40G Core Switch from a Swedish Manufacturer

Currently, there is no widely recognized Swedish manufacturer offering 40G core switches; leading options come from global vendors like Arista, Edgecore, FS, and Nivetti.

Global 40G Core Switch Options

• Arista Networks: Offers high-performance modular switches such as the 7800R4 and 7800R3 series, supporting up to 460 Tbps throughput, 400GbE/100GbE/40GbE ports, and advanced features like MACsec, EVPN-VXLAN, and programmable EOS software for cloud and data center environments . These switches are ideal for large-scale AI/ML clusters and universal spine deployments.
• Edgecore Networks: Provides 40G TOR (Top-of-Rack) and spine switches designed for hyperscale cloud operators, emphasizing scalability, reliability, and energy efficiency . Edgecore switches support high-density 40G QSFP+ ports and integrate with SDN and automation frameworks.
• FS (FS Deutschland): Offers L3 managed 40G switches such as the S8550-6Q2C (6 x 40Gb QSFP+, 2 x 100Gb QSFP28) and S8550-16Q8C (16 x 40Gb QSFP+, 8 x 100Gb QSFP28) with features like EVPN-VXLAN, MLAG, BGP, OSPF, MPLS, and MACsec . These switches are suitable for enterprise core networks and medium-scale data centers.
• Nivetti: Provides the NSP-32 40G/100G QSFP28 switch, a fully managed L3 switch with SDN capabilities, REST APIs, VxLAN, MLAG, ECMP, and dual hot-swap power/fan redundancy . It is designed for enterprise core layers and spine deployments in data centers with up to 1500+ servers.

Key Features to Consider

1. Port Density: Ensure the switch supports sufficient 40G QSFP+ ports for your network topology.
2. Layer 3 Capabilities: Look for BGP, OSPF, EVPN-VXLAN, and MPLS support for routing and virtualization.
3. Redundancy and High Availability: Dual hot-swap power supplies, fan redundancy, and MLAG/ECMP support are critical for mission-critical environments.
4. Programmability and SDN Support: REST APIs, EOS SDK, or NiOS enable automation and integration with modern orchestration tools.
5. Security: MACsec and other encryption features help secure data in transit.

Conclusion

While no Swedish manufacturer is currently highlighted for 40G core switches, several global vendors provide robust, enterprise-grade solutions suitable for core and spine deployments. If a Swedish-made switch is a strict requirement, it may be necessary to contact local distributors or smaller Nordic networking companies, as they may offer OEM or rebranded solutions. Otherwise, Arista, Edgecore, FS, and Nivetti represent reliable alternatives with proven performance and advanced features.
