JDSU introduces 450-mW pump laser

MAY 4, 2009 -- The 5100 Series supports more wavelengths or higher data rates for undersea networks.

MAY 4, 2009 -- JDSU (search Lightwave for JDSU) has announced availability of the 450-mW 5100 Series pump laser, which the company claims is the highest-power 980-nm pump laser available to the undersea optical networking industry. The 5100 Series will power undersea optical amplifiers that are needed to transmit fiber-optic signals along cables that span thousands of kilometers along the ocean floor, acting as critical transcontinental links for broadband communications. The new pump is intended to help network equipment manufacturers (NEMs) and service providers design higher-bandwidth undersea networks that can support more wavelengths or higher data rates.

The 5100 Series leverages the company's terrestrial pump-laser package for undersea deployment, which the company says has achieved 12 billion field hours with a failure in time (FIT) rate of 2.2.

The 5100 Series broadens JDSU's existing portfolio of undersea isolators and PIN detectors manufactured in Shenzhen, China. All three fiber-optic components share a common undersea manufacturing infrastructure with a low fixed cost. Each component is based on a terrestrial design that is also manufactured in high volume on site.

"With more than 600,000 terrestrial pump devices deployed since 2000, JDSU's customers can take comfort knowing that the 5100 Series is based on an extremely reliable and proven design," says Toby Strite, high power lasers marketing director for the Communications and Commercial Optical Products business segment at JDSU.
