Integra Telecom (News - Alert) has announced the expansion of some of the company’s important metropolitan areas of the western U.S.

To provide wholesale, enterprise and carrier-class high bandwidth products and services, this expansion is part of Integra’s $52 million year-long plan to leverage its fiber network. Integra already operates the most extensive fiber network of any competitive services provider for business in the West. Integra’s fiber network consists of 5,000 long haul route miles and 3,000 metropolitan route miles, in addition to more than 1,600 lit fiber-fed buildings, the company stated in a press release.

Integra Telecom owns and operates its own network offering local dial tone, domestic and international long distance, high-speed Internet and data services (including digital subscriber line or DSL), voice messaging, and numerous ancillary services designed to support the communication needs of businesses including business phone systems.

“Integra has grown by providing service to thousands of small-to-medium sized business customers,” said Steve Zimba (News - Alert), chief marketing officer of Integra Telecom, in a company press release. “Now we are aggressively augmenting our world-class fiber network in order to serve demanding, high-bandwidth customers such as data centers, regional headquarters and multi-tenant business parks.”

To deliver a broad range of carrier Ethernet layer 2 and MPLS layer 3 services, Integra leverages its fiber capacity. The additional buildings on the fiber network are primarily located in the metropolitan areas of Seattle, Phoenix, Portland, Salt Lake City, Boise, Sacramento, and Spokane. To support the needs of enterprise-level customers that demand sophisticated, high-capacity, fiber-based solutions, the push to expand its network and increase the number of fiber-fed buildings is part of Integra’s approach.

Recently, the company announced that it has been selected by the Spokane Public Facilities District as the entity’s telecom provider. As per the agreement, Integra Telecom will provide phone and high-speed Internet services to the district’s three facilities including the Spokane Veterans Memorial Arena, the Spokane Convention Center and the INB Performing Arts Center. The contract enables Integra to become the ballroom sponsor at the Spokane Convention Center.
