Increasing demand for bandwidth means more funding and growth for Overture.

The Morrisville-based company, a provider of technology and services for Ethernet-based broadband worldwide, is adding new offices after securing $8 million new equity financing.

Overture, which is privately held, did not disclose the source of the funding.

However, the venture capital-backed firm said it also had an “opportunity” to raise as much as $11.7 million.

With the funds, Overture is opening two additional development centers beyond its Morrisville operation. The new offices are in Westford, Mass., and Bangalore, India.

Staff is now being hired, Overture said.

The company also plans to develop additional software, hardware and service offerings.

“Our industry is changing rapidly around advancements in software-defined and virtualized network services, initiatives that will enable us to advance Overture’s market leadership position in Carrier Ethernet,” Overture Chief Executive Officer Mike Aquino said in a statement.

“We are committed to providing our customers a competitive edge through the optimization of their service creation, activation and assurance.,” he added. “We are encouraged by the endorsement of industry analysts and customers around our direction. We are further energized by the investor commitment this funding represents. It will allow us to drive innovation to help service providers deliver a winning customer experience to their end users.”

Aquino joined Overture as its CEO last September. Aquino, a former executive at Ciena, has more than 30 years of experience in the communications industry

Overture technology is used by five of the world’s seven largest Carrier Ethernet service providers and eight of the 10 leading Ethernet providers in the U.S. 

Previous investors include Intersouth Partners, which is based in Durham.

In 2011, Overture merged with one of its Ethernet competitors, Hatteras Networks, which also was based in the Triangle.

Overture disclosed raising $17.2 million in 2010.
