Fiber optic Dark Fiber - Ufinet

Dark Fiber

We have an extensive fiber optic network deployed of more than 58,200 km in two continents: America and Europe.

One of the features that make us almost unique around the world is that we offer dark fiber, either in the form of rental of threads or in the mode of long-term transfer of rights to use through commercial agreements or IRU: Indefeasible Right of Use.

Our optical fiber cable network has a full infrastructure ready for customers who need to rent a single, a pair or more strands of fiber optic cable, either for small, medium or long-distance requests. This kind of service is more convenient for customers requiring a very high bandwidth connectivity. We provide the dark fiber cable and the customer illuminates it according to its needs and with its own equipment. Our laying of dark fiber has a permanent maintenance, in a preventive and routine approach, as well as in the face of a breakdown.


  • Monomode optical fiber – we use monomode fiber optic only, which sends information through a single high intensity light beam

  • Fiber connections with or without redundancy by an independent second way

  • Diverse contractual periods and rental modalities


  • Unlike multimode fiber, monomode optical fibers reach very large distances and transmit information without loss of packages

  • Personalized bilingual customer support 24×7 through our Network Operations Center (NOC)

  • Fulfillment of the most demanding SLA’s: Service Level Agreements of the market
