#DicasOZmap | Power part 2: Attenuation

In the second part of the “Power” series, we will learn how to configure the attenuation of each of your equipment.

Attenuation represents the measure of signal loss that occurs progressively as the distance traveled or even with other factors, such as curvatures, mergers, among others.

Considering that the equipment in a network already has a factory attenuation, OZmap allows you to establish a standard attenuation for your cables, splitters, DIOs, connectors and fusions, ensuring that your project is documented as accurately as possible and that the calculated power that will be reaching your customer is close to reality.

The first element that we will learn to configure will be the cables, and for that, your first step will be to access the left side menu, go to the “Types” category and select the “Cable” option.

On this page, you can configure detailed fiber optic cable information as per the supplier's specifications. In addition to the brand, model and description, an attenuation per km traveled can be entered. In this way, every time this type of cable is used, the power will be reduced automatically.

These settings can be added either in new cable types, through the “New cable type” button, or through the “i” icon located at the end of the line for each cable type, which will take you to the details of the cable. type, allowing you to change the information already added.

In the case of the example below, for each kilometer traveled, 0.4 dB of power will be lost.

Now when we talk about splitters, It is important to remember that we have two types: balanced and unbalanced. Balanced has the same attenuation on all output ports and can be configured similarly to cable types. You must go to the “Types” category and select the “Splitters” option, being able to configure a new type or edit an existing one.

From there, you can add the amount of power lost in the “Attenuation” field. This value will be applied to all outputs.

The unbalanced splitter is limited to only two output ports that do not have the same signal losses. By configuring it, you will be able to set the attenuation on each of the ports and, visually, the output with the highest attenuation will always be signaled inside the box by the white circle.

In both cases, we recommend that the configured attenuation is equivalent to the attenuation of the splitter added to the attenuations of its input and output fusions/connections, making it not necessary to apply these elements before and after passing a fiber in this equipment.

This is also the case with the DIO, where you can add the value of the attenuations suffered by the signal inside and assign them to the equipment, causing the signal to leave it with this attenuated value without needing to add extra elements to make this representation. In the example below, my signal will have a total loss equivalent to 0.7 dB.

Finally, we have the mergers and connections, which can be configured in their respective buttons.

To add an attenuation to these elements, just access their details and fill in the field according to the manufacturer's indication. Every time one of these pieces of equipment is used in a fiber, this value will be discounted.

Now that all your elements are properly documented, you can use the power calculation tool, which will show you the entire path taken by your signal to the point you are measuring. This can be done either from the cashier or from the customer.

In the button below, you can access a video that follows the entire process from the OLT, shown in the first part of this tip (if you haven't read it, click here), up to the power calculation.

This was the last part of our power tip, we hope you can take advantage of it for your network. So, how about starting to configure your elements?
