Window: Device Box [FDB]
Device Box window (fig 1) displays detailed
schematic diagram of FDB (Fiber Distribution Box) and allows us to connect
cable fibers to connectors within FDB as well as making further connections,
using patch cables, with various devices which can also be located in
FDB.
When it comes to fiber-optics access networks (GPON), FDB is used to accept
incoming fiber (coming from the CO) split it, using one or more cascading
splitters, and than forward it to cables connecting end users (drop).
Besides that, we can use this window to organize or reorganize the structure
of FDB itself. This includes adding new and/or deleting existing elements
within FDB (modules, splitters, devices...).

Figure 1
Window can be opened in following manner:
- by calling Splicing command
and than clicking on a FDB symbol on a site plan drawing or
- by double-clicking on a FDB symbol while we are on the schematic
diagram (i.e. TCG
Optic View)
| Tip: |
You can navigate through Device Box
window by using mouse wheel - roll to zoom (+/-) and press to
move working area (pan).
Double click on a wheel to zoom extent.
Level of details displayed depends on a zoom level - closer we
are - display is more detailed.

Window elements
Device Box window is divided into three
units:
- Cables:
On the left side there is a slide bar with a slider that contains all
available cables.
This means - all cables terminated at FDB be it incoming or outgoing
- Connectors and
splice box
Central part is reserved for connectors that accept OSP cable fibers
(on the left) as well as patch cables (on the right).
On the bottom we shall find splice box which is used to directly splice
fibers or to terminate unconnected fibers.
- Devices
On the right side there is a unit with devices (splitter, OLT, ONT...).
Patch cables that connect devices with patch panel or splice box (central
part) are located left from the devices.
Patch cables that connect devices to each other are located right from
the devices (i.e. cascading splitters).
All these units are displayed in a form of hierarchically organized
elements.
Note: Elements marked with (*) do not have corresponding equivalent in
the real world be it physical or logical.
These are merely TeleCAD-GIS auxiliary elements meant to facilitate ease
of use.
Cables:

Cables are shown in a form
of hierarchically organized elements:
- Slide bar*
- Slider*
- Group of all cables*
- Cable (individual)
- Buffer tube
- Fiber
Slider, which can be moved along the vertical axe, carries cables
with their sub-elements.
The purpose of the slider is to enable moving cables closer to
a location where the splicing is performed. Slider can be moved
by double clicking on a slide bar or by dragging the slider.
Cables, buffer tubes and fibers can be moved (drag and drop).
By moving elements that contain sub-elements, sub-elements are
moved too (i.e. by moving a cable, buffer tubes and fibers are
moved too.)
The splicing is performed by dragging a fiber(s) to a connector(s)
or to a splice points of a splice box.

by a double click. This way we can adjust the display of elements
to the needs of current activity.

Usage
There are number of activities that can be performed while on the Device Box window.
Basic activities are:
(Instructions are on separate pages. Use offered links to access them.)
Commands
On the FO splicing schematic window
we can use number of commands.
They can be found at:
- Main menu
- Context menus (opened by
a right click on various elements)
- some commands are executed on a mouse
double-click.
Main meny:
File > Save
Saves the changes made on the Device Box
window.
File > Exit
Closes the Device Box window prompting us
to save the changes.
Context menus - right click on a...

click on a Cable:
- Exclusive edit
Expands all elements of selected cable (i.e. buffer tubes and
fibers) so that they and their connections become visible
while collapsing all other cables. This way we can more easily
focus on the fibers we are working with.
At that moment, top bar displays Exclusive
mode off command that turns off this mode.
- Show cable
Locates and displays on a site plan selected cable. Cable on
the site plan shall also be selected at that point.
- Expand tubes
Expands all buffer tubes of the cable so that all its fibers
become visible.
- Collapse tubes
Collapses all buffer tubes and thus hides the fibers of the
cable.
Buffer tubes are still visible.
- Select connected fibers
Selects cable fibers that are terminated on FDB ports or in
its splice box.
Tip: by selecting in this way and than by dragging the fibers
back to cable (cable's white field) we can disconnect all
cable's fibers in one move.
While doing so, take great care not to unintentionally
disconnect fibers you did not mean to disconnect!

The following set of commands, that can be invoked from the context
menu, relates to several different hierarchically organized elements that
make FDB inner structure.
The role of these elements is to accept fibers of OSP cables and inner
patch cords. These are: patch panels, splitters, various other devices
etc.
The last element in this hierarchy is a connector (i.e. port) whose context
menu differs from these and is described earlier in the text (first passage
above).
