After learning the last week’s blog post about submarine cables, we know that as of 2014, there are 285 communications cables at the bottom of the ocean, and 22 of them are not yet in use. And these un-used cables are called “dark cables” or “dark fiber” for fiber cable (we will mainly talk about dark fiber in this paper). In fact, except the un-used submarine fiber cables, all the optical fibers that have been laid but is not currently being used in fiber-optic communications are called dark fiber.
As bandwidth requirements continue to climb, increasing demands will be placed on optical fiber. In order to save money and meet the increasing demands on bandwidth, companies and institutions are turning their attention to the secure and private “dark fiber” network. By leasing segments of a dark fiber network, businesses can use their own IT staff and networking equipment to connect their multiple locations to create a private network or to connect to other network hubs to gain access to various high speed internet providers.
The following infographic provides a visual explanation of dark fiber and how it can help institutions maintain the fastest transmission speeds, as well as save money by scaling the amount of bandwidth purchased to more closely match a business’s specific requirements, while preserving an unlimited potential for growth.
