Service providers almost always install more fiber strands than necessary to ensure the future security of fiber optic networks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dark fiber is simply disconnected optical fibers through which no light waves run and therefore no data is transmitted. Even though dark fiber is available for large corporations, municipalities and small to medium-sized companies, it is often not necessarily the right choice.<\/p>\n\n\n\n<h3 id=\"h-the-advantages-of-dark-fiber\" class=\"wp-block-heading\" style=\"margin-top:var(--wp--preset--spacing--40);margin-bottom:var(--wp--preset--spacing--20)\">The advantages of Dark Fiber<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Depending on your needs, there are many potential benefits to using dark fiber. However, for most companies and organizations, 4 of them are particularly important.<\/p>\n\n\n\n<h4 id=\"h-control\" class=\"wp-block-heading\">Control<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Leased dark fiber can be separated from a service provider&#8217;s general network so that a business or facility has complete control over what runs through its internal <a href=\"https:\/\/www.savecall.de\/en\/glass-fiber\/\">fiber network<\/a>.<\/p>\n\n\n\n<ul class=\"wp-block-list savecall-list big arrow-blue small\">\n<li>Possibility to improve latency times<\/li>\n\n\n\n<li>Customers can make changes to the network at their own discretion<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">High performance<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to Dense Wavelength Division Multiplexing, Dark Fiber can deliver super-fast speeds. By using different wavelengths, multiple signals can be transmitted simultaneously over the same fiber strand. Dark Fiber also requires less power than standards such as copper and cable. Data is transmitted from point to point in a straight line, which makes dark fiber less sensitive to signal interference.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An example from practice:<\/p>\n\n\n\n<ul class=\"wp-block-list savecall-list big arrow-blue small\">\n<li>Connection of two data centers via a point-to-point segment<\/li>\n\n\n\n<li>Improvements in bandwidth, stability, latency and security<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2000\" height=\"719\" src=\"https:\/\/www.savecall.de\/wp-content\/uploads\/2025\/09\/autobahn-1-min-neu-klein-min.png\" alt=\"Underground fiber optic cables visualized as glowing data streams next to a city highway at night, a symbol for high-speed Internet and dark fiber solutions from SAVECALL.\" class=\"wp-image-2680\" srcset=\"https:\/\/www.savecall.de\/wp-content\/uploads\/2025\/09\/autobahn-1-min-neu-klein-min.png 2000w, https:\/\/www.savecall.de\/wp-content\/uploads\/2025\/09\/autobahn-1-min-neu-klein-min-300x108.png 300w, https:\/\/www.savecall.de\/wp-content\/uploads\/2025\/09\/autobahn-1-min-neu-klein-min-1024x368.png 1024w, https:\/\/www.savecall.de\/wp-content\/uploads\/2025\/09\/autobahn-1-min-neu-klein-min-768x276.png 768w, https:\/\/www.savecall.de\/wp-content\/uploads\/2025\/09\/autobahn-1-min-neu-klein-min-1536x552.png 1536w\" sizes=\"auto, (max-width: 2000px) 100vw, 2000px\" \/><\/figure>\n\n\n\n<h4 id=\"h-security\" class=\"wp-block-heading\">Security<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">With its <a href=\"https:\/\/www.savecall.de\/en\/point-to-point-connection\/\">point-to-point connections<\/a>, a <a href=\"https:\/\/www.savecall.de\/en\/dark-fiber\/\">dark fiber network<\/a> never enters the realm of the public Internet. In fact, the network is not even shared with third parties. Dark Fiber is a dedicated line that can be self-managed, with a company in control of its own light generation equipment.

However, despite its potential, it is difficult to access in many areas. Providers do not usually sell dark fiber directly to SMEs, but rather to public authorities or network operators.

In rural regions or less densely populated areas, dark fiber often remains an inaccessible service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The alternatives offered by the respective providers are solutions that are based on the OSI model between layers 1 and 2.

No light waves run through these disconnected fibers, so no data is transmitted. Service providers almost always install more fiber strands than necessary to future-proof their networks. Dark fiber is available to large corporations, municipalities and small to medium-sized companies, but it is not always the right choice.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784900102202\"><strong class=\"schema-faq-question\">What are the advantages of Dark Fiber?<\/strong> <p class=\"schema-faq-answer\">Dark fiber offers full control over your own fiber network, very high performance thanks to Dense Wavelength Division Multiplexing, and increased security, since the network never enters the public Internet and is not shared with third parties. It also scales flexibly: a single cable can be divided into up to 80 channels and grows in sync with company development.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784900103303\"><strong class=\"schema-faq-question\">What are the disadvantages of Dark Fiber?<\/strong> <p class=\"schema-faq-answer\">Full control also means full responsibility: integration, maintenance, repair and permanent monitoring rest with the company itself, often requiring additional IT staff. Availability is also limited, many lines are already occupied or simply do not exist in rural areas, which drives up costs. Fiber optic cables themselves are expensive, and economic efficiency depends heavily on distance.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784900104404\"><strong class=\"schema-faq-question\">What alternative exists if Dark Fiber is not available?<\/strong> <p class=\"schema-faq-answer\">Since providers usually do not sell dark fiber directly to SMEs and the technology is often only available in large conurbations, EthernetConnect 10G Flex and 100G Flex is a nationwide alternative in Germany. It is a point-to-point connection based on the OSI model between layer 1 and 2, where bandwidth can be divided across different interfaces.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784900105505\"><strong class=\"schema-faq-question\">How secure is EthernetConnect as an alternative to Dark Fiber?<\/strong> <p class=\"schema-faq-answer\">EthernetConnect uses layer 1 encryption with AES256 based on the latest cryptographic standards. Encryption is performed with low latency when mapping the Ethernet signal into the optical transport container, and the session key is exchanged via Diffie-Hellman-Merkle key exchange, periodically renewed and known only to the secured hardware. Proactive fault management additionally ensures that faults are detected and reported within 10 minutes.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1784900106606\"><strong class=\"schema-faq-question\">How does SAVECALL support the decision between Dark Fiber and alternatives?<\/strong> <p class=\"schema-faq-answer\">SAVECALL checks vendor-neutral whether dark fiber is available and economically viable at your location, and compares the costs with alternatives such as EthernetConnect or SD-WAN-based solutions. We obtain vendor-neutral offers and support you from requirements analysis through to implementation, so your site connectivity fits your budget and requirements.<\/p> <\/div> <\/div>\n\n\n\n<div
