The Future of MicroTechnology today

Please download our MicroTechnology Product Guide and FTTX System Catalogue.

MicroTechnology is a forward-thinking, future-oriented technology that you can put in place today. As network demands continue to grow, it becomes more important than ever to better utilize the available space in your existing ducts systems.

Single Microducts or bundles like DuraMulti, DuraFlat or DuraPack allow for controlled expansion of your network, meeting bandwith requirements as needed. With the multiple pathways in bundle, as your network grows, you will have available pathways without additional construction costs.

With MicroTechnology, the ability to remove the cable for upgrades or repairs as needed is possible without incurring additional constructions costs.

Using MicroDucts from Dura-Line is a better way to utilize that empty space, both today and tomorrow. It allows you to expand your fiber network as you bring on new customers. It enables you to increase bandwidth as your needs increase. And, it allows you to do it easily, without adding extra fibers that might never be used.

MicroTechnology saves you time and money, allowing for economical growth within your communications network. Using microducts is the most economical way possible to build your network.

Installing multiple MicroDucts at one time enables you to use your duct system to its fullest. Installations are quick and easy when you use the latest air-jetting equipment. We can deliver MicroDucts factory preinstalled in ducts, or on individual reels for installation in new or existing duct systems.

With MicroTechnology from Dura-Line, you can save on future construction costs by thinking about the future today. Applications are vast and the markets we serve are some of the world’s most rapidly expanding industries:Telecom, CATV and Power Utilities. These industries demand versatility as technologies and innovations are changing every day.

Single MicroDucts are products used in microtrenching i.e. saw-cut micro routes in asphalt and concrete, cost effective especially in high density, metropolitan networks.
