Level 3 Communications announced that it is providing the Library of Congress with fiber optic links that will transport more than 1 million theatrical films, newsreels and television programs for the world’s largest library.

The carrier’s Wholesale Markets Group says this deal represents a “multiyear” contract, but Level 3 would not provide details on the length or financial terms of the deal.

Level 3 has deployed connectivity that extends the Library’s Dense Wavelength Division Multiplexing (DWDM) network, the carrier says. This connectivity will specifically be used to support the Library’s National Audio Visual Conservation Center (NAVCC).

The NAVCC is scheduled to open mid-year and will support the Library’s vast amounts of audio visual content, including early voice recordings of historical figures and 3 million commercial sound recordings.

Level 3 was also named as one of the five Networx Enterprise contract winners last month. AT&T, Qwest, Sprint Nextel and Verizon were the other winners. All five will be competing to win business with hundreds of government agencies.

Networx Enterprise is part of the General Services Administration’s 10-year, multibillion dollar telecom contract. The first part of the contract, called Networx Universal, was awarded in March to AT&T, Verizon and Qwest.
