Fibre Optic “PON” importance explained.
Fibre Optic Networks
Fibre Optic Cable is used for transmitting data via a light-signal, everyone understands this.
But, not everyone is aware that there are different ways to allow these signals to reach their intended destination.
As such, there are two kinds of fibre optic networks that are used to reach this goal:
§ Active Optical Network (AON)
§ Passive Optical Network (PON)
In this article, our focus will be on the second network type.
Herein, we will see why the Passive Optical Network is gaining importance today.
Fibre Optic Passive Optical Network:
A Passive Optical Network (PON) is the technology that is being employed in the telecom industry.
They use this to implement a point-to-multipoint framework. Typically, a PON fibre optic network will be able to serve a lot of endpoints from one optic fibre.
This is made possible through unpowered splitters.
The end result of this type of fibre optic network is that there is no necessity for each customer to be linked to the hub using their own distinctive fibre as they can share one fibre between multiple users.
Fibre Optic Passive Optical Network components?
Typically, the PON network will contain multiple “Optical Network Units” or ONUs and “Optical Line Terminations” or OLTs.
In general, the OLT will be placed in the central office of your service provider, with up to 32 ONUs placed as close as possible to the end receivers.
The term “passive” represents the fact that when the fibre network traverses there is no need for active electronic parts or power.
Therefore the passive optical network allows expensive hardware components to be shared.
To do this a splitter will take input and divide the signal to pass on to multiple users.
Fibre Optic Passive Optical Network advantages:
There are lots of advantages associated with deploying a passive optical network.
Some of them include:
§ Decreased operational, installation and network energy costs.
§ Reduced network infrastructure requirements.
§ No need for network switches.
When you deploy a PON network, it will replace a bunch of copper wires with smaller and cost-effective single-mode fibre optic cable.
Which enables for longer distances between a PC and data centres.
Another benefit is that it gives you a far more secure connection than copper can.
Why should you test the PON before Deployment?
It is very important to test the installation of a Passive Optical Network before deployment.
This is because the degree of reflectance inside the network should be within acceptable parameters to meet customer’s expectations.
If you do not do any testing, and the reflectance and loss of signal are too high within the network, it may cause severe performance problems.
You can test the Passive Optical Network using equipment called a “PON Power Meter” which tests the wavelength frequency that is to be used in the network in such a way that the problems (if present) will be highlighted immediately.

As a PON “passive optical network” offers many advantages.
Because of these advantages, it has gained a lot of attention from service providers and is being widely deployed today.
