Installing fiber optic cable can be an expensive and lengthy process. Often, it requires an extended period of right-of-way negotiations and acquisitions before a company starts to dig. Plus, there’s a costly and disruptive construction process that must take place before the lines are secure and buried.
A common practice with fiber is to bury excessive cables while field crews are already underground, so that they won’t have to dig again. Over the years, many companies installing fiber have adopted this process.
This blog post will explain dark fiber in detail—discussing 3 advantages and 3 disadvantages. It will also look into what the future holds for dark fiber.
What is Dark Fiber?
But because of fiber’s high capacity, the common definition of dark fiber has been stretched in recent years to include fiber infrastructure that may already be under lease, but has capacity to accommodate additional users.
A technology known as dense wavelength division multiplexing (DWDM) permits multiple users to transmit through a single fiber cable, without the signals interfering with one another. Depending on various needs, one fiber optic cable can serve several users at a time.
Perhaps the most important word in an explanation of dark fiber is potential. Dark fiber is dormant, but it’s right there beneath the surface, ready to be used. Some companies that own a lot of dark fiber have decided they might as well be making money on it, so they rent it to other companies that need the bandwidth.
3 Advantages of Dark Fiber
1. It’s Appealing
2. It’s Economical
3. It’s Controllable
3 Disadvantages of Dark Fiber
1. Lack of Availability

Dark Fiber Checklist
Has the fiber’s owner done a recent cable test? Are the results available? Not all dark fiber is created equal. A test can pinpoint signal loss and capacity issues.
Find Alternate Routes
It’s good to have an alternate data path to keep traffic moving in case a problem arises with the primary fiber in use.
An optical-network monitoring system can spot potential problems in the network before they become major issues.
What Does Dark Fiber Mean for Joint Use?
