Connecting the TCX1000-2D8CMD to a TCX1000-RDM20

 

The TCX1000-2D8CMD has optical connectors to which you can connect fiber-optic cables.

Before you connect a fiber-optic cable to a TCX1000-2D8CMD, ensure that you have taken the necessary precautions for safe handling of lasers. See the Laser Safety Warnings for Class 1M Juniper Networks Devices.

To connect a fiber-optic cable to an optical connector in the TCX1000-2D8CMD:

  1. Remove any protective caps from the fiber-optic cable. Save the caps. Also, inspect the fiber-optic cable with a scope, and use a fiber-cleaning device to clean the connector prior to insertion.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

    Class 1M laser product.

    Warning

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

  2. Remove the rubber safety caps from the optical connectors on the TCX1000-2D8CMD. Save the caps. Inspect the fiber-optic cable with a scope, or use a fiber-cleaning device to clean the connector prior to inserting the fiber-optic cable into the Line 0 (L0) OUT port of the TCX1000-2D8CMD. See Figure 1.Note

    The TCX1000-2D8CMD is shipped with an optical terminator preinstalled in the Line 1 out (L1 OUT) port. The optical terminator is preinstalled to prevent optical power from being reflected back into the transceiver transmitter in cases where the L1 out port is not in use. If you plan to use only one of the Line ports, then you should use the L0 port (the default port). If you plan to use both of the Line ports, then the optical terminator must be removed from the L1 OUT port, and the connector must be inspected and cleaned prior to connecting the fiber-optic cable.

  3. Inspect the other end of the fiber-optic cable with a scope, or use a fiber-cleaning device to clean the connector before inserting it into any of the universal ports (U0 to U19) of the TCX1000-RDM20.
  4. You can also connect any of the eight (C0 to C7) IN or OUT ports to on compatible devices. See the TCX Series Optical Transport System Feature Guide for a list of the compatible devices.
  5. 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.
