Optical Fiber Patent Granted For Sterlite
Sterlite Optical Technologies, an India-based global provider of optical fibers, telecommunication cables, and power transmission conductors has been granted a patent by the United States Patent & Trademark Office for invention of its Sterlite DOF-LITE (LEA) Single Mode Optical Fiber.
The 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 2024.
This dispersion-optimized fiber with higher spot area Sterlite DOF-LITE (LEA) 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 C&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 (C-band) and 1565 to 1625 nm (L-band).
Pankaj Khanna, COO (Telecom Business) of Sterlite Optical Technologies said,”6 patents were granted to Sterlite in the last year for product and process inventions. These patent grants have helped us establish ourselves in the technology and market sector.”
