Dark fiber also known as Unlit Fiber or Black fiber, and is used commonly in Telecom and Network Communications. For businesses and companies, owning and operating their own fiber-optic network tends to be more economical. Organizations gain benefits such as network speed and autonomy over their network when dark fiber is utilized. often times businesses find their growth to be alarmingly quick, which can cause issues with their bandwidth being at capacity. This prevents businesses from running efficiently and effectively.
