Maintaining the TCX1000-ILA Fiber-Optic Cables

 

Disconnecting a Fiber-Optic Cable from a Device

Juniper Networks devices 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, ensure that you have taken the necessary precautions for safe handling of lasers. See Laser Safety Warnings for Class 1M 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 connector installed:

Warning

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

Warning

Do not stare into the laser beam or view it directly with optical instruments even if the interface has been disabled.

  1. Carefully unplug the fiber-optic cable connector from the LC connector. The port will be automatically disabled when the cable is removed.Warning

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

  2. Cover the fiber-optic cable connector and the optical connector with the respective rubber safety caps.

Connecting a Fiber-Optic Cable

Before you connect a fiber-optic cable to an TCX1000-ILA, ensure that you have taken the necessary precautions for safe handling of lasers (see Laser Safety Warnings for Class 1M Juniper Networks Devices).

Also, inspect the fiber-optic cable with a scope, or use a fiber-cleaning device to clean the connector before inserting it into the TCX1000-ILA port.

To connect a fiber-optic cable to an optical connector in the TCX1000-ILA (see Figure 1):

  1. If the fiber-optic cable is covered by a rubber safety cap, remove the cap. Save the cap.

    Warning

    Do not look directly into a fiber-optic connector 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.

    Warning

    Warning

    Do not stare into the laser beam or view it directly with optical instruments even if the interface has been disabled.

  2. The TCX1000-ILA has a safety protective hinged/flap on it’s optical connectors, and a rubber safety cap, lift the hinged flap and open the cap.
  3. Insert the cable connector into the optical connector.
  4. Secure the cables so that they do not support 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. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

    Caution

    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.

Maintaining Fiber-Optic Cables

Fiber-optic cables connect to optical transceivers that are installed in Juniper Networks devices.

  • When you unplug a fiber-optic cable from the TCX1000 connector, close the rubber safety caps over the connector and on the end of the cable.

  • Anchor fiber-optic cable to avoid stress on the connectors. When attaching a fiber-optic cable to a connector, be sure to secure the fiber-optic cable so that does not support its own weight as it hangs to the floor. Never let a fiber-optic cable hang free from the connector.

  • Do not bend fiber-optic cables beyond their minimum bend radius. Bending the cables beyond their minimum bend radius can damage the cables and cause problems that are difficult to diagnose.

  • Frequent plugging and unplugging of fiber-optic cables in and out of optical instruments can damage the instruments, which are expensive to repair. Attach a short fiber extension to the optical equipment. Any wear and tear due to frequent plugging and unplugging is then absorbed by the short fiber extension, which is easier and less expensive to replace than the instruments.

  • Keep fiber-optic cable connections clean. Microdeposits of oil and dust in the canal of the cable connector can cause loss of light, reduction in signal power, and possibly intermittent problems with the optical connection.
