Conterra Ultra Broadband, a provider of broadband transport services, has secured $41 million in new financing.

DukeNet Communications, a subsidiary of Duke Energy, participated in the round.

The other investor was not identified other than Conterra describing the firm as a “leading investment management firm with more than $13 billion of assets.”

Last September, Conterra landed an undisclosed investment from DukeNet and GE Commercial Finance. DukeNet also entered into an alliance with DukeNet.

The latest funds will be used for further expansion of Conterra’s networks, the company said. Conterra delivers services over fiber and microwave networks.

Conterra’s network provides service in 11 states.

"This financing, provided by such deeply resourced institutional and strategic investors, will support the growing backlog of orders for our wide area and backhaul network service deployments to schools, businesses and wireless carriers throughout the country," said Stephen Leeolou, chairman and chief executive officer of Conterra.

Conterra focuses on suburban and rural markets.
