#DicasOZmap | Power part 1: The importance of the OLT

In the first part of the “Power” series, learn more about the importance of documenting this equipment.

The OLT is the only active device within OZmap. This means that, in order to represent the signal passing on your network, it is necessary to add it to your POP.

Making this record can help you in several ways, allowing, for example, inside your box, you can know which fibers are on and which are off. In the visualization by numbers mode, the fibers that are filled will indicate those that are receiving a signal from the POP and those that are leaked, the opposite. In the image below, we can see that fibers 1 and 6 are off, while the rest are lit.

Changing the view type can also let you know which direction your signal is heading. This can be done by going to the top left and clicking on the views icon, similar to the image below.

In a network without power passing, all fibers will have the same signal representation.

Already in a network with the OLT documented, the icon will be changed to arrows that will indicate the direction the signal is going. In the case of our example, the signal is running from left to right.

To better understand the visualization of the fibers in the boxes, click here. We have a very educational video that can help you.

Another thing that the OLT documentation allows you to do is calculate the power that passes through each element and arrives at your client. With this, it is possible to have greater control of the power raised in the field or by integration compared to the projected one.

To make the calculation, you can open the desired box, select the tool “Calculate power”, indicated in the image below, and click on the splitter, client or fiber that will be calculated.

In this way, a new window will open, showing the light route to this particular point, indicating the incoming and outgoing power and each point the signal passed through, with distance information in meters and attenuation of each equipment so far. . In part 2 of the series, we'll show you how to document the attenuations, allowing the calculation to be even more accurate.

you can check here more details about Box editor and power in the boxes.

You can also check the calculated power of the client in a field of the same name, within the details of your network.

The “Power extract” button, also marked in the image, will allow you to see the path taken in more detail, similar to the resource inside the box.

In the sketch, this information will also be present.

These processes will only be possible due to the use of the OLT in my documentation.

Note that in the sketch there is the “Active” field, indicating that the client is receiving a signal and which port is feeding it, this can be identified both by the power calculations and with the lighting tools. Inside a box, when clicking with the flashlight tool on a splitter, cable, client, or fiber lit, in the opposite direction of the signal, the lighting will follow the path to POP, indicating exactly where the light comes from. This is also possible to be done without the OLT, but with its documentation this process becomes much more effective and closer to reality.

But I use other active equipment within my network, now what?

At the moment, it is recommended to create a wildcard OLT type, with only one port, which allows the passage of power to other equipment in the system (to learn about creating OLT types, click here). If, for example, you want your switch to have an active port, this equipment can be created with one more port, specifically intended for connection to this OLT.

clicking here, you can check how to add an OLT to your POP and work within it.

With so many advantages, how about starting to document the OLT on your network?
