Transition to PON from VDSL and legacy broadband services

The broadband services previously used non-optical copper based access services with burst data rates up to 10 Mbps. Also they were asymmetric with much lower upstream data, compared to the downstream. While modern standards offer higher rates, they are not popular and usually data rate per subscriber is even lower than maximum bursts.


While PON is not an option for mobile users, it is giving big benefit for the fixed users with higher speed/cost ratio than available alternatives. PON is symmetric with data rates of 50-100 Mbps per subscriber and passive remote node. Benefit over VDSL is clear – 50 Mbps divided between streams and higher maintenance costs. PON eliminates active devices that that are often deployed outside with possibility of high humidity, extremely low or extremely high temperature, etc. Eliminating active equipment also eliminates all the power equipment like power cables and batteries that are necessary for active components. Should not forget energy costs and EMI/EMC that are common for active devices.


PON equipment is having bandwidth independent components capable of future network upgrades at low costs. In scenario of “fresh” installation for the greenfield it is clear, PON is having more benefits with its passive components that are environment friendly, have greater capability and lower costs. PON requires larger investment when being deployed over existing copper plant, due to the network distribution expenses. While VDSL investment is lower, PON can offer easier upgrades in the future and higher bandwidth speed.


Network providers are offering PON networks for business customers with higher speeds and lower costs compared to the DS-1 and DS-3 services. Additionally PON allows more flexible service and lower maintenance cost.

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
