Upgrading a network is always a challenging task, especially when balancing the need for higher bandwidth with the cost and complexity of infrastructure overhauls. Combo PON offers a solution to th.is challenge by allowing GPON (Gigabit Passive Optical Network) and XGS-PON to coexist within the same infrastructure. This means service providers can introduce faster internet speeds and more advanced services without replacing their entire network. This blog delves into how Combo PON works and why it’s a game-changer for telecom operators.
What is Combo PON?
Combo PON refers to the coexistence of GPON and XGS-PON on the same physical infrastructure. GPON, which has been the industry standard for delivering fibre-based broadband, operates at a lower speed than XGS-PON. However, both technologies can function simultaneously on the same network because they use different optical wavelengths. This coexistence allows service providers to gradually upgrade their networks by offering XGS-PON to customers with higher bandwidth needs while continuing to serve GPON customers.
For example, a service provider might offer XGS-PON to businesses and high-end residential customers who require faster speeds for applications like cloud computing, VR, and video conferencing, while keeping GPON for other residential clients.
How Combo PON Works
Combo PON allows for the integration of XGS-PON into existing GPON networks using wavelength division multiplexing (WDM). This technology allows both GPON and XGS-PON to transmit data over the same fibre line without interference. Since GPON and XGS-PON operate on different wavelengths, the two technologies remain invisible to each other, enabling seamless coexistence.
Combo PON also simplifies network upgrades. Service providers can introduce XGS-PON in select areas or for specific clients who need faster speeds without disrupting the overall network. This makes the technology an attractive solution for operators looking to avoid the cost and complexity of a full-scale network overhaul.
Deployment Strategies
The flexibility of Combo PON allows operators to focus on high-revenue areas or high-demand customers when deploying XGS-PON. High-ARPU areas, such as business districts or high-end residential zones, are typically the first to benefit from this upgrade. As competition intensifies and bandwidth demand grows, Combo PON ensures that service providers can offer the best of both worlds: a reliable GPON service and an upgraded XGS-PON service for those who need it.
Conclusion
Combo PON is a powerful solution for telecom operators looking to upgrade their networks without the hassle of a full-scale replacement. By allowing GPON and XGS-PON to coexist, Combo PON offers a flexible, cost-effective way to introduce higher bandwidth services while maintaining network stability.
