Optical receivers in OpenComms can have multiple fiber sheaths connected to it, and the node can be segmented using the Connections Manual tools in OpenComms. This section describes the tools provided for segmenting optical receivers in OpenComms.

Open the Node Connections Dialog Box

1. From the OpenComms Fiber Tab under the Modify/Delete section, select the Connections Manual dropdown:

   

2. Select the node you wish to connect.

3. After selecting the node with manual connections, if there are multiple sheaths connected to the node, the user has the option to connect node internals to fibers or to connect fibers to fibers. The following dialog displays:

   

   Selecting No will bring up the Cross Sections Connections dialog allowing the user to connect fibers together:

   

4. Selecting Yes to the ‘Do you want to connect to node internals’ dialog will bring up the Node Connections dialog allowing the user to connect fibers to the Node Internals:

   

Adding RX/TX Internals to a Node Case

In OpenComms, nodes can be added and removed from the node casing as needed.

1. Open the Node Connections dialog on a new or existing node location connected to a fiber sheath.
   Note: The user can utilize existing internals that are pre defined in the fiber resource file to be used with a particular node model. These internals can be used for connections but the user is not required to predefine a node with internals in OpenComms.
2. Place your cursor in the right view window of the Node Connections dialog box where the node name is located.
3. Right click in the empty space beneath the node name and choose Add RX/TX.

   

4. The Edit Node Internal dialog box appears.

   

5. In the Edit Node Internal dialog box, populate Node ID and Model.
   Note: Node ID is a unique name for the new node being added and Model is the particular node model name being added to the case.
6. Choose whether a RX/TX combo will be placed or a single RX or TX internal added to the node with the radio button option.
7. Check the option for Build OS if plans are to create a named circuit with the OpenComms OS/Circuit Manager using these new internals.
8. Once the information is populated, choose OK in the Add Node Internal dialog box.
9. The node now contains new internal(s).
10. The internals are now added, select OK in the lower right hand side of the Node Connections dialog box to apply changes and close the dialog.

Create Fiber to Node Internal Connections

1. In the Node Connections dialog box, select a fiber from the incoming sheath (left view window).
2. Select an internal to connect to the incoming, selected fiber (right view window).
3. Move your cursor above either of the selected items.
4. Right click on either selected item and choose CREATE CONNECTION.
5. The internals are now connected, select OK in the lower right hand side of the Node Connections dialog box to apply changes and close the dialog.
   Note: Once a fiber is connected, it will appear in the Node Connections dialog box in bold type. Multiple fibers and ports can be selected and connected in this dialog as well by using standard Windows Ctrl and Shift keys.

Add a Splitter/MUX Device to a Node Case

1. In the Node Connections dialog box, right click in the empty space beneath the WDM/Splitter view window (middle/center window) and choose Add Splitter.

   

2. The Add Splitter dialog box appears.

   

3. Populate the device ID, Model and any other info needed and select OK.
4. The Splitter device has now been added.
   Note: Expand the newly added device to see the available ports to connect.

Connect Node Internals and Fibers to a Splitter/MUX Device

1. In the WDM/Splitter view window, select the Common port on the newly added Splitter/MUX device.
2. In the Sheaths view window, expand the incoming buffer and choose a fiber to connect to the Common port on the Splitter/MUX device.
3. Move your cursor above either of the selected items.
4. Right click on either selected item and choose CREATE CONNECTION.

   

5. Now choose an output port and its associated node internal and right click on either selected item and choose CREATE CONNECTION.
6. Continue the same steps to connect any remaining node internals to Splitter/MUX output ports.
7. The internals are now connected, select OK in the lower right hand side of the Node Connections dialog box to apply changes and close the dialog.

Editing a Node Internal or Splitter/MUX Device

1. In the Node Connections dialog box, select the node internal or splitter/MUX device to be edited.
2. Right click the device and choose Edit Splitter or Internal.

   

3. The Edit dialog box appears for the device.

   

4. Apply changes as needed and select OK in the Edit Splitter or Internal dialog box.
5. The device or internal has now been edited, select OK in the lower right hand side of the Node Connections dialog box to apply changes and close the dialog.

Deleting a Node Internal or Splitter/MUX Device

1. In the Node Connections dialog box, select the node internal or splitter/MUX device to be deleted.
2. Right click on the device or internal and choose its Delete option.
3. You will be prompted with a warning message, select OK to complete the deletion.

   

4. The device or internal is now removed.
5. The device or internal has now been deleted, select OK in the lower right hand side of the Node Connections dialog box to apply changes and close the dialog.
