If you’re in charge of your organization’s IT network, you
may have considered whether switching from a commercial internet services
provider (ISP) to a dark fiber network could improve performance and lower
costs. Or maybe you’ve heard of dark fiber networks but aren’t clear on the
value they might add or whether they’re a viable alternative for your
situation. Here, I’ll offer an overview of what dark fiber networks are and how
they work, along with eight optimal use cases for these networks.

Here, I’ll offer an overview of what dark fiber networks are
and how they work, along with eight optimal use cases for these networks.
Dark fiber network use cases
This is by no means an exhaustive list of scenarios where
dark fiber networks can be useful, but I’ve found that it’s often easier to
communicate the benefits of these networks by offering examples. So here are
eight common scenarios where a network might benefit from dark fiber.
1. Your bandwidth needs have increased significantly (beyond 1 Gbps) and are likely to continue to do so.
2. You have plans to significantly grow or scale your business and want to future-proof your network.
3. You want to expand an existing network or build a new one between geographically separated buildings.
4. Your budget allows for purchasing termination equipment at both ends of the network.
5. You want a network that is private, customized, or has extremely low latency.
6. You want a highly secure network.
7. You’re in an area where fiber-optic cables are already laid.
