Connecting Optical Modules and Optical Fibers

Connecting Optical Modules and Optical Fibers

Context

Invisible laser beams will cause eye damage. Do not look into bores of optical modules or connectors of optical fibers without eye protection.

  • A router must use Huawei-certified optical modules. Non-Huawei-certified optical modules cannot ensure transmission reliability and may affect service stability. Huawei is not responsible for any problem caused by the use of non-Huawei-certified optical modules and will not fix such problems.
  • Do not over bend optical fibers. The bend radius of an optical fiber should be no less than 40 mm.
  • Do not bundle optical fibers too tight. Otherwise, optical fiber performance may be degraded, affecting communications between devices.
NOTE:
The methods for connecting optical modules and optical fibers to different routers are the same. The following uses an AR2220 router as an example to describe how to connect optical modules and optical fibers.

Procedure

  1. Gently push an optical module into an optical interface until you hear a click.

    NOTE:

    If the optical module cannot be completely inserted into the optical interface, do not force it into the interface. Turn the optical module 180 degrees over and try again.



  2. Remove the dust plug from the optical module.

    NOTE:

    Place the dust plug in an appropriate place. After optical fibers are removed from the optical module, cover the optical module with the dust plug to protect it from dust.

  3. Before connecting optical fibers, attach temporary labels on both ends of each optical fiber to identify them. For details on how to make labels of optical fibers, see Engineering Labels for Optical Fibers.
  4. Remove the dust caps from the fiber connectors. Connect one end of the optical fiber to the optical module and the other end to the remote device.

    NOTE:

    Connect the receive and transmit ends of the fiber connector according to the identifiers on receive and transmit bores of the optical module. Do not connect the two ends reversely.



  5. Arrange the optical fibers to make them parallel and bundle them with fiber binding tape at an interval of 150 mm to 300 mm.
  6. Replace all the temporary labels with formal labels on the optical fibers.
