Latest Patents

Cornwell holds a patent for a "Dispersion managed cable for unrepeatered systems." This invention combines optical fibers of different physical characteristics to produce a hybrid fiber. At the operating wavelength, this hybrid fiber exhibits a relatively large effective area along with desirable net dispersion and attenuation characteristics over the combined length of the system. The first fiber in this hybrid has a large effective area greater than 85 µm, an attenuation of less than 0.19 dB/km, and a dispersion greater than 10 ps/nm/km at 1550 nm. The second fiber has a smaller effective area, a dispersion of less than 10 ps/nm/km, and an attenuation of less than 0.23 dB/km at the same wavelength. Both fibers are designed to have a positive dispersion slope at 1550 nm and are spliced directly together.
