Connecting the Fiber-Optic Array Cables to the TX Matrix Router

 

After you have tested the TX-SIB fiber-optic array adapters, you connect the fiber-optic array cables to them. These procedures assume that you have labeled both ends of each fiber-optic array cable and routed them immediately in front of their corresponding TX-SIB fiber-optic array adapters. For more information, see Routing the TX Matrix Fiber-Optic Array Cables.

To connect the five fiber-optic array cables to the five TX-SIB fiber-optic array adapters used to connect a single T640 router:

  1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  2. Ensure that each TX-SIB fiber-optic array adapter immediately in front of each fiber-optic array cable connector corresponds to the label you attached to the end of each cable.
  3. If the receivers of the five TX-SIB adapters that you are connecting are enabled, disable them.

    The slot number can be from 0 through 4 and corresponds to the TX-SIB chassis slot. The interface number can be 0 through 3 and corresponds to the TX-SIB adapters labeled LCC0 through LCC3.

  4. Remove the dust cover from the fiber-optic array cable connector that connects to TX-SIB-0. To remove the dust cover, loosen the thumbscrew and captive screw on the connector. (Use the supplied small slotted screwdriver to loosen the captive screw.) Store the dust cover in a dust-free resealable plastic bag.Warning

    Do not look directly into a fiber-optic array adapter or a connector at the end of a fiber-optic array cable attached to an adapter. The fiber optics emit laser light that can damage your eyes.

  5. Align the cable connector with the corresponding TX-SIB adapter and carefully press it into the adapter until it stops. The cable connector and adapter are keyed to ensure proper mating.Note

    The optics in a fiber-optic array adapter are spring loaded, so you must continue to apply force to a fiber-optic array cable connector or loopback connector while securing it to a TX-SIB or T640-SIB adapter.

  6. Partially tighten the thumbscrew and captive screw on the fiber-optic array cable connector. (Use the supplied small slotted screwdriver to tighten the captive screw.) Alternate between the thumbscrew and captive screw until the cable connector is secured to the adapter.
  7. Repeat Step 4 through Step 6 for the four remaining fiber-optic array cables that connect to TX-SIB-1 through TX-SIB-4.
