Looking for the best Dark Fiber providers in San Jose in California, United States? Here's your ultimate guide to making an informed choice.
What is Dark Fiber?
Dark Fiber refers to unused fiber-optic cables that are available for lease or purchase. These cables, also known as 'unlit fiber,' require the lessee to install and maintain the necessary electronics to make them operational, offering full control over network architecture, speed, and security.
Dark Fiber providers are highly dependent on geographic location due to the necessity of existing network infrastructure. The availability of these services is typically greater in major cities and along primary fiber lines, making it challenging to access in rural or remote areas.
