Design & price my architecture →What is it?
Dark fiber is optical fiber rented 'unlit' by the carrier: you install your own equipment (transponders, WDM/DWDM) and get private, scalable, independent capacity.
Business benefits
- Uncapped bandwidth: go from 10G to 100G+ by changing only your optics.
- Minimal, deterministic latency (dedicated path, no sharing).
- Confidentiality: your traffic is not mutualized with other customers.
- Decreasing cost over time for large inter-site volumes.
Enterprise use cases
- DR/BC interconnection between two data centers with storage-array replication.
- Multi-building campus of a large enterprise or healthcare organization.
- Carrier/integrator building its own regional backhaul.
FAQ
Dark fiber vs managed Ethernet link?
A managed Ethernet link is lit and operated by the carrier (defined bandwidth, SLA included); dark fiber is yours to light and has no bandwidth cap, but requires your own equipment.
Is dark fiber available everywhere?
No: it depends on existing infrastructure along the route. Eligibility and lead time are confirmed at quote with fiber carriers.
What equipment lights it?
Transponders, and a WDM/DWDM system to multiply channels. Sizing depends on target bandwidth and distance.
