More About Stokab
Stokab operates as a passive infrastructure provider focused on dark fiber (network infrastructure) in the Stockholm region, supplying the physical layer that telecom operators, IT service providers, enterprises, and public-sector institutions use to build their own networks and services. The company’s model is based on structural separation between infrastructure ownership and service provision, where Stokab owns and manages the fiber network and customers light the fiber with their own active equipment.
The network is an open-access metropolitan area fiber infrastructure (metro fiber) laid out across Stockholm, including business districts, residential areas, industrial sites, and municipal facilities. It connects properties, data centers, and other nodes, enabling layer-1 connectivity for a range of higher-level services such as internet access, VPNs, mobile backhaul, and data center interconnects. Enterprises and institutions typically lease dedicated fiber pairs, gaining control over capacity, routing, and security at the optical level.
Stokab’s offerings align with standard fiber-optic network architectures based on Single-Mode Fiber (SMF) and support common telecom and data center transmission technologies, including Ethernet, IP/MPLS, and optical transport systems (network transport). Because Stokab provides passive fiber only, customers use their own active equipment such as switches, routers, and Dense Wavelength Division Multiplexing (DWDM) systems that comply with established telecom and data networking protocols. This architecture suits organizations that require high bandwidth, low latency, and predictable network behavior under their own operational policies.
The company serves both commercial operators and public-sector organizations, including municipalities, regional authorities, and state agencies, which use the network for communication between offices, schools, health facilities, and other sites (public-sector connectivity). For mobile operators, Stokab’s fiber is used for macro base station backhaul, small cells, and other Radio Access Network (RAN) connections, fitting into standard mobile network architectures where fiber links connect radio sites to core networks.
Within an enterprise IT and infrastructure directory, Stokab can be categorized under dark fiber and passive network infrastructure services, metropolitan fiber networks, wholesale connectivity, and smart city communication infrastructure. Its role is to provide a long-lived physical layer asset that underpins higher-layer services delivered by operators and IT providers, giving enterprises and institutions an option to separate infrastructure from service contracts and to design network topologies that fit internal requirements for capacity, redundancy, and governance.
