Sterlite Optical Granted Optical Fiber Patent in USA

Sterlite Optical Technologies Ltd on June 07, 2007 has announced that it has been granted a patent by the United States Patent & Trademark Office for invention of its Sterlite DOF-LITE™ (LEA) Single Mode 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 Year 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 unique profile design optimizes 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).
