Our Services

ZenFi Networks provides the most effective, scalable, and secure high speed fiber network solutions to meet the demands of today’s businesses. Implementing custom connectivity solutions comes as a direct result of working with clients to understand and support their requirements.

Dark Fiber

The base layer of all high speed data networks is Dark Fiber. ZenFi Networks began deploying new network in 2012 and has amassed hundreds of route miles of new Single Mode fiber that meets or exceeds the standards set in ITU-G.652D. By utilizing the most advanced deployment techniques and fusion splicing technology. ZenFi Networks plant is not plagued with added loss due to over-splicing or legacy splicing techniques. The outcome is an optical network providing the lowest possible dB loss in respect to fiber distance. Our comprehensive approach to service design and implementation concentrates on delivering a best in class Dark Fiber product capable of supporting applications from 1G optical all the way to 100G DWDM with up to 17.6 Tb of throughput. Solutions vary from off the shelf standard fiber products to completely custom network designs, ZenFi Networks can tailor a network to each customer’s unique needs. Post deployment, Cross River ensures the customer maintenance and restoration events are resolved in a timely manner with as little customer impact as possible.
