The company operates a 6,887 km network spread over seven fiber optics networks, covering the main cities in the country. At the same time, the network is integrated with microwave links, providing better redundancy and coverage in intermediate cities.

The company provides connection to Maya, Emergia, Panamericano, Arcos 1, Globenet and CFX undersea cables, having also a “carrier class” Internet access platform with direct connection to the most important suppliers in the USA.

This network consolidates Colombia as INTERNEXA most important market, taking into account the number of customers and revenues, and the second most important considering network length.
