FAQ
What switch size for my network?
Guideline: 1 port per workstation + 20% reserve + uplink ports. 50 workstations: 48-port switch with 2× 10G SFP+ uplinks. We advise you free of charge.
Fiber or copper — when is fiber worthwhile?
Fiber from approx. 100 m distance (copper limit) or when electromagnetic interference (EMC) is a problem. In data centers: fiber for backbone connections from 10G.
How do I plan a secure enterprise network?
Basic principle: segmentation (VLANs), access control (802.1X), firewall at perimeter, IDS/IPS internally, VPN for remote access. We support with planning.
