Coenen began by explaining that the term “dark fiber” refers to fiber optic cable that has been laid in the ground but isn’t being used. “Whenever somebody buries a fiberoptic cable, most of the cost is in getting that cable into the ground,” explained Coenen. “Something like less than 10 percent of the cost of such a project is actually the fiberoptic cable. So, what they do is bury as many actual fibers as possible.” In many cases, less than half of the actual cables underground are being used, leaving the rest available for companies to lease.
So why would an enterprise be interested in leasing this dark fiber?
- It’s all about the money.
- Dark fiber can also improve latency.
- Dark fiber can provide redundancy.
- Dark fiber does require some expertise.
- You shouldn’t be afraid of dark fiber.
