COS Systems and Calix Expand PON Networks in the Nordics
The Nordics have long been at the forefront of fibre rollouts, and while Active Ethernet has historically dominated the region, the global shift towards PON (Passive Optical Network) technology is gaining momentum. As a market leader in FTTH solutions across North America, Calix is now introducing its innovative PON solutions to the Nordics in collaboration with COS Systems, enabling operators to seamlessly modernise and scale their networks.
“The Nordics have always led the way in broadband innovation, and we’re excited to bring our cutting-edge PON technology to Sweden and beyond. Together with COS Systems, we are making it easier than ever for operators to deploy smarter, more sustainable fibre networks,” says Patricia Öien Ingemarsson, Sales Manager Nordics at Calix.
Why Calix PON?
Active Ethernet networks provide a dedicated fibre connection to each user, ensuring consistent bandwidth and high performance. However, they require energy-intensive switches distributed throughout the network footprint. PON, on the other hand, utilises a shared fibre infrastructure with optical splitters (mirrors) to distribute signals, making it more cost-efficient and less vulnerable.
While traditional concerns around PON have centred on potential bandwidth contention, advancements from industry leaders such as Calix now enable multi-gigabit speeds on XGS – PON, 50G Pon and beyond. Compared to Active Ethernet, PON technology from Calix delivers several key advantages:
- Lower energy consumption – A greener, more cost-efficient network
- Scalable capacity management – Seamlessly meets growing demand
- Optimised operations & maintenance – Automation streamlines network management
- Simplification – Easy and quick setup for fast roll-out
- IP/MPLS enabled platform, with integrated BNG capabilities
- Modular, Compact (1RU) High-density OLTs
A Seamless Transition with COS Systems and Calix
With a long-standing global partnership, Calix and COS Systems provide a fully integrated solution to support network owners and operators. COS Systems offers a comprehensive broadband management platform (BSS/OSS), ensuring a smooth, automated migration to PON.
The deep integration between COS Systems & SMx SDN Controller – an advanced network Manager with a REST based API and NetConfYANG configuration model enables:
- Automated provisioning – Simplifies service activation for new customers
- Network Sync & Registry – Ensures seamless operation and accurate element tracking
- 24/7 Monitoring & Diagnostics – Detects disruptions, analyses ONT status, and enables remote troubleshooting with real-time visibility into connected devices
With this integration, operators benefit from a scalable, automated solution that maximises efficiency, minimises downtime, and provides unparalleled flexibility.
“Our collaboration with Calix has been incredibly successful, and we’re thrilled to expand it further. By integrating our solutions, we empower operators with a seamless transition to PON, optimising everything from service activation to troubleshooting,” says Mikael Philipsson, CEO of COS Systems.
