JUNE 7, 2007 -- India's Sterlite Optical Technologies Ltd. (search for Sterlite Optical Technologies), provider and integrated manufacturer of optical fiber, today announced that it has been granted a patent by the United States Patent & Trademark Office for the invention of its Sterlite DOF-LITE (LEA) singlemode optical fiber. Product Patent US 7,209,620,B2 for "Dispersion optimized fiber having higher spot area" was granted in April 2007, and is valid up to the year 2024.
Sterlite says its DOF-LITE LEA dispersion-optimized fiber with higher spot area is specially designed for long-haul, high-data-rate, and multi-wavelength transmission. Its profile design optimizes effective area, dispersion slope, and chromatic dispersion--the three critical fiber parameters that affect performance in DWDM system at the C and L bands. According to the company, the patented product is capable of reducing the fiber non-linear effect like four-wave mixing for better DWDM performance in the wavelength region of 1530- to 1565 nm (C-band) and 1565- to 1625 nm (L-band).
"Six patents were granted to Sterlite in the last year for product and process inventions," reports Pankaj Khanna, COO of Telecom Business at Sterlite Optical Technologies. "These patent grants have helped us establish our technology leadership in addition to the market leadership we already enjoy. Consumers can look forward to more innovations from Sterlite's Technology Development Team, as optical fiber gets closer to homes," he adds.
