What Ssga does

SSGA (Stichting Samenwerkingsverband Glasvezelnetwerk Arnhem) is a Dutch non-profit foundation established in 2002 that provides managed dark fiber connectivity exclusively to non-profit organizations in the Arnhem region of the Netherlands. Founded by SURFnet, Gemeente Arnhem, and ROC Rijn IJssel to share costs of building common fiber infrastructure, SSGA operates as a cooperative where participants become co-owners of the network and benefit from proportional cost-sharing with trekkingsrechten (withdrawal rights) that redistribute contributions as new members join. The network has grown from 3 founding partners to over 25 participants across education, healthcare, municipalities, and cultural institutions.

The core infrastructure is a redundant ring topology comprising two main rings in Arnhem (North and South) plus two regional rings (Veluwezoom and Liemers), with interconnection to Nijmegen via TeleMANN. Cable bundles contain 96 fiber strands, with each participant receiving at least one fiber pair capable of 10 Gbit/s, expandable via Wavelength Division Multiplexing (WDM). SSGA maintains the passive infrastructure while participants deploy their own active equipment, and Spie operates the NOC for incident management. The network is 'besloten' (closed), limiting use to participants' own organizational needs and excluding SSGA from acting as an open infrastructure provider.

The revenue model combines one-time connection fees, proportional shared infrastructure contributions (decreasing per participant as the network grows), and annual management/maintenance fees allocated by formula. GTM is community-led and sales-led through direct personal outreach, information sessions, and referrals from existing participants. Marketing is consultative, with the website serving as an educational FAQ resource. The headcount is approximately 5 management staff (Manager, Project Manager, Office Manager), with governance through an Algemeen Bestuur and Dagelijks Bestuur comprising representatives from participant organizations. Revenue figures are not publicly disclosed.

Revenue model

1. Membership/Participation Contributions: Organizations join the foundation and contribute proportionally to the shared common infrastructure. New participants pay an equitable share to existing participants based on the shared cost model.
2. Annual Management and Maintenance Fees: Annual costs for management and maintenance of the fiber network are distributed among participants using a allocation formula. Costs per participant decrease as more participants join.
3. One-time Connection Fees: New participants pay one-time costs for connections between their locations and the city ring. These costs vary significantly and are quoted by contractors.

Core offering

SSGA operates a regional, redundant fiber optic ring network (the Stadsring) that delivers managed dark fiber connectivity exclusively to non-profit organizations in the Arnhem region. Participants receive dedicated fiber pairs that they light with their own active equipment, while SSGA maintains the passive infrastructure. The foundation handles enrollment, shared infrastructure cost allocation, one-time connection provisioning, and ongoing management and maintenance of the passive network.

Product overview

SSGA is a non-profit fiber optic infrastructure foundation providing managed dark fiber connectivity to non-profit organizations in the Arnhem region. Their primary offering is the 'Stadsring' (city ring) network—a redundant ring-based fiber infrastructure spanning over 25 participants. The foundation offers managed dark fiber where participants receive physical fiber pairs and deploy their own active equipment, with SSGA maintaining the passive infrastructure. The network operates as a 'closed' network exclusively for participants' own use. Additional services include regional interconnection through TeleMANN to Nijmegen and NOC support via Spie for incident management.

Functional benefit

Products and services

• Managed Dark Fiber SSGA's primary offering: managed 'unlit' (dark) fiber optic pairs delivered over the regional ring network. Participants receive physical fiber pairs and SSGA maintains the passive infrastructure; participants deploy their own active equipment to 'light' the fibers, giving them full control over their network configuration.
• Stadsring Glasvezelnetwerk (City Ring Network) The core fiber optic ring infrastructure connecting participant locations. The network comprises two main rings in Arnhem (North and South) plus two regional rings (Veluwezoom and Liemers), providing redundant connectivity for non-profit organizations across the Arnhem region.
• TeleMANN Network Interconnection Partnership-based interconnection providing SSGA participants with extended network reach from the Liemers branch and Arnhem South ring to Nijmegen, via the TeleMANN network.
• Network Operations Center (NOC) Support Incident reporting and network operations support provided through Spie's NOC. Participants can report fiber network outages directly via email ([email protected]) or phone (088 3131 099).
