Title:
長距離通信用シングルモード導波路
Document Type and Number:
Japanese Patent JP4331337
Kind Code:
B2
Abstract:
Disclosed is a single mode optical waveguide fiber having a segmented core. The relative indexes, the refractive index profiles and the radii of the segments are chosen to provide waveguide fiber properties advantageously used in severe environments, such as, undersea cables. The segmented core waveguide fiber has a negative total dispersion over the operating window, which serves to eliminate soliton formation. The key properties of dispersion zero, total dispersion cut off wavelength, attenuation, and effective area fall within desired ranges. The waveguide also features a low polarization mode dispersion.
