Sterlite Optical gets US Optical Fiber Patent

New Delhi, June 7: Country's leading global provider of optical fibers and telecommunication cables, Sterlite Optical Technologies Ltd today announced that it has been granted a patent by the US Patent and Trademark Office for invention of its Sterlite DOF-LITE (LEA) Single Mode Optical Fiber.

Product Patent US 7,209,620,B2 for 'Dispersion optimised fiber having higher spot area' was granted in April this year and is valid up to 2024.

''Six patents were granted to Sterlite in the last year for product and process inventions. 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,'' company's Chief Operating Officer (Telecom Business) Pankaj Khanna said in a statement.

This dispersion-optimised fiber with higher spot area (Sterlite DOF-LITE LEA) is specially designed for long haul, high data rate and multi wavelength transmission, he added.

Its unique profile design optimises effective area, dispersion slope and chromatic dispersion - the three critical fiber parameters that affect performance in DWDM system at C and L bands.

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 (Cband) and 1565 to 1625 nm (L-band).
