    Replacing an ACX2000 or ACX2100 Fiber-Optic Cable

    To replace a fiber-optic cable:

    1. Disconnecting an ACX2000 or ACX2100 Fiber-Optic Cable
    2. Connecting an ACX2000 or ACX2100 Fiber-Optic Cable

    Disconnecting an ACX2000 or ACX2100 Fiber-Optic Cable

    ACX Series routers have field-replaceable unit (FRU) optical transceivers to which you can connect fiber-optic cables.

    Before you begin disconnecting a fiber-optic cable from an optical transceiver installed in an ACX Series router, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser Safety Warnings for Juniper Networks Devices).

    Ensure that you have the following parts and tools available:

    • A rubber safety cap to cover the transceiver
    • A rubber safety cap to cover the fiber-optic cable connector

    To disconnect a fiber-optic cable from an optical transceiver installed in the router:

    1. Disable the port in which the transceiver is installed by issuing the command:
      [edit interfaces]
      user@router# set interface-name disable

      Warning: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

    2. Carefully unplug the fiber-optic cable connector from the transceiver.
    3. Cover the transceiver with a rubber safety cap.

      Warning: Do not leave a fiber-optic transceiver uncovered except when inserting or removing a cable. The rubber safety cap keeps the port clean and prevents accidental exposure to laser light.

    4. Cover the fiber-optic cable connector with the rubber safety cap.

    Connecting an ACX2000 or ACX2100 Fiber-Optic Cable

    ACX Series routers have field-replaceable unit (FRU) optical transceivers to which you can connect fiber-optic cables.

    Before you begin connecting a fiber-optic cable to an optical transceiver installed in a router, ensure that you have taken the necessary precautions for safe handling of lasers (see General Laser Safety Guidelines for Juniper Networks Devices).

    To connect a fiber-optic cable to an optical transceiver installed in an ACX Series router:

    Warning: Do not look directly into a fiber-optic transceiver or into the ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cables connected to transceivers emit laser light that can damage your eyes.

    1. If the fiber-optic cable connector is covered by a rubber safety cap, remove the cap. Save the cap.
    2. Remove the rubber safety cap from the optical transceiver. Save the cap.
    3. Insert the cable connector into the optical transceiver (see Figure 1).

    4. Secure the cables so that they are not supporting their own weight. Place excess cable out of the way in a neatly coiled loop. Placing fasteners on a loop helps cables maintain their shape.

      Caution: Do not bend fiber-optic cables beyond their minimum bend radius. An arc smaller than a few inches in diameter can damage the cables and cause problems that are difficult to diagnose.

      Do not let fiber-optic cables hang free from the connector. Do not allow fastened loops of cables to dangle, which stresses the cables at the fastening point.
