Our mission
Reliable, affordable broadband is essential infrastructure. Building fiber that serves everyone takes more than capital and technology. It takes long-term thinking, collaboration and the right tools.
COS Systems exists to meet that challenge. We build software for open, scalable fiber networks that balance commercial viability with public value.
Our guiding goal has not changed since day one: bridge the digital divide and bring affordable FTTH to everyone, everywhere.
What we stand for
Our values come from our customers. We reviewed years of operator feedback and discussed it as one team, across Sweden and North America. Three values describe how we work, and each one shows up in real projects.
We stay with our customers for the long run and share responsibility for the result.
We go first on hard problems, so operators don’t carry that risk.
We share knowledge, experience and networks. Open access is sharing by design.
Our history
COS started with people who had spent years building and operating fiber networks. They saw the value of fiber, and the operational complexity behind it. Success depends on how networks are planned, operated, shared and sustained over decades. That insight became our mission.
Nearly two decades of building and operating fiber networks
certified in 2026, passed at first attempt
continents: customers in North America, Europe and Africa
business models supported directly: retail, open access and hybrid
We have worked with FTTH since the early rollouts of the 2000s. We have met the operational problems before, so you don’t face them alone.
COS builds BSS/OSS for FTTH and nothing else. Every workflow matches how fiber operators sell, provision and bill.
COS runs your business processes through configuration, not custom code. That shortens time to market. It supports retail, open access and hybrid models.

COS Systems delivers a cloud-based platform built for broadband operators, automating operations from demand generation through provisioning, billing, and field service. Operators run COS Business Engine as the operating core for retail, open access, or hybrid models, and add COS Wholesale Engine as the wholesale layer when several ISPs sell on the network. COS FSM, COS Prospector and COS Marketplace extend the portfolio across field service, door-to-door sales and the subscriber storefront, and COS Fiber Flow extends it with Active Ethernet network operations.
