It can be a great solution, but it\u2019s not right for every circumstance. Here are some facts and considerations when considering building a dark fiber network.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">1. What is dark fiber?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">\u00ab<\/span><a href=\"https:\/\/www.datacenterdynamics.com\/en\/analysis\/what-is-dark-fiber\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Dark fiber<\/span><\/a><span style=\"font-weight: 400;\">\u201d refers to unused fiber optical cables. These cables are installed, configured, and ready to use, but they\u2019re not yet connected to anything. They will remain \u201cdark\u201d until they\u2019re connected to electronic equipment and \u201clit\u201d (activated) for transmissions.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">2. Why do data centers use dark fiber?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Dark fiber is often kept in reserve so data centers can expand their networks quickly. Rather than installing new cables each time bandwidth demand grows, data centers can install many fibers simultaneously and then switch them on as needed.\u00a0<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">3. What are the most common applications of dark fiber in data centers?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">There are several reasons a data center might choose to use dark fiber, but these are the main ones:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Cloud services<\/b><span style=\"font-weight: 400;\"> &#8211; Cloud services have peaks and valleys of usage during different times of the year. Data centers with dark fiber on standby can activate them during periods of high demand.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Interconnecting facilities<\/b><span style=\"font-weight: 400;\"> &#8211; Dark fiber can create high-speed networks that connect multiple locations for fast communication and data transfer.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Edge computing<\/b><span style=\"font-weight: 400;\"> &#8211; For edge nodes to communicate seamlessly, they must have a means of rapid and reliable data transfer. Dark fiber is a great way to accomplish this.\u00a0<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">4. What\u2019s the advantage of keeping dark fiber on hand?<\/span><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Cost efficiency and scalability<\/b><span style=\"font-weight: 400;\"> &#8211; If a data center wants to increase bandwidth, it usually has two options: either purchase and install new fiber optic cables for each expansion or lease extra bandwidth from network providers.<\/span>Frequent installations of network cables are costly, and they can disrupt service for a time. Leasing extra bandwidth can also be expensive, especially if the expansion is permanent.Dark fiber offers a less expensive way for data centers to expand bandwidth as demand grows.<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Control<\/b><span style=\"font-weight: 400;\"> &#8211; Dark fiber is controlled by the data center rather than the service provider, meaning the data center can choose its equipment and activate or deactivate cables as needed.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>\u0411\u0435\u0437\u043e\u043f\u0430\u0441\u043d\u043e\u0441\u0442\u044c<\/b><span style=\"font-weight: 400;\"> &#8211; Since dark fiber doesn&#8217;t actively transmit data, it\u2019s more difficult for unauthorized users to find and tap into live connections. Additionally, data centers have full control over their cable infrastructure, which makes it more difficult for potential hackers to tamper with equipment.\u00a0<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">5. Which industries often use dark fiber?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Some industries have stronger use cases for dark fiber than others. The following are especially suited for using dark fiber.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>High-bandwidth industries<\/b><span style=\"font-weight: 400;\"> &#8211; Cloud computing platforms and generalized data centers both tend to regularly encounter increased demand for bandwidth.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>High-security industries<\/b><span style=\"font-weight: 400;\"> &#8211; Dark fiber networks are privately owned and operated on the grounds of the data center, so they are great for sensitive industries such as healthcare, defense, and financial services. Private fiber connections are far more difficult to intercept than the typical shared, commercial internet service.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Businesses requiring low latency<\/b><span style=\"font-weight: 400;\"> &#8211; When circumstances call for fast data transmission\u2014think financial trading platforms, online games, and real-time data processors\u2014dark fiber is a wonderful choice. Data centers can optimize connections for rapid transfer speeds and minimal latency.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Large-scale retailers and e-commerce businesses<\/b><span style=\"font-weight: 400;\"> &#8211; Retailers can use dark fiber to maintain fast and secure connections between their network of warehouses, distribution centers, retail locations, and central offices.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Government and educational institutions<\/b><span style=\"font-weight: 400;\"> &#8211; These organizations often require fast, secure, private, and extensive networks to perform optimally. This makes dark fiber a superior solution to commercial internet connections.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Critical industries that need physical redundancy<\/b><span style=\"font-weight: 400;\"> &#8211; Disaster recovery is crucial for some organizations, including healthcare facilities, financial institutions, and any companies that provide critical infrastructure or services that can\u2019t be interrupted.<\/span>Dark fiber offers these organizations a physical network that could be used as a backup if the primary system ever goes down.<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Organizations that use edge computing<\/b><span style=\"font-weight: 400;\"> &#8211; As edge computing becomes more popular, the demand for low-latency data transfers between multiple nodes grows proportionally. Smart city initiatives, IoT, and autonomous vehicle systems are a few examples of industries where dark fiber shines.\u00a0<\/span><\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">6. What are the challenges of using dark fiber?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">While dark fiber can be an excellent choice, it\u2019s a solution with some challenges.\u00a0<\/span><\/p>\n<ul>\n<li><b>Cost<\/b><span style=\"font-weight: 400;\"> &#8211; Installing dark fiber requires a considerable up-front cost. <\/span>Most data centers need to lease fiber optic cables rather than purchasing them outright. They will also need to purchase and install equipment to connect to both ends of the fiber cables.If the data center never ends up activating those fibers and they lie dormant, the ROI may never be realized.<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Maintenance<\/b><span style=\"font-weight: 400;\"> &#8211; Since data centers control their fiber networks, there is no ISP to dispatch technicians to keep the network in good condition. This means maintenance tasks and costs all fall on the data center.<\/span>This can be troublesome for smaller facilities without a lot of experience or resources because fiber optic cable installation and maintenance require some technical expertise and training.<\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Limited availability<\/b><span style=\"font-weight: 400;\"> &#8211; Facilities in rural areas\u2014especially in remote locations\u2014will have fewer options for installing a dark fiber network.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Bureaucracy<\/b><span style=\"font-weight: 400;\"> &#8211; Getting a fiber network approved may require the permission of multiple entities, including service providers and governmental permit agencies. Navigating this labyrinth can be costly and time-consuming.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Complex design and engineering processes<\/b><span style=\"font-weight: 400;\"> &#8211; Putting together an efficient dark fiber network isn\u2019t a simple task. Designers and engineers may have to contend with overlapping networks, physically separate pathways, rocky or otherwise difficult terrain, and the prospect of building redundancy and diversity in cable routes.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Limitations in scalability<\/b><span style=\"font-weight: 400;\"> &#8211; Because scalability is often a major point of dark fiber networks, it might seem counterintuitive to think that dark fiber itself can constrain scalability.<\/span>However, the goal of dark fiber is that a data center pays for a large cable installation once\u2014and should be able to go a long time before needing to install more. This means that the ultimate\u00a0 \u00a0 scalability of an organization&#8217;s network comes down to how the original project was planned and implemented. Adding onto the infrastructure down the line if further capacity is needed defeats the purpose and can increase costs and downtime.<\/li>\n<\/ul>\n<h3><span style=\"font-weight: 400;\">7. What is the future potential for dark fiber?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Despite the above-mentioned challenges, dark fiber helps to future-proof a data center. Data centers almost <\/span><i><span style=\"font-weight: 400;\">always <\/span><\/i><span style=\"font-weight: 400;\">encounter periods of rapid growth due to newly emerging technologies such as AI, quantum computing, and IoT, and they\u2019ll almost certainly experience the same type of challenges from technologies that haven\u2019t hit the mainstream yet. In the data center industry, expansion is just part of the job.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Laying some extra cables in the form of dark fiber means data centers can plan ahead of demand surges and rise to the occasion in a quick and relatively cost-effective manner.\u00a0<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>","protected":false},"excerpt":{"rendered":"<p>Considering dark fiber for your data center?
