Colt Technology Services today launched its U.S. network, connecting 13 cities in North America, including New York, San Francisco, and Chicago, to Colt’s Asian and European metro networks.

Colt services now available in the U.S. include enterprise bandwidth up to 100 Gb/s delivered over entire wavelengths and Ethernet. Colt also offers private network options and a number of wholesale services.

The company’s Asian and European networks comprise more than 870 data centers and 26,000 fiber-connected buildings that are controlled with the Colt IQ Network. With the IQ Network software technology enterprises are able to immediately boost bandwidth or quickly provision services at new locations.

Colt’s on-demand bandwidth provisioning is available to businesses in Europe and Asia with the service launching in the fourth quarter in the United States.

Colt began 25 years ago as a challenger to the local incumbents in London. “Today, we are a global network challenger that thinks and acts differently in a rapidly consolidating U.S. market,” said Colt CEO Carl Grivner in a statement. “We’re privately held, affiliated with Fidelity Investments, and have the freedom to act extremely rapidly in a market characterized by unique, on-demand requirements.”

Colt counts among its customers more than 650 financial businesses in Europe, Asia, and North America. It provides these customers with its Colt PrizmNet, a financial extranet connecting a global ecosystem of market participants to more than 120 exchanges, venues, clouds, and service providers. For example, Colt PrizmNet connects to the likes of Nasdaq, Amazon Web Services (AWS), and Trading Technologies.

Earlier this year, Colt worked with Verizon to demonstrate two-way orchestration of each other’s network using SDN.
