Connecting Optical Fibers

Connecting Optical Fibers

This section describes how to install optical transceivers on the ports and how to connect them to the peer device ports using optical fibers according to the network plan.

Installing Fiber Spools

NOTE:

Wind excess optical fibers around fiber spools for convenient cable routing and device maintenance.

Determine the locations of the fiber spools based on the device arrangement in the cabinet. Positioning the fiber spools too close to the device operation area may inhibit board insertion or removal or cabling. However, positioning the fiber spools too far away from the device may inhibit fiber spool operation.

Installing Optical Transceivers and Connecting Optical Fibers

Do not look into the optical interface of the optical module or the optical fiber connector without eye protection.

Put on the ESD wrist strap or ESD gloves before installing optical modules.

When handling optical fiber cables, take the following precautions:
  • Do not overbend optical fibers. The radius should not be shorter than 40 mm.
  • Do not bundle the optical fibers too tightly; otherwise, the transmission performance of the optical fibers and the communication between devices may be affected.
  1. Before connecting an optical fiber, attach temporary labels to each end of the optical fiber.
  2. Remove the dust cap from an optical interface and insert an optical module into the optical interface.
  3. Remove the dust cap from the optical transceiver.

    NOTE:

    Store the dust cap for future use. When an optical fiber is disconnected for maintenance, use the dust cap to protect the optical transceiver.

  4. Remove protective caps from optical fiber connectors, insert optical fibers into the optical transceiver, and connect the fiber to the peer device.

    NOTE:

    Ensure that the Tx and Rx ports are correctly connected.

    Ensure that the Tx and Rx ports on one end of the optical fiber cable are connected to the respective Rx and Tx ports on the other end.

  5. Repeat 1 through 4 to install all optical transceivers and connect all optical fibers.
  6. Wind up excess optical fibers around a fiber management tray.
  7. Use tape to bind the optical fibers together at 200 mm intervals. Use cable ties to fix the fibers along the cabling rack.
  8. Remove Affix permanent labels 20 mm from both ends of the optical fiber.

Follow-up Procedure

After you power on the NIP6800, check the connection by looking at the optical port indicator. If the indicator is on or blinking, the link is connected or data is being transmitted. If the indicator is off, the link is disconnected. Possible disconnection causes include:

  • The optical fiber is improperly inserted. Pull out the optical fiber and re-insert it.
  • The Rx and Tx optical ports are reversed. Pull out the optical fibers and re-insert them into the correct ports.
  • The optical module or optical fiber is damaged and must be replaced.
