibers.

  7. Bundle optical fibers. Arrange the optical fibers to make them parallel and bundle them with fiber binding tape at an interval of 150 mm to 300 mm.
  8. Replace all the temporary labels with permanent labels on the optical fibers.
